Connect a client

Rubricary runs an MCP server at https://app.rubricary.com/api/mcp. Once an agent is connected, it can search the catalog, read a prompt and its evals, and score a draft, all from inside the editor. Nothing to install and no key needed for the public catalog.

Claude Code

One command registers it:

1claude mcp add --transport http rubricary https://app.rubricary.com/api/mcp

Add --scope project to write it to the repository's .mcp.json so the whole team gets it. /mcp inside a session shows whether it connected.

Cursor

Add it to .cursor/mcp.json in the project, or ~/.cursor/mcp.json for every project:

1{
2  "mcpServers": {
3    "rubricary": {
4      "url": "https://app.rubricary.com/api/mcp"
5    }
6  }
7}

VS Code

Add it to .vscode/mcp.json:

1{
2  "servers": {
3    "rubricary": {
4      "type": "http",
5      "url": "https://app.rubricary.com/api/mcp"
6    }
7  }
8}

Any other client

Any client that speaks Streamable HTTP can use it. Most take a config shaped like this:

1{
2  "mcpServers": {
3    "rubricary": {
4      "type": "http",
5      "url": "https://app.rubricary.com/api/mcp"
6    }
7  }
8}

To check the server is reachable before wiring a client, curl https://app.rubricary.com/api/mcp returns its name, version and tool list. The tools themselves are in the tool reference.
