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.

Install

claude mcp add grantiq-mcp --url https://mcp.grantiq.us/mcp/

Then add the API key Claude should use:

claude mcp env grantiq-mcp X-API-Key=your-api-key

There is no shared public key. Mint one with the admin endpoint below (free tier is 50 calls/day) and store it in the client config or an environment variable.

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/ .

# Search grants

Operator endpoints

Mint a fresh key (free or pro):

curl -s https://mcp.grantiq.us/admin/keys \

-H 'X-Admin-Token: $GRANTIQ_ADMIN_TOKEN' \ -H 'Content-Type: application/json' \ -d '{"tier":"free","daily_limit":50}'

Promote a free key to pro (called from the Stripe checkout success webhook):

curl -s https://mcp.grantiq.us/billing/upgrade \

-H 'X-Admin-Token: $GRANTIQ_ADMIN_TOKEN' \ -H 'Content-Type: application/json' \ -d '{"key":"grantiq_xxxxx"}'

---

Local dev

python -m venv .venv && source .venv/bin/activate

pip install -r requirements.txt cp .env.example .env

Replace the placeholders, then export them. The process refuses to start

until GRANTIQ_ADMIN_TOKEN is a real value (not the example placeholder).

set -a && source .env && set +a python server.py # http://localhost:8000 pytest -v # 31 tests, hermetic with respx mocks

Deploy to Railway

The repo includes nixpacks.toml. After railway init, just railway up. The start command is python server.py (not uvicorn ...) because Railway exec's [start].cmd without a shell — server.py reads $PORT via os.getenv and starts uvicorn programmatically.

Set these on the Railway service:

• SAM_API_KEY — your SAM.gov key (contract tools fail closed without it)
• GRANTIQ_ADMIN_TOKEN — long random string, required at startup
• GRANTIQ_DB_PATH — /data/grantiq.db if you mount a Volume (recommended so cache + keys survive deploys)

A ready-to-run deploy.sh is in this directory.

Caveats

• SAM.gov award history is exposed via the opportunities API filtered to ptype=a (Award Notice). For deeper award analytics (CFDA-level totals, recipient rollups), USAspending.gov is more appropriate and would be a v2 add.
• Cache TTL is global (24h). For deadline-sensitive flows the agent should pass distinct query args or call /admin/keys to mint a key that bypasses cache (not yet exposed — see TODO).
• Match scoring is deterministic Jaccard over title + agency tokens. It's fast and free; an LLM rerank can be added behind the same interface.
• Stripe wiring is one-way (/billing/upgrade). The MCP server doesn't host the checkout page itself — that lives on the marketing site.
