## Motivation and Context
The database logic was getting a bit unwieldy and fragile - especially
because business logic that should really have lived at the registry
service level was being pushed into the persistence level.
This PR tightens the interface, simplifies the code there, as well as
rips out a bunch of mocks etc. we don't need.
## How Has This Been Tested?
Locally everything works
## Breaking Changes
The list endpoint was surprisingly always filtering for isLatest only,
which seems like a bug? I have removed this filter.
## Summary
- Updates all server.json examples to use `io.github` namespace instead
of `com.github`
- Fixes validator test case to use proper domain format
- Aligns with standard reverse domain name convention for GitHub-hosted
projects
This change improves consistency across documentation examples and
follows established naming conventions.
## Summary
Fixed grammar issues in the README description for better readability.
## Motivation and Context
The registry description had a sentence fragment and missing article
that made it harder to read smoothly.
## How Has This Been Tested?
N/A - text-only changes to documentation.
## Breaking Changes
None.

Updates the registry type for all Docker Hub packages in the seed data
from `docker-hub` to `oci` to align with the standardized OCI registry
format. This change affects the `registry_type` field and simplifies the
`identifier` field by removing the full Docker Hub URL prefix.
Changes:
- Updated `registry_type` from `docker-hub` to `oci` for all Docker
packages
- Simplified `identifier` field to use just the repository name/path
instead of full URLs
- Maintained `registry_base_url` as `https://docker.io` for all entries
This refactoring improves consistency and aligns with OCI standards
while maintaining backward compatibility through the registry base URL.

## Summary
Move the publisher CLI from `tools/publisher/` to `cmd/publisher/` as
it's a proper application rather than a development utility.
This addresses feedback from @rdimitrov in PR #324 that the publisher
CLI should be under `cmd/` since it's not really a tool in the same
sense as other helpers in the `tools/` folder.
## Changes
- Moved `tools/publisher/` directory to `cmd/publisher/`
- Updated Makefile build and clean targets
- Updated README.md documentation links
- Updated VS Code launch configuration
- Updated integration test script
- Updated FAQ documentation
- Fixed Go import paths in publisher code

## Summary
- Improved command structure and organization for the MCP Publisher CLI
- Enhanced readability and maintainability of publisher commands
- Cleaned up publish and edit handler logic
This builds on the previous cleanup work to further streamline the
publisher interface.
This also works as part of
https://github.com/modelcontextprotocol/registry/issues/89
Originally by @dmartinol. This branch is an attempt by @domdomegg to fix
the merge conflicts...

## Motivation and Context
Closes#145
Add comprehensive validation for named arguments in MCP server packages
to ensure argument names, values, and defaults follow proper format
conventions. This prevents common issues where argument names contain
embedded values or descriptions, and where values/defaults incorrectly
start with the argument name itself.
Key changes:
- Add ArgumentValidator with validation rules for named argument format
- Enhance PackageValidator to validate runtime and package arguments
- Update import process to log warnings for invalid servers instead of
failing
- Fix 396 servers in seed.json with malformed named arguments
- Extended `validate-examples` tool to apply the object validator (it
was completely missed before)
- Add comprehensive test coverage for all validation scenarios
Examples of fixes applied:
- "--directory <path>" → "--directory" with value "<path>"
- "--with-editable $REPO" → "--with-editable" with value "$REPO"
- "recipient@example.com" → "--recipient" (proper argument naming)
All servers now pass validation during both API publishing and data
import.
🤖 Generated with [Claude Code](https://claude.ai/code)
## How Has This Been Tested?
With ad-hoc unit tests.
Manual integration tests of built artifact and the seed data.
## Breaking Changes
New registrations need to follow the argument name conventions,
otherwise the import would fail for the inconsistent servers.

## Summary
- Added comprehensive admin operations documentation
- Included scripts for common server management tasks
Together with #315, #316, this fixes#182
Thanks Camila for being a great Go consultant and advising on how to
tidy this up!
(I'm still a lil grumpy about some parts, but it's in much better shape
😄)
- Consolidated publisher extension validation into a single function.
- Updated the `Publish` and `EditServer` methods to directly use
`XPublisher` from the request.
- Removed outdated tests for publisher extension extraction and
validation.
- Introduced new validation functions for server details and remote URL
matching.
- Enhanced error handling for server name format and remote URL
validation.
- Updated existing tests to reflect changes in validation logic and
structure.
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
Things were starting to become a bit spaghetti-y after lots of small PRs
and contributions from many people. Camila and I went through and
figured out how we could make this a lot cleaner.
## How Has This Been Tested?
<!-- Have you tested this in a real application? Which scenarios were
tested? -->
Tested locally, plus all the integration and unit tests still pass.

The following PR eliminates duplicate struct definitions by migrating
the publisher tool to use canonical types from pkg/model, creating a
single source of truth across the codebase. The publisher tool
previously had its own copies of structs that were duplicated, ie.
ServerJSON, Package, Repository, VersionDetail, EnvironmentVariable,
RuntimeArgument and a few others which was not optimal
**Changes in the PR:**
- Refactored the structs to single canonical types located at pkg/model
- Refactor the implementation to use/build canonical structures directly
- Remove all duplicate definitions (5 structs eliminated)
- Publisher now uses model.ServerJSON, model.Package, model.Repository,
etc.
- Renamed some of the structs to better reflect their use case, i.e.
ServerJSON instead of ServerDetail
- Fixes an issue where the Remote property was missing from the previous
publisher copy of the Server
**Benefits:**
- Single source of truth - Schema changes in one place
- Type safety - Compiler catches mismatches
- Enhanced validation - Field constraints and bson tags
- Zero breaking changes - Same CLI interface and JSON output
- Future-proof - New canonical fields automatically available
Supersedes: #217 and #240

## Summary
Implements a denylist mechanism to prevent blocked namespaces from
publishing packages:
- Added `BlockedNamespaces` field to `JWTManager` struct for maintaining
the denylist
- Added validation logic in `GenerateTokenResponse` that checks user
permissions against blocked namespaces
- Admins with global permissions (`*`) bypass the blocking logic
- Added comprehensive test coverage for all blocking scenarios
Fixes#98
## Summary
Implements `PUT /v0/servers/{id}` admin edit endpoint to address part of
issue #182, providing an API-based solution for server moderation
without requiring direct database access.
- **New endpoint**: `PUT /v0/servers/{id}` for editing existing servers
- **Security**: Uses existing JWT auth with `PermissionActionEdit`
permissions
- **Anti-undelete protection**: Added `ServerStatusDeleted` status that
cannot be reverted
- **Full implementation**: Database, service, API, and comprehensive
test coverage
## Key Use Cases
- Mark malicious servers as `deleted` for takedown
- Update server metadata for moderation actions
Related to: https://github.com/modelcontextprotocol/registry/issues/182
(but that is not _done_ yet because we need admins to be able to login
(probably with #283), and need to add docs on how to do the takedown,
and probably guidelines on what we will/won't takedown)
## Summary
This PR implements OIDC authentication support for admin users,
specifically configured for Google Cloud Identity. The implementation
includes:
- Configurable OIDC authentication endpoints and validation
- Google Cloud Identity integration for admin access
- JWT token validation and user session management
- Deployment configuration updates for OIDC provider settings

## Description
This PR addresses #300 by adding explicit versioning to the MCP Registry
API OpenAPI specification.
## Changes
- Added `version: "2025-07-09"` field to the `info` section of the
OpenAPI specification
- Maintains consistency with existing date-based versioning used across
all schema files
## Rationale
As outlined in #300, the OpenAPI spec was missing an explicit version
field, which could lead to:
- Compatibility issues as the API evolves
- Lack of clarity for API consumers
- Missing functionality in OpenAPI tooling that expects a version field
This follows the MCP specification's date-based versioning approach.
Closes#300
## Motivation and Context
- Add MCPB as a new registry_name option
- Add file_hashes field to package model for integrity verification
- Implement URL validation restricting MCPB packages to GitHub/GitLab
hosts
- Require SHA-256 hash for all MCPB packages
- Add example MCPB package in documentation
- Update schemas and OpenAPI specification
See issue #260

<!-- Provide a brief summary of your changes -->
The changes are intended to create validators for all the free-form
fields. Please find the details of the validation of different field
below.
- Repository.Source: only github and gitlab is accepted.
- Repository.Url - It should be a valid github or gitlab URL. Created
regex for both.
- Server.Name - Max 200 char can be there. Reverse domain name
verification is part of another PR (not owned by me).
- Package.Name - Max 200 char and no spaces.
- Server.Description - Max 100 char.
- Remote.Url - It should be valid URL.
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
The motivation was to make the code clean and add base code for more
validator for different objects like Repository etc.
https://github.com/modelcontextprotocol/registry/issues/97
## How Has This Been Tested?
It's tested via UTs. Added UT's for all the validations.

## Summary
- Restructure main README to focus on registry purpose and quick start
guide
- Streamline docs/README.md with better organization and linking
- Update FAQ with current publishing methods, security approach, and
community practices
- Simplify roadmap to focus on go-live blockers rather than exhaustive
backlog
- Add ecosystem diagram to visualize registry architecture
## Summary
- Disable the `ireturn` linter rule in golangci-lint configuration
- Remove all related `nolint:ireturn` comments from the codebase
The `ireturn` rule was flagging factory functions that intentionally
return interfaces for dependency injection, which is a common and valid
Go pattern. Since this pattern is used extensively throughout the
codebase for good architectural reasons, it makes sense to disable this
rule entirely.
It also seems buggy, and seems to conflict with other lint rules -
causing unnecessary toil.See:
https://stackoverflow.com/questions/72385337/golang-linter-always-complains
## Summary
- Updates server names in documentation examples from arbitrary strings
to reverse DNS format (com.github.owner/repo)
- Standardizes package names and URLs for consistency across all
examples
- Improves naming convention to follow established patterns
This change makes the examples more consistent and follows common
reverse DNS naming conventions used in software development.
This implements the versioning approach agreed upon in issue #158:
## Key Changes
### Documentation
- Added comprehensive versioning guide (docs/versioning.md)
- Updated FAQ with versioning guidance and best practices
- Enhanced schema description with SHOULD recommendations
### Schema Updates
- Added 255-character limit for version strings in schema.json
- Enhanced version field description with semantic versioning guidance
### Implementation
- New isSemanticVersion() function for proper semver detection
- Enhanced compareSemanticVersions() with prerelease support
- Implemented compareVersions() strategy:
* Both semver: use semantic comparison
* Neither semver: use timestamp comparison
* Mixed: semver versions always take precedence
- Updated publish logic to determine "latest" using new strategy
- Added version length validation (255 char max)
### Versioning Strategy
1. Version MUST be string up to 255 characters
2. SHOULD use semantic versioning for predictable ordering
3. SHOULD align with package versions to reduce confusion
4. MAY use prerelease labels for registry-specific versions
5. Registry attempts semver parsing, falls back to timestamp ordering
6. Clients SHOULD follow same comparison logic
Resolves#158

This PR adds a new example to the OpenAPI specification that
demonstrates the publisher extensions feature recently added in #298.
## Changes
- Added \`example_org_server\` example to the OpenAPI spec
- Demonstrates \`x-publisher\` fields for contact email and build
metadata
- Shows organization-specific extensions (\`x-com.example\`) including:
- Marketplace icon URL
- Category classification
- Documentation URL
- Verified publisher status
This example helps developers understand how to use the new vendor
extensions functionality when publishing servers to the registry.

<!-- Provide a brief summary of your changes -->
This PR serves as a placeholder and brings together all of the changes
related to supporting vendor extensions passed through the API. The idea
is to have a single place to track and review the work as it comes
together (even if it’s still a bit of a work in progress).
**The changes in this PR cover:**
* Updates on the data model
* Updates on both databases (in-memory and postgresql), added a new
table to PSQL for tracking the extensions leaving the server table only
for the clean server.json properties
* Updates the seed.json file (thus the big line change)
* Adds a seed-migrate tool to help migrating an existing seed file to
the new format
* Updates the seed import mechanism to support this
* Updates the existing tests - unit, integration and validation tests
* Adds the publish handler to the OpenAPI spec (it was missing)
* Fixes linting errors
* Updates on the API side on (publish, list, get) to support the new
format of `ServerResponse` -
```
{
"server": {},
"x-io.modelcontextprotocol.registry": {}, /*not available for publish since this gets populated by the registry*/
"x-publisher": {}
}
```
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->

- [x] I have added or updated documentation as needed
## Additional context
I have not implemented connection pooling support for simplicity, and
because cloudnative-pg already provides built-in connection pooling with
pgBouncer so if we want it later we can switch to this endpoint easily.
Add HTTP-based authentication to prove domain ownership, similar to
https://github.com/modelcontextprotocol/registry/pull/238's DNS
authentication but using HTTPS well-known URIs instead of DNS TXT
records.
Fixes#280
## Motivation and Context
Some organizations don't have easy access to DNS records, but can easily
deploy web assets. They would therefore prefer to be able to complete a
HTTP challenge rather than a DNS one to authenticate to the registry.
This would in some way mirror ACME challenges: where you can do a DNS-01
or a HTTP-01 challenge.
## How Has This Been Tested?
- Tested locally by stubbing out the HTTP getter
- Added unit tests

## Additional context
I concern I had when building this that it might expose us to SSRF
attacks.
I think on reflection this is not a significant problem:
- We only GET a fixed file `.well-known/mcp-registry-auth` (redirects
disallowed) after sanitizing the domain, and then also don't expose the
response to the user. This means the user shouldn't be able to hit
anything very interesting.
- The information they might get is what domains/servers exist in the
network. Our infrastructure is already all open-source, so attackers
aren't getting any additional real info by prodding at the environment
this way.
Fixes#270Closes#233
Adds support for DNS-based authentication for proving ownership of a
particular domain. E.g. if you can add a TXT record to `anthropic.com`,
you can publish anything at `com.anthropic/*` or `com.anthropic.*`.
Notes:
- Uses Ed25519 signatures with 15-second timestamp windows to prevent
replay attacks
- Supports multiple public keys in DNS TXT records for key rotation
scenarios
- Publisher CLI supports DNS auth via --dns-domain and --dns-private-key
flags
- Includes key generation commands in publisher README for easy setup
## Motivation and Context
This implements DNS-based public/private key authentication to allow
people to actually publish at their own domains. Currently,
authentication requires GitHub accounts which limits publishing to the
io.github.* namespace.
DNS-based auth enables:
- Publishing under your actual domain (e.g., com.anthropic/* for
anthropic.com)
- Independence from GitHub or other external auth providers
- Organizations managing their own keys and access to publishing
## How Has This Been Tested?
- Unit tests cover signature verification, DNS TXT parsing, timestamp
validation, and error cases
- Tested locally by editing my own DNS records
- All existing auth methods covered by passing tests

## Additional context
Will be adding HTTP challenge auth in a similar way as a separate PR,
e.g. for verifying you own `github.com` by hosting a
`github.com/.well-known/mcp-server-challenge` or similar. Just
mentioning this as we discussed HTTP challenges as closely related to
DNS challenges elsewhere, and want to reassure reviewer that this hasn't
been forgotten with this approach. :) Update: tracking the HTTP auth in
https://github.com/modelcontextprotocol/registry/issues/280
Make repository.id optional by:
- Removing 'id' from required fields in JSON schema
- Adding omitempty tags to Go model structs
- Updating examples to show simpler format without id
This fixes publishing failures where the publisher tool doesn't
generate repository.id but the schema requires it.

Create a separate step in the Docker image to install the dependencies.
This makes local dev a bunch faster, because Docker doesn't redownload
all the dependencies each time you make a small file changes.
Updates golangci-lint version references from v2.3.1 to v2.4.0.
Changes:
- README.md: Updated prerequisites documentation and installation
command
Note: The CI workflow file (.github/workflows/ci.yml) also needs
updating but requires additional permissions.
Fixes#287

## Motivation and Context
- It is important to have basic observability in place so that
availability issues can be figured out easily
## How Has This Been Tested?
- Registration of metrics is tested
- Prometheus endpoint `/metrics` is included in test cases to test the
metrics exposed
- Test locally to understand any regression.
## Breaking Changes
- No

## Additional context
- Telemetry implementation is currently done by keeping metrics in mind
as of now, other types of telemetry can be added on top of it later.
- Instrumentation takes care of these problems already:
- Cardinality control by limiting latency buckets and not including
labels that grows with throughput.
- Latency buckets are added as per SLA guidelines
- Each metric prefixed with `mcp` to easily identify.
- Pulling mechanism is used since the idea is to scrape metrics via an
agent like vmagent, prometheus agent or otel-collector.
- Metrics follow standard approach of defining counters, histogram and
gauges as per opentelemetry guidelines.
Adds support for auth'ing to the registry via [GitHub Actions
OIDC](https://docs.github.com/en/actions/concepts/security/openid-connect).
Fixes#271
## Motivation and Context
People will probably want to publish to the registry from CI
environments. DNS auth can work here fine
(https://github.com/modelcontextprotocol/registry/issues/270). But for
people who haven't set up DNS, the standard GitHub device flow won't
really work here. We could make this nice by supporting GitHub Actions
OIDC.
## How Has This Been Tested?
Tested locally with a real GitHub OIDC token from a personal repo.

Merging based on Tadas's approval review, and only making minor docs changes on top of that.
## Motivation and Context
In staging (and prod, for now) we pull the `:latest` mcp-registry image.
But K8s won't actually change anything unless we recreate the pods.
This change ensures the workflow goes from docker -> staging -> prod,
and changes the annotation so that the pods are recreated each deploy.
This ensures they actually pull the latest version.
## How Has This Been Tested?
Deployed locally to minikube

Fixes#264. Adds endpoints:
```
/v0/auth/github # exchange a github token for a registry token that gives you access to namespaces io.github.username and io.github.org for your orgs
/v0/auth/none # get a registry token for namespace io.modelcontextprotocol.anonymous (only for testing/local dev purposes)
```
Updates `/v0/publish` to accept one of these registry tokens.
## Motivation and Context
See #264
## How Has This Been Tested?
- Running locally and getting a token from `/v0/auth/none` and then
publishing to `/v0/publish`
- Updating the integration tests that get a token and then publish, and
them passing
## Breaking Changes
This is a breaking change to the auth API. This is fine for registry
given it's not deployed yet.

The Always pull policy is needed for the latest tag to force Kubernetes
to pull the newest image on every pod creation, even if an image with
that tag already exists locally. Without this, pods might use outdated
cached versions since the latest tag is mutable and can point to
different images over time.
