funder_search — Search public funders
Advertised by the server during the last successful anonymous check.
Advertised read-only

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.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http impact-plexus-mcp https://mcp.impactplexus.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add impact-plexus-mcp --url https://mcp.impactplexus.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable impact-plexus-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "impact-plexus-mcp": {
      "url": "https://mcp.impactplexus.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "impact-plexus-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.impactplexus.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start impact-plexus-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "impact-plexus-mcp": {
      "type": "http",
      "url": "https://mcp.impactplexus.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http impact-plexus-mcp https://mcp.impactplexus.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "impact-plexus-mcp": {
      "url": "https://mcp.impactplexus.com/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "impact-plexus-mcp": {
      "serverUrl": "https://mcp.impactplexus.com/mcp"
    }
