What the Benevity connector does

The Benevity MCP server connects Benevity's verified nonprofit database to Claude, ChatGPT and any MCP-compatible agent. Two read-only tools search charitable organisations by cause, keyword or location and return mission detail plus a verified website link. No account, no sign-in, and no tool that can move money.

Benevity tools (2)

  • Benevity Nonprofit Search
  • Benevity Get Nonprofit Details

Tool names from Anthropic's directory listing. This server requires sign-in, so we could not read tool descriptions or parameter schemas.

Limits

  • The vendor documentation Anthropic nominates is Anthropic's own. The directory's documentation URL points at support.claude.com, which redirects to academy.claude.com — a page written by Anthropic about its own connector. Treating it as the vendor's enumeration would have made the Reverse-Honeycomb self-referential, comparing Anthropic's directory against Anthropic's tutorial. Benevity's genuine documentation is elsewhere, in its own help centre, and is linked below. It is the richer of the two.
  • We verified nothing about the auth posture ourselves. Both parties state no authentication is needed and Anthropic's directory records the server as authless, but every request we made returned 403 before reaching the server. authVerified is therefore false: an authless claim we could not exercise is a vendor claim, not an observation.
  • No RFC 9728 descriptor exists. .well-known/oauth-protected-resource, the path-suffixed variant, and .well-known/oauth-authorization-server all returned 404 — as did a nonsense control path, so the host is not a catch-all and those 404s are real. There is no scope list because there is no OAuth.
  • We could not read tool schemas, annotations or prompts. No tools/list, prompts/list or resources/list response was obtainable. Parameter shapes and read-only labels on this page come from Benevity's prose, and the two advertised prompts are unread.
  • Ten results per search, no pagination. Benevity documents a hard cap of 10 and a query length of 3 to 180 characters, and directs users to refine terms instead of paging. A broad question cannot be exhaustively answered through this connector.
  • Cause identifiers are session-scoped. Benevity's troubleshooting states organisation identifiers only work within the current search session, so a detail lookup in a new conversation requires searching again first. Identifiers cannot be stored and reused later.
  • Results are cached, not live. Benevity states the connector uses cached data that refreshes regularly, while Anthropic's tutorial says Claude accesses the database in real time. The two descriptions conflict, and neither publishes a refresh interval.
  • No tax or financial data. Benevity states the connector returns mission information, programme descriptions and website links, and directs users to the nonprofit's site or to external resources for tax or financial detail. Do not use it to check charitable status.
  • Coverage is uneven and incomplete. Benevity states coverage is strongest for United States organisations and major international nonprofits, and that an organisation missing from results may simply not be part of the validated network yet. Absence is not evidence of illegitimacy.
  • Rate limits exist but no rate is published. Benevity says only that standard rate limits apply to prevent abuse.
  • The database size is stated four different ways across four sources, spanning two million to 2.5 million. Cite the range, not a figure.

Frequently asked questions

Can the Benevity connector donate money or direct a gift?

No. Benevity's documentation states the connector returns verified links to nonprofit websites where a person completes the donation, keeping giving within official channels. Both tools are documented as read-only and idempotent, neither takes an amount or a payment method, and no tool name carries a donate, grant or disburse verb. The agent researches; a human pays.

How many tools does the Benevity MCP server have?

Two, and both enumerations agree on that. Anthropic's directory lists Benevity Nonprofit Search and Benevity Get Nonprofit Details; Benevity's own help centre documents benevity_nonprofit_search and benevity_nonprofit_details. The names differ in casing and prefix but map one-to-one, with nothing extra on either side. Both are read-only searches over public nonprofit data.

Does the Benevity connector require a Benevity account or sign-in?

No. Benevity states you do not need a Benevity account and that no authentication is required, and Anthropic's directory records the server as authless. We could not confirm this over the wire: the endpoint returned 403 from a generic edge with no authentication challenge header, which is a network block rather than an auth posture.

What personal data does the Benevity connector send or store?

None that Benevity documents. Benevity states the connector collects no personal data, that search terms are not stored or associated with individual users, and that no personally identifiable information is shared with the MCP server. Everything returned is public nonprofit information — missions, programmes, geography and a website link.

How many search results does the Benevity connector return?

Up to ten per query, with no pagination. Benevity documents a maximum of 10 results, a query length of 3 to 180 characters, and advises refining search terms rather than paging when results miss. That cap is a real ceiling on coverage: a database Benevity sizes in the millions is reachable only ten rows at a time.

Which Claude plans can use the Benevity connector?

The two sources disagree. Anthropic's tutorial says all paid plans — Pro, Max, Team and Enterprise — and gives Team and Enterprise admin steps. Benevity's own pages say the connector is currently available for Claude Pro and to contact Anthropic about Team or Enterprise. Anthropic's page is newer, so treat the wider claim as current.

How large is Benevity's nonprofit database?

Between two and 2.5 million, depending on which source you read. Benevity's press release says more than two million validated nonprofits, Anthropic's directory says 2.3 million, Benevity's integration page says 2.4 million, and Anthropic's tutorial says 2.5 million or more. No source is dated in a way that resolves the spread.

Why does an anonymous request to the Benevity MCP endpoint return 403?

Because an edge proxy blocks it, not because the server demands credentials. The response is a 134-byte generic Forbidden page served through Google's front end, with no authentication challenge header. Every path under the same prefix returns a byte-identical body, including paths that do not exist, so the 403 carries no information about the server behind it.
