Update all documentation to reference the stable `/v0.1/` API version
instead of the development `/v0/` version.
Didn't update internal references (e.g. in admin-only docs) as that
probably make sense to keep pointed at v0 as the "dev" option.

Change Format constant from `file_path` to `filepath` to match the
OpenAPI schema definition.
This is not used by any servers yet, nor is it enforced by the database,
so it's safe to change.
## Summary
- Fixes migration 008 failing with "column contains null values" error
- Adds COALESCE protection to handle 126 servers without status fields
- Includes test utilities to reproduce and verify fixes with production
data
## Problem
Migration 008 was failing in production because:
- 126 out of 781 servers have no `status` field in their JSON
- When extracting `rec.value->>'status'`, these became NULL values
- The `ALTER TABLE servers ALTER COLUMN status SET NOT NULL` constraint
then failed
## Solution
1. **Prevent NULLs during migration**: Use COALESCE to provide 'active'
default when status is NULL/empty
2. **Enhanced debugging**: Added RAISE NOTICE statements to log
problematic values
3. **Safety check**: Double-check that throws exception if any NULLs
remain
4. **Test utilities**: Created mirror_data tools to test migrations with
real production data
## Testing
Created and used `scripts/mirror_data/` tools to:
- Fetch all 781 servers from production API
- Load them into a test database
- Verify the migration fix works correctly
### Results:
- **Before fix**: 126 NULL status values created during migration
- **After fix**: 0 NULL status values, all servers have valid status
- Migration completes successfully with NOT NULL constraint
## Test plan
- [x] Tested locally with production data using mirror_data tools
- [x] Verified 0 NULL values after migration (vs 126 before)
- [x] Confirmed NOT NULL constraint adds successfully
- [ ] Deploy to staging and verify migration succeeds
- [ ] Monitor production deployment

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

## Summary
Simplified the schema structure by:
- Replacing `version_detail.version` with direct `version` field
- Removing unused `release_date` field from seed data
- Updating all API types, models, and tests to match new structure
- Maintaining backwards compatibility in API responses
This change makes the schema more intuitive and reduces nesting depth.
## 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 -->
Hi Folks, thanks for the great work on MCP Registry!
While running it locally, I noticed a bug with the `make dev-local`
command.
```
$ make dev-local
go run ./cmd/registry/main.go
# command-line-arguments
cmd/registry/main.go:29:36: undefined: Version
cmd/registry/main.go:30:34: undefined: GitCommit
```
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
Command for running MCP Registry locally is broken.
## How Has This Been Tested?
<!-- Have you tested this in a real application? Which scenarios were

I originally introduced `package_canonical` into the API schema because,
at the time, we were thinking to "pin" the version of the MCP server to
_one_ of the referenced source code packages.
We are no longer doing this (we are maintaining a separate notion of
`version` unique to the MCP server), so I don't believe
`package_canonical` is needed anymore. Does anyone see otherwise?
This change removes all mentions in READMEs and usages in code.
Work in progress .
This commit adds the core registry service implementation with methods to:
- Retrieve all registry entries
- List entries with cursor-based pagination
- Fetch specific server details by ID
