Age MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Age MCP directly instead of describing what you should do. Built with F# on .NET 10 -- 1,300 lines, 21 tools, zero Python dependencies.
Once Age MCP is connected, these are the calls the assistant has available:
Query — The Query tool exposed by this serverSetup 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.
You will need 4 environment variables: AGE_CONNECTION_STRING, TENANT_ID, EMBEDDING_API_URL, EMBEDDING_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Age MCP's toolset — Query — is a fair guide to whether it matches your workflow. It is maintained by neftedollar; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Age MCP's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
