MCP server

Connect your AI assistant to https://mcp.impactplexus.com/mcp (Streamable HTTP). The public tools need no sign-in:

• funder_search: find funders by country, cause, province and giving size.
• funder_profile: one funder's plain-language profile, facts and sources.
• opportunity_search: open and upcoming opportunities, with deadline filters.
• opportunity_detail: one opportunity's eligibility, deadline and link to the funder's page.

All tools are read-only. Results are discovery results in a fixed order, not recommendations.
