The README prerequisites were both stale, and the docs restated the Go
version in three places.
## Prerequisites: name the source, do not restate the version
| README said | Reality |
|---|---|
| `Go 1.24.x` | `go 1.26` in
[go.mod](https://github.com/modelcontextprotocol/registry/blob/main/go.mod)
|
| `golangci-lint v2.4.0` | `v2.11.4` pinned in
[ci.yml:30](https://github.com/modelcontextprotocol/registry/blob/main/.github/workflows/ci.yml#L30)
|
Rather than swap in fresher numbers — which only resets the clock on the
same drift — this **removes the numbers** and names the authoritative
file:
```
- **Go** - version per the `go` directive in go.mod; the Go toolchain fetches it for you
- **golangci-lint** - version per the `golangci-lint-action` pin in ci.yml, so local lint matches CI
```
The Go version was stated in **three** places, which is exactly why all
three drifted together. All three now point at a single source, so the
prerequisites list cannot go stale.
Two notes on why the numbers earn so little in prose:
- **Go corrects itself.** `go.mod` has no `toolchain` directive, so
under the default `GOTOOLCHAIN=auto` the toolchain downloads the
required version automatically. A contributor on an older Go gets an
upgrade, not a failure — it only hard-errors under `GOTOOLCHAIN=local`.
(An earlier version of this description said such a contributor "cannot
build"; that was too strong.)
- **golangci-lint does not.** Version skew here genuinely changes what
you see: running CI's config under a newer golangci-lint (2.12.2)
surfaces 23 `goconst` findings in
`cmd/publisher/commands/validate_test.go` that CI's pinned 2.11.4 does
not report. That is why the README now points at the pin rather than a
number someone has to keep in sync.
## `make check` does more than documented
Documented in three files as "lint, unit tests and integration tests".
Actually [`check: dev-down lint validate
test-all`](https://github.com/modelcontextprotocol/registry/blob/main/Makefile#L85)
— it also runs schema validation and **stops your running `dev-compose`
environment**. Worth knowing before running it mid-session. The
Makefile's own `##` help string already said this correctly; only the
prose was stale.
## Other verified corrections
- **README project structure** omitted `cmd/registry/` — the server
entry point and ko/goreleaser build target — and `internal/importer/`.
- **`tests/integration/README.md`** said the suite launches **MongoDB**.
It launches PostgreSQL (`postgres-integration-test`), as the same file
admits nine lines later. It also cited `/v0/servers/{server_id}`, a path
removed a while ago; the test actually calls `GET /v0/servers` and `GET
/v0/servers/{serverName}/versions/latest`
([main.go:210,255](https://github.com/modelcontextprotocol/registry/blob/main/tests/integration/main.go#L210)).
- **`scripts/mirror_data/README.md`** pointed at
`internal/database/migrations/008_separate_official_metadata.sql`, which
does not exist — that migration is `009_`, while `008_` is
`clean_invalid_data.sql`. (Migration 008's own header still calls itself
"007a", which is how the numbering slipped.) Also swapped two "edit line
NN" pointers for identifier names, since both had already drifted
(`maxMigration` is at :30 not :24; the connection string at :23 not
:17), and corrected the fetch URL from `/v0.1/servers` to the
`/v0/servers` the script actually requests.
- **`.env.example`** was missing
`MCP_REGISTRY_ENABLE_REGISTRY_VALIDATION`, even though the config reads
it
([config.go:18](https://github.com/modelcontextprotocol/registry/blob/main/internal/config/config.go#L18))
and README:50 tells contributors to set it while pointing at
`.env.example` as *the* reference.
- **`docker-compose.yml`** set `MCP_REGISTRY_ENVIRONMENT`, which nothing
reads — no `ENVIRONMENT` env tag in `internal/config`, and no other
occurrence in the repo. Removed. (The Pulumi-side
`mcp-registry:environment` key is a separate, real thing and is
untouched.)
- **Deleted `CHANGES.md`** — 0 bytes, untouched since the squashed
history base, zero references anywhere.
## Verification
`docker compose config` validates. `grep` for `Go 1.x` / `golangci-lint
vX` across all `.md`/`.mdx` now returns nothing outside `complete.md`
(which #1522 deletes). Both `../../README.md#pre-requisites` links
resolve and the anchor matches the real `#### Pre-requisites` heading.

Co-authored-by: Claude Opus 5 <noreply@anthropic.com>
Wielded Claude Code to do this; across many iterations and have reviewed
all the code + largely rewritten the PR commentary here.
This PR implements the server ID consistency changes from
[#396](https://github.com/modelcontextprotocol/registry/issues/396). Our
goal is to:
- Rename `id` to `versionId` to make it clear that it is the ID for a
specific version, not a server
- Introduce `serverId` as a net new concept. This will be 1:1 with
`name`. While not strictly necessary (we could just use name as a PK),
the convention of having a UUID as an ID on our objects is just a
helpful subjective architecture decision. Plus also leaves open the door
to reconsidering the "should we allow renames" question.
## Key Changes
### 🗄️ Database Schema Changes
- **Renamed**: `id` column → `version_id` (unique identifier for each
server version)
### 📋 Metadata Structure Updates
- **JSON Schema**: Updated
`_meta.io.modelcontextprotocol.registry/official` to include:
- `serverId`: Consistent ID across all versions of a server
- `versionId`: Unique ID for this specific version (renamed from `id`)
### 🔧 API Endpoint Updates
- **New endpoint structure**: Changed from version-ID-based to
server-ID-based URLs:
- `GET /v0/servers/{server_id}` - Get latest version of server
- `GET /v0/servers/{server_id}?version=X.X.X` - Get specific version
- `GET /v0/servers/{server_id}/versions` - List all versions of a server
- `PUT /v0/servers/{server_id}?version=X.X.X` - Edit specific version
- **Consistent URL patterns**: All server endpoints now use `server_id`
as the primary identifier
### Database Migration Strategy
The migration (`005_add_server_id_rename_version_id.sql`):
1. Adds new `version_id` column
2. Generates deterministic UUIDs for servers with the same name
3. Updates JSON metadata to add `serverId` and rename `id` to
`versionId`
4. Copies existing `id` values to `version_id` column
5. Drops old `id` column and makes `version_id` the new primary key
## Testing
Besides of course automated tests passing, I:
1. Set up my local db with the pre-005-migration state, imported all the
production data
2. Ran the migration
3. Spot checked some diffs of the data that resulted --
```json

## Motivation and Context
Docs currently don't have very clear organisation, and don't explain
core flows.
This fixes#89 (although we still might want to push these to
`https://modelcontextprotocol.io/docs/`), based on the plan there.
One minor change from that plan is that I merged tutorials and guides,
because they ended up basically being duplicates which I thought would
be annoying for us to keep in sync. Additionally in the Diátaxis
framework, tutorials and guides are separated by whether they are
focused on acquisition of skills (e.g. in a learning environment) or
application of skills (e.g. in a work environment). I expect the
registry to be something that will be used occasionally in a work
environment, rather than a fundamental 'learnable' skill so I think it's
reasonable not to have tutorials and fold these into guides.
## How Has This Been Tested?
- Read through all these updated docs
- Unit and integration tests (that previously used examples.md and use
the schema) working
- Ran `npx markdown-link-check .` to check all the links work
## Breaking Changes
Links to old docs will break, but I don't think there are any. All
internal links have been checked and updated.
## Types of changes
<!-- What types of changes does your code introduce? Put an `x` in all
the boxes that apply: -->
- [ ] Bug fix (non-breaking change which fixes an issue)
- [ ] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
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.

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.
