xrMCP Registry

The official registry of xrMCP tool manifests. Each tool is a single .xrmcp.json file that describes an API — its inputs, outputs, authentication, and how to map the response.

Install a tool

Using the xrMCP CLI:

xrmcp tool install jira/get_jira_ticket

Or directly with curl:

curl -X POST http://localhost:7373/tools/register \
  -H 'content-type: application/json' \
  -d @- <<< $(curl -fsSL https://raw.githubusercontent.com/xrmcp/registry/main/xrmcp-registry/tools/jira/get_jira_ticket.xrmcp.json)

Structure

xrmcp-registry/tools/
├── metadata.json          # searchable index of all tools
├── jira/
├── gitlab/
└── jsonph/

metadata.json is used by the CLI for xrmcp tool search <keyword> — it is fetched once and searched locally without downloading every manifest.
