## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 840 tokens (~210/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `search_grants` (~321 tokens)

Search grants

Search the public GrantCue grant catalog (federal, state, local and foundation opportunities) with the same filters as the Discover page. Returns a short page of matches, at most 25, and can reach the first 100 results of a search. Grant text is provided by the funders.

Input parameters:

- `agency` (string): Funding agency or organization (partial match).
- `applicant_type` (string): Who is applying. Grants that exclude this kind of applicant are left out.
- `category` (string): Funding category.
- `due_in_days` (integer): Only grants closing within this many days.
- `location` (string): A place page slug such as "allegheny-county-pa" to limit results to grants open there.
- `max_funding` (number): Largest award or total, in US dollars.
- `min_funding` (number): Smallest award or total, in US dollars.
- `offset` (integer): Skip this many results, to page through. Only the first 100 results of a search can be reached.
- `page_size` (integer): Results per page. Default 10.
- `query` (string): Keywords, an opportunity number, or a quoted phrase.
- `sort` (string): relevance = best match for the query, due_soon = closing soonest, newest = most recently opened. Default: relevance when there is a query, otherwise due_soon.
- `status` (array): posted = open for applications now, forecasted = announced but not yet open. Default: both.

### `get_grant` (~58 tokens)

Get a grant

One public catalog grant in full: dates, amounts, eligibility, and links to the funder’s own pages. A grant that is not publicly listed is not found.

Input parameters:

- `grant_id` (string, required): The grant id from search_grants.

### `search_funders` (~209 tokens)

Search foundations

Search the foundations that have a public GrantCue profile (built from the latest Form 990-PF, or Form 990 Schedule I for community foundations and other grantmaking charities), largest givers first. Search by name, city, state or EIN, by the state they mainly give to, or for those that publish how to apply. Form 990 grantmakers are found by name, state or EIN, after the 990-PF matches, each marked source_form "990". Returns 10 per page.

Input parameters:

- `accepting_applications` (boolean): true: only foundations whose latest filing publishes how to apply.
- `page` (integer): Page of 10 results. Only the first 10 pages can be reached.
- `query` (string): A foundation name, the city or state it is based in, or its 9-digit EIN.
- `recipient_state` (string): Foundations whose giving goes mostly to this state (two-letter code), like the state lists on the foundations pages.

### `get_funder` (~164 tokens)

Get a foundation

A foundation’s public GrantCue profile, from the latest Form 990-PF, or Form 990 Schedule I for community foundations and other grantmaking charities: giving totals, typical and median grant, giving by year, where it gives, the 25 largest grants its latest filings report, and for a 990-PF filer how to apply. For a Form 990 funder: its kind, the latest tax year, totals and the top 10 recipients (yearly totals); Form 990 does not say whether it accepts applications. Only foundations with a public profile, and funders with a Schedule I return, are found. It never returns the full list of reported grants.

Input parameters:

- `ein` (string, required): The foundation’s EIN, with or without the dash.

## Common questions

### What is the GrantCue MCP server?

GrantCue is an MCP server listed in the public MCP registry as com.grantcue/grantcue. Search public US grants and foundation profiles from IRS filings. Read-only, no sign-in. This page covers its hosted endpoint (https://www.grantcue.com/api/v1/mcp).

### Is the GrantCue MCP server safe to use?

GrantCue scores 76 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the GrantCue MCP server expose?

GrantCue exposes 4 tools: search_grants, get_grant, search_funders, get_funder. Their descriptions and schemas cost roughly 752 tokens of context every time the server is loaded.

### Does the GrantCue MCP server require authentication?

No. We connected to GrantCue without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the GrantCue MCP server still maintained?

GrantCue is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
