An MCP server for querying [Apache AGE](https://age.apache.org/) graphs in PostgreSQL.
Homebrew Age MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. An MCP server for querying Apache AGE graphs in PostgreSQL.
The server ships on PyPI as age_mcp_server, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Once Homebrew Age is connected, these are the calls the assistant has available:
read-age-cypher — Run a validated, parameterized, paginated read-only Cypher querylist-age-graphs — List Apache AGE graphsget-age-schema — Inspect counts, directions, and sampled property typeswrite-age-cypher — Run Cypher containing a mutating clausecreate-age-graph — Create a graphdrop-age-graph — Permanently drop a graphYou will need 2 environment variables: PG_CONNECTION_STRING, PGPASSWORD. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of database access servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Homebrew Age's toolset — read-age-cypher, list-age-graphs, get-age-schema and 3 more — is a fair guide to whether it matches your workflow. It is maintained by rioriost; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
