Two real defects, plus the CLI reference claims that go with them.
## 1. ECDSA P-384 login instructions cannot work
Every "ECDSA P-384" tab ran the *identical* command to the Ed25519 tab.
Since `--algorithm` defaults to ed25519
([login.go:100](https://github.com/modelcontextprotocol/registry/blob/main/cmd/publisher/commands/login.go#L100)),
a 96-hex key is rejected outright. Verified against a freshly generated
P-384 key:
```
$ mcp-publisher login dns --domain=example.com --private-key=$KEY
Signing in process using key algorithm ed25519
Error: failed to get token: failed to sign timestamp: invalid seed length: expected 32 bytes, got 48
$ mcp-publisher login dns --algorithm ecdsap384 --domain=example.com --private-key=$KEY
Signing in process using key algorithm ecdsap384
Expected proof record: # works
```
`--algorithm` is registered at
[login.go:129](https://github.com/modelcontextprotocol/registry/blob/main/cmd/publisher/commands/login.go#L129)
and described correctly by the CLI's own help, but `grep -rn algorithm
docs/` had **zero** hits for it. Anyone following the ECDSA path in the
docs hit that error with nothing to tell them why.
Fixed at all four in-process ECDSA sites (2 in `authentication.mdx`, 2
in `cli/commands.md`), with a note that cloud signing providers derive
the algorithm from the key itself so the flag does not apply to them.
## 2. `mcp-publisher validate --help` was broken
```
$ mcp-publisher validate --help
Unknown command: validate
...
Use 'mcp-publisher <command> --help' for more information about a command.
```
It printed the very instruction that had just failed. `main.go`
intercepted `--help` for all subcommands and called `printCommandHelp`,
whose switch had no `validate` case — making `ValidateCommand`'s own
help block
([validate.go:120-129](https://github.com/modelcontextprotocol/registry/blob/main/cmd/publisher/commands/validate.go#L120))
unreachable.
Rather than paste a third copy of the help text, `printCommandHelp` now
returns whether it handled the command, and the caller falls through to
normal dispatch when it did not. Commands own their own `--help`, and
any future command with this shape works automatically.
| Command | Before | After |
|---|---|---|
| `validate --help` | `Unknown command`, exit 0 | prints its help, exit
0 |
| `publish --help` | works | works |
| `init -h` | works | works |
| `bogus --help` | `Unknown command`, exit 0 | `Unknown command`, **exit
1** |
## 3. CLI reference corrections
- **`--registry` is not global.** It exists only on `login`; other
commands read the URL from the stored token. `publish --registry=URL`
silently treats the flag as the `server.json` path.
`cmd/publisher/README.md` had exactly this broken example.
- **`--token` was undocumented** despite `github-actions.mdx:123`
depending on it. Now documented, noting it is `login github` only.
- **`init` takes no flags** and does not prompt; it writes `TODO:`
placeholders. The reference said `init [options]` and "Prompts for
missing required fields".
- **Refreshed the `--help` transcript** in `quickstart.mdx`, which
listed only 4 of 6 commands. Now byte-for-byte identical to real output
(diffed).
- **Added `validate`** to the command list in `cmd/publisher/README.md`.
## Verification
`go build` and `go test ./cmd/...` pass. All four help paths exercised
with exit codes checked. The 23 `goconst` findings in `validate_test.go`
are pre-existing — identical count on pristine `main`, none in
`main.go`. Quickstart transcript diffed against real output.

The Key Files list in `cmd/publisher/README.md` includes a bullet for
`build.sh`, but there is no `build.sh` anywhere in the repo. The
publisher is built with `make publisher`, which runs `go build -o
bin/mcp-publisher ./cmd/publisher` (Makefile), so there is no separate
cross-platform build script.
The other three entries in the same list (`main.go`, `commands/`,
`auth/`) all exist. This removes the stale bullet so the list matches
the actual files in the directory.

## Motivation and Context
Fixes#637
Server lifecycle management (deprecation and yanking) is a standard
requirement for package registries. Use cases like rebranding, security
vulnerabilities, and end-of-life servers demand the ability to mark
servers as deprecated or deleted, with optional messaging to guide
consumers toward alternatives.
## Changes
### New API endpoints
- **`PATCH /v0/servers/{serverName}/versions/{version}/status`** —
Update the lifecycle status of a single server version
- **`PATCH /v0/servers/{serverName}/status`** — Update the lifecycle
status of all versions of a server in a single transaction
Both endpoints accept:
```json
{
"status": "active|deprecated|deleted",
"statusMessage": "Optional message (max 500 chars) explaining the change"
}
```
### New CLI command
- **`mcp-publisher status <serverName> [version]`** — Update server
lifecycle status from the command line
- `--status` (required): `active`, `deprecated`, or `deleted`
- `--message`: Optional status message
- `--all-versions`: Apply to all versions of the server (replaces the
`<version>` argument)
### API response changes
`RegistryExtensions` now includes two new fields:
- `statusChangedAt` — Timestamp of the last status change
- `statusMessage` — Optional free-form message (e.g., deprecation
reason, migration guidance)
### List endpoint changes
- New `include_deleted` query parameter on `GET /v0/servers` — defaults
to `false`, hiding deleted servers from listings
- When `updated_since` is provided, `include_deleted` is automatically
set to `true` for incremental sync
### Database
- Migration `013_add_status_fields.sql`: Adds `status_changed_at` (NOT
NULL, initialized from `published_at`) and `status_message` columns to
the `servers` table
### Design decisions (from review discussion)
- **Dedicated status endpoints** rather than overloading the existing
edit endpoint
- **Bidirectional status transitions** — all transitions between
`active`, `deprecated`, and `deleted` are allowed
- **`statusMessage` as free-form text** — no structured `nextName` or
`alternativeUrl` fields (per maintainer feedback, to avoid complexity
around chaining, trust transfer, etc.)
- **Publish permission** grants status change access (not limited to
admin/edit)
- **Status message auto-cleared** when transitioning back to `active`
Good, now I have the full picture. Here's the addendum:
### Consumer-facing API changes
The new status fields live inside
`_meta["io.modelcontextprotocol.registry/official"]` on every
`ServerResponse`. This is the existing `RegistryExtensions` object — two
new fields are added alongside the existing ones:
**Before:**
```json
{
"server": { "name": "com.example/my-server", "...": "..." },
"_meta": {
"io.modelcontextprotocol.registry/official": {
"status": "active",
"publishedAt": "2025-06-01T00:00:00Z",
"updatedAt": "2025-06-15T00:00:00Z",
"isLatest": true
}
}
}
```
**After:**
```json
{
"server": { "name": "com.example/my-server", "...": "..." },
"_meta": {
"io.modelcontextprotocol.registry/official": {
"status": "deprecated",
"statusChangedAt": "2026-02-01T12:00:00Z",
"statusMessage": "Deprecated in favor of com.example/my-server-v2",
"publishedAt": "2025-06-01T00:00:00Z",
"updatedAt": "2026-02-01T12:00:00Z",
"isLatest": true
}
}
}
```
| New field | Type | Present when |
|-----------|------|-------------|
| `statusChangedAt` | `string` (RFC3339) | Always — initialized to
`publishedAt` for existing records |
| `statusMessage` | `string` (max 500 chars) | Only when set —
`null`/omitted for active servers (auto-cleared on transition to active)
|
These fields appear on **every endpoint that returns a
`ServerResponse`**: `GET /v0/servers`, `GET /v0/servers/{name}`, `GET
/v0/servers/{name}/versions/{version}`, and the new PATCH status
endpoints.
### List endpoint filtering
`GET /v0/servers` gains an `include_deleted` query parameter:
| Scenario | Behavior |
|----------|----------|
| No `include_deleted` param | Deleted servers hidden (default `false`)
|
| `include_deleted=true` | Deleted servers included in results |
| `updated_since` provided | `include_deleted` forced to `true` for
incremental sync |
## How Has This Been Tested?
- Unit tests for status handler (`status_test.go`) covering status
transitions, permission checks, validation errors, and the all-versions
endpoint
- Unit tests for the CLI command (`status_test.go`)
- Integration with existing server/edit handler tests
- Database layer tests for the new status update and query methods
- Tested locally with `make dev-compose`

<!-- Provide a brief summary of your changes -->
## Motivation and Context
This allows the private key used for DNS or HTTP based authentication to
be stored securely in a cloud key management system. These services
often provide HSM storage which makes it very hard to leak the private
key.
The full context is described in my design document here:
https://github.com/modelcontextprotocol/registry/issues/482#issuecomment-3437117171
## How Has This Been Tested?
I have tested it against PROD using an Ed25519 key stored in Google KMS.
I have added unit tests. I have tested both ECDSA P-384 and Ed25519 with
Az KV and Google KMS against a locally running server.
## Breaking Changes
None intended.

## 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.

## 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
