Fixie MCP Registry Files

This directory holds the public MCP Registry metadata that can be pushed to:

  • https://github.com/onikora/mcp-registry

Files:

  • server.json - MCP Registry metadata for the deployed Fixie MCP server
  • USAGE.md - tool, resource, prompt, and usage examples
  • CHANGELOG.md - public metadata change history

Current remote endpoint:

  • https://www.onikora.com/mcp

Why this directory exists:

  • keep public MCP registration metadata separate from the private or broader webapp codebase
  • update the deployed MCP server and the published registry metadata in sync
  • give you a minimal payload to push to the public mcp-registry repository

Sync rule:

  • if the public MCP server URL, version, tool surface, resource surface, prompt surface, or title/description changes, update these files before publishing the new registry metadata

Current scope:

  • parse raw FIX messages for troubleshooting and inspection
  • provide Fixie initiator recipes for market data, order entry, and quote request workflows
  • generate generic Java initiator source and runtime configuration templates
  • expose human-readable docs and examples through MCP resources
