GrantCue

Overview

GrantCue is a Model Context Protocol server that lets you search public US grants and foundation profiles directly from IRS filings. It's read-only and requires no sign-in, making it straightforward to integrate into your workflow. Instead of switching between apps and copying data by hand, your AI assistant can call GrantCue as a native tool.

GrantCue runs as a remote hosted service at https://www.grantcue.com/api/v1/mcp, so there's nothing to install locally. Just point your MCP client to that endpoint and you're ready to go. The latest release is v2.0.0, and the service requires no authentication.

GrantCue is listed in the File System category on mcp.site and works with any MCP client, including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain GrantCue, claim this listing to verify ownership and keep information up to date.
