8d7e471fd3<!-- 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` -

## 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
## 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)
- [x] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update

Server JSON Examples
These examples show the PublishRequest format used by the /v0/publish API endpoint. Each example includes the server specification and optional x-publisher extensions for build metadata.
Basic Server with NPM Package
{
"server": {
"name": "io.modelcontextprotocol/brave-search",
"description": "MCP server for Brave Search API integration",
"status": "active",
"repository": {
"url": "https://github.com/modelcontextprotocol/servers",
"source": "github"
},
"version_detail": {
"version": "1.0.2"
},
"packages": [
{
"registry_name": "npm",
"name": "@modelcontextprotocol/server-brave-search",
"version": "1.0.2",
"environment_variables": [
{
"name": "BRAVE_API_KEY",
"description": "Brave Search API Key",
"is_required": true,
"is_secret": true
}
]
}
]
},
"x-publisher": {
"tool": "npm-publisher",
"version": "1.0.1",
"build_info": {
"timestamp": "2023-12-01T10:30:00Z"
}
}
}
Constant (fixed) arguments needed to start the MCP server
Suppose your MCP server application requires a mcp start CLI arguments to start in MCP server mode. Express these as positional arguments like this:
{
"server": {
"name": "Knapcode.SampleMcpServer",
"description": "Sample NuGet MCP server for a random number and random weather",
"version_detail": {
"version": "0.4.0-beta"
},
"packages": [
{
"registry_name": "nuget",
"name": "Knapcode.SampleMcpServer",
"version": "0.4.0-beta",
"package_arguments": [
{
"type": "positional",
"value": "mcp"
},
{
"type": "positional",
"value": "start"
}
]
}
]
},
"x-publisher": {
"tool": "nuget-publisher",
"version": "2.1.0",
"build_info": {
"timestamp": "2023-11-15T14:22:00Z",
"pipeline_id": "nuget-build-456"
}
}
}
This will essentially instruct the MCP client to execute dnx Knapcode.SampleMcpServer@0.4.0-beta -- mcp start instead of the default dnx Knapcode.SampleMcpServer@0.4.0-beta (when no package_arguments are provided).
