Nothing serious here today

Today is the operative word: we check Impact Plexus every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 4

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

funder

funder_profile

Return one funder's plain-language profile, computed from active global observations. Each fact carries its public source name and the date it was last verified.

funder_search

Find funders by jurisdiction, cause area, size band and region. Results are ordered by how much each funder has given toward the requested cause and region in its recent public filings: larger, steadier and more widely giving funders first; funders that give mostly to one recipient or to their own related organizations, and donation platforms that pass donors' directed gifts through, come later; ties by name, then slug. This orders public giving records; it is not a fit assessment for any organization. Use the slug of a result with funder_profile to read the full profile.

opportunity

opportunity_detail

Return one opportunity: plain-language eligibility, deadline, and a link to the funder's own page.

opportunity_search

Find open and upcoming opportunities by jurisdiction, cause area, region and deadline. Ordered by deadline (soonest first, rolling and unknown deadlines last), then name, then slug. Results are not ranked against an organization. Use the slug of a result with opportunity_detail.

Impact Plexus — questions

Answers built from our own checks of this server.

What can Impact Plexus do?

It exposes 4 tools, read directly from the server on our last check. Among them: funder_profile, funder_search, opportunity_detail, opportunity_search. 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 →

What is Impact Plexus mostly used for?

Its tools cluster around funder and opportunity. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Impact Plexus working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 168 ms. The bar chart above shows every period we have measured.

How do I connect Impact Plexus?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Impact Plexus need an API key?

No. Impact Plexus completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Impact Plexus?

It answers our handshake in 168 ms on average, which is faster than 81% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
