A comprehensive [Model Context Protocol (MCP)](https://modelcontextprotocol.io) server that provides AI assistants with enterprise-grade access to
If you already use Charity, the charity mcp server is the piece that lets your assistant work with it directly. A comprehensive Model Context Protocol (MCP) server that provides AI assistants with enterprise-grade access to charity and nonprofit organization data from the IRS database. This feature-complete server.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Real — time charity information lookupTax — deductible status verificationPrerequisites — The Prerequisites tool exposed by this serverInstallation — 1. Clone the repository bash git clone cd charity-mcp-serverArchitecture — 1. MCP Layer: Handles protocol communication and tool registration 2. Validation Layer: Input sanitization and validation with Zod schemas 3Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Configuration is passed through the environment: CHARITY_API_KEY, CHARITY_API_BASE_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Charity's toolset — Real, Tax, Prerequisites and 2 more — is a fair guide to whether it matches your workflow. It is maintained by briancasteel; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
