Title: GrantIQ MCP — US Federal Grants & Contracts for AI Agents

Subtitle: Search, match, and monitor every open SAM.gov and Grants.gov opportunity from any LLM, in one tool call.

GrantIQ MCP turns the messy world of US government funding into a clean, agent-ready API. Eight typed tools cover everything from broad keyword search and NAICS-coded contract discovery to deadline radar and historical award lookups. Responses are normalized across both data sources, returned as plain JSON, and cached for 24 hours so repeat queries don't burn rate limit on the upstream agencies.

Built for procurement copilots, grant-finder agents, and B2G sales tools, GrantIQ MCP ships with a free tier (50 calls/day) that any developer can drop into Claude or Cursor in 15 seconds. Upgrade to Pro for $19/mo for unlimited calls, or pay $0.02 per call for bursty workloads — billing flips a key from free to pro via a single webhook, with no app rewrites required.

claude mcp add grantiq-mcp --url https://mcp-grantiq.up.railway.app/mcp

Then add the API key Claude should use:

Tool reference

Every tool returns either:

{ "success": true,  "cached": false, "data": { ... } }

or, on failure:

{ "success": false, "error": "..." }

When the daily limit is hit, the HTTP layer returns 429 with body:

{ "error": "Limit reached. Upgrade at mcpize.com/grantiq-mcp" }

curl examples

The MCP endpoint speaks the JSON-RPC streamable-HTTP protocol and is best used through an MCP client. For convenience, every tool also has a REST mirror at /tools/<tool>.
