Grantsgov MCP Server missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 12 min ago.

run in your terminal

This one needs environment variables set before it will start: MCP_TRANSPORT_TYPE (Selects the HTTP transport.), MCP_HTTP_HOST (The hostname for the HTTP server.), MCP_HTTP_PORT (The port to run the HTTP server on.), MCP_HTTP_ENDPOINT_PATH (The endpoint path for the MCP server.), MCP_PUBLIC_URL (Public origin override for deployments behind a TLS-terminating reverse proxy (e.g. https://mcp.example.com).), MCP_AUTH_MODE (Authentication mode to use: 'none', 'jwt', or 'oauth'.), MCP_LOG_LEVEL (Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').). The author declared them in the registry entry; get the values from the project itself.

Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

grantsgov
grantsgov_get_opportunity
Read the full Grants.gov record for up to 5 opportunities, given numeric opportunity ids or opportunity numbers: deadline and its explanation, award ceiling and floor, total funding, expected awards, cost sharing, eligible applicant types with the eligibility narrative, description, assistance listings, agency contact, NOFO attachments with download links, and application packages. An opportunity number is resolved across all statuses. A miss or an ambiguous number comes back as an unresolved entry with guidance, not an error.
grantsgov_list_reference
List the codes Grants.gov search filters accept, with labels and live opportunity counts: agencies (top level, or one agency's sub-agencies via parent_code, or matched by name via name_contains), applicant eligibility types, funding categories, funding instruments, statuses, sort options, and keyword syntax. Use the codes as grantsgov_search_opportunities inputs.
grantsgov_search_opportunities
Search federal funding opportunities on Grants.gov by keyword, agency, applicant eligibility, funding category, funding instrument, assistance listing, opportunity number, posting window (posted_within_days), or closing window (closing_within_days). Returns forecasted and posted opportunities unless statuses says otherwise, each row led by its close date and days remaining, plus facet counts for narrowing. Bare keyword terms are all required; join alternatives with OR, in parentheses when other terms stay required. Rows carry no award amounts or eligibility detail; read those with grantsgov_get_opportunity. Filter codes come from grantsgov_list_reference.

Grantsgov MCP Server — questions

Answers built from our own checks of this server.

What can Grantsgov MCP Server do?
It exposes 3 tools, read directly from the server on our last check. Among them: grantsgov_get_opportunity, grantsgov_list_reference, grantsgov_search_opportunities. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Grantsgov MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 320 ms. The bar chart above shows every period we have measured.
How do I connect Grantsgov MCP Server?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Grantsgov MCP Server need an API key?
No. Grantsgov MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Grantsgov MCP Server?
It answers our handshake in 320 ms on average, which is faster than 44% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Grantsgov MCP Server?
The npm package @cyanheads/grantsgov-mcp-server was installed 187 times in the last week. Week over week that is +164%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Grantsgov MCP Server open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 2 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
