Standardized env var names. |\n| `connection` | DSN building, the pool's lifetime, `ensure_graph`, `run_query` and `read_page`. *(needs the `db` extra)* |\n| `safety` | `quote_identifiers`, which keeps the case of a label a model wrote. |\n| `results` | A result as JSON a model can read: `rows_of` / `mapping_rows`, `value_sanitize`, `fit_rows`. |\n| `transport` | One `run_server` for stdio / Streamable HTTP / SSE with CORS + TrustedHost middleware. |\n\nNothing is re-exported from the package root; each server imports the module it needs, which\nis what keeps the DB-less data-modeling server from importing psycopg to read a namespace out\nof the environment.\n\n## What the pool is told once\n\nThe graph to read, how long a statement may take, and how many connections there may be. All\nthree were per call before, and the first two were a round trip each: a read tool call is 5.00\nclient-to-server flushes now against 6.00. The graph has to exist before the pool opens, since\neach connection selects it as it is made — `ensure_graph(dsn, name)` is that, on a connection\nof its own.\n\n`AGENSGRAPH_POOL_MIN_SIZE` and `AGENSGRAPH_POOL_MAX_SIZE` are how the size is found. Both ends\nare given values on purpose: a pool told only the lower one is that wide at the top as well,\nand…","publisher":null,"homepage":"https://github.com/skaiworldwide-oss/agensgraph-ai/tree/main/mcp-agensgraph","repository":"https://github.com/skaiworldwide-oss/agensgraph-ai/tree/main/mcp-agensgraph","version":"0.3.1","license":null,"protocols":["mcp"],"tags":["agensgraph","graph","mcp","model","context","protocol"],"pricing":null,"endpoints":[{"url":"pypi:mcp-agensgraph-common","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi"}},"derived":{"capabilities":[{"slug":"knowledge.knowledge-graph","name":"Knowledge Graphs","confidence":1,"provenance":"declared"}],"categories":["knowledge"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"mcp-agensgraph-common","registry":"pypi","observedAt":"2026-10-28T09:23:14.106Z","publishedAt":"2026-09-23T20:14:20.859946Z","latestVersion":"0.3.1"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"mcp-agensgraph-common","url":"https://pypi.org/project/mcp-agensgraph-common/","firstSeenAt":"2026-09-10T00:23:14.339Z","fetchedAt":"2026-10-28T09:22:23.268Z","normalizedAt":"2026-10-28T09:22:23.268Z"}]},"firstSeenAt":"2026-09-10T00:23:14.339Z","updatedAt":"2026-10-28T09:23:14.106Z"}
