Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http us-federal-grants-finder-mcp https://us-federal-grants-mcp.donniertf.workers.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add us-federal-grants-finder-mcp --url https://us-federal-grants-mcp.donniertf.workers.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable us-federal-grants-finder-mcp in your MCP settings.
