## Summary
Updates the `_meta` field structure to be compliant with the MCP
specification by using proper `prefix/name` format for vendor
extensions.
### Changes
- **Registry metadata**: `io.modelcontextprotocol.registry` →
`io.modelcontextprotocol.registry/official`
- **Publisher metadata**: `publisher` →
`io.modelcontextprotocol.registry/publisher-provided`
- **Database migration**: Updates indexes to use new field paths
- **Updated all code**: Service layer, validators, tests, and seed data
### Format Before
```json
{
"_meta": {
"publisher": { "license": "MIT" },
"io.modelcontextprotocol.registry": { "id": "...", "is_latest": true }
}
}
```
### Format After
```json
{
"_meta": {
"io.modelcontextprotocol.registry/publisher-provided": { "license": "MIT" },
"io.modelcontextprotocol.registry/official": { "id": "...", "is_latest": true }
}
}
```
This resolves the naming collision with the planned top-level
`publisher` field and ensures compliance with MCP specification
requirements.
Fixes#356
Fixes Windows compatibility issue where filepath.Join uses backslashes
but embed.FS always expects forward slashes for embedded paths.
Fixes#337

## 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.
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.

<!-- Provide a brief summary of your changes -->
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
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 `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)
## 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

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

<!-- 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? -->
Motivated by the discussions in:
https://github.com/modelcontextprotocol/registry/discussions/284
## How Has This Been Tested?
<!-- Have you tested this in a real application? Which scenarios were
tested? -->
Locally and by running all of the tests
## Breaking Changes
<!-- Will users need to update their code or configurations? -->
Yes, it changes both the API and the format of the seed file

## 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.
## Motivation and Context
Currently there's a lot of unsafe manual JSON unmarshalling/marshalling,
and we have to manually keep the openapi schema in sync.
This PR migrates the API to
[Huma](https://github.com/danielgtaylor/huma), which appears like a
popular, well-maintained way to build APIs in Golang. I'm not a Golang
expert, but seemed highly recommended by Reddit + Claude and has a
decent star count. It provides automatic openapi spec generation and
docs hosting, JSON parsing, as well as the ability to add auth
middlewares etc.
## How Has This Been Tested?
Running locally, and poking at the endpoints
## Breaking Changes
Docs are served at `/docs` rather than `/v0/swagger/index.html` now

This PR simplifies the seed data import configuration based on
maintainer feedback by removing command line flags and using a clearer
environment variable name.
## Key Changes
### Configuration Simplification
- **Renamed**: `MCP_REGISTRY_SEED_FILE_PATH` → `MCP_REGISTRY_SEED_FROM`
- **Removed**: `--seed-file-path` command line flag to eliminate
configuration complexity
### Improved User Experience
Users now configure seed data import using a single, clear environment
variable:
```bash
# Before (multiple ways to configure)
MCP_REGISTRY_SEED_FILE_PATH=data/seed.json ./registry
./registry --seed-file-path=data/seed.json
# After (simplified single method)
MCP_REGISTRY_SEED_FROM=data/seed.json ./registry
```
### Registry Composability
The composability workflow is now simplified while maintaining all
functionality:
```bash
# Start first registry with seed data
MCP_REGISTRY_SEED_FROM=data/seed.json ./registry
# Start second registry importing from first via pagination
MCP_REGISTRY_SEED_FROM=http://localhost:8080 ./registry
```
## Technical Implementation
- Maintains full backward compatibility for import functionality
- All existing seed data sources continue to work (local files, HTTP
URLs, registry URLs)
- Automatic pagination through `/v0/servers` endpoint remains unchanged
- Configurable delays between requests preserved
## Benefits
- **Reduced complexity**: Single configuration method instead of
multiple
- **Clearer naming**: `SEED_FROM` better describes the source of seed
data
- **Easier maintenance**: Fewer configuration paths to test and document
- **Consistent patterns**: Aligns with other environment-variable-only
configuration
All existing functionality is preserved while providing a cleaner, more
maintainable configuration interface.

This is a first PR for #159 - adding some validation scripts. I want to
get to a place where we are confident that making schema changes is in
sync with the rest of our code. Step one is making sure the schemas are
in sync with our examples. Step two will be making sure the schemas are
in sync with our actual Registry implementation code.
This is just for the JSON right now; if we're feeling good about this
approach I'll do an analogous change for the OpenAPI schemas as well.
I'll also follow with adding usage of these scripts to our CI pipeline
so we have automated checks on them with every change.
## Summary
- Added CLI validation tools for JSON schemas and examples in
`docs/server-json/`
- Fixed some minor validation errors found in `examples.md`
- Ensures schema consistency and example validity in CI/CD pipelines
## Changes
### New Validation Tools
1. **`tools/validate-schemas`** - Validates that `schema.json` and
`registry-schema.json` are valid JSON Schema documents
2. **`tools/validate-examples`** - Validates all JSON examples in
`examples.md` against both schemas
### Key Features
- ✅ Validates JSON schema syntax and structure
- ✅ Validates all examples against both base and registry schemas
- ✅ Tracks validation counts to prevent silent failures
- ✅ Proper exit codes for CI integration
- ✅ Clear error messages for debugging
### Fixes to examples.md
- Added missing `repository.id` field in NuGet example
- Changed `repository.source` from "gitlab" to "github" in Docker
example
### Usage
```bash
# From repository root
./tools/validate-schemas.sh
./tools/validate-examples.sh
```
## Testing
I ran these scripts locally with minor (breaking) changes, which they
each correctly reported. As submitted, they are both passing.
