GraphOS MCP Tools

Inspect a single launch by ID for full detail: status, timestamps, which subgraphs changed, composition errors, and the schema diff summary. Use to drill into a specific launch — e.g. a failed or superseded one found via GetLaunchHistory (pass its id here). Provide the graph ID, variant name, and la

Top subgraphs/connectors by traffic/health for a graph over a time window, as compact CSV (header row + one row per subgraph per day). Columns: start timestamp, end exclusive timestamp, fetch service name, fetch count, fetch latency p50 ms, fetch latency p99 ms, fetch with errors count. Ranked by `o

Top operations by usage/health for a graph over a time window, as compact CSV (header row + one row per operation per day). Columns: start timestamp, end exclusive timestamp, operation name, request count, request latency p50 ms, request latency p99 ms, request with error count. Ranked by `orderBy`

Resolve the caller's identity from their API key. Call this FIRST when the user asks about "my graph" but has not provided a graph ID. For a graph/service key, `me` resolves to a Graph: use `id` as the graphId and `variants[].name` as the variant for the graph-scoped health-check tools, so the user

Searches official Apollo documentation for GraphQL, GraphOS, Apollo Router, Apollo Client, MCP Server, schema design, deployment, and Connectors. Returns URLs, slugs, and excerpts.

Returns the Apollo Connectors specification for guidance on creating or modifying GraphQL schemas that use @connect or @source.

Reads an Apollo documentation page by slug in chunks. Use slugs returned by ApolloDocsSearch.

Check whether a graph variant has a Persisted Query List (PQL) and its current build (revision and operation count). Use to assess PQL configuration — a production variant with no PQL is a security gap. Provide the graph ID and variant name.

Inspect the most recent launch for a graph variant: status, completion time, subgraph changes, composition errors, and a schema diff summary vs the previous launch (additions/removals/edits/deprecations plus affected operations). Use to assess schema composition health and the impact of recent schem

Retrieve detailed metadata for a graph variant: federation version, subgraph inventory (names), router status and any pending router version, and the current router configuration (raw YAML). Use this to assess a variant's health — router config gaps, subgraph inventory, and federation version compli

Retrieve schema lint violations from a graph's most recent check workflows: each diagnostic's coordinate, severity level, message, rule, and source location, plus error/warning/total/ignored counts. Use to assess schema quality and naming/best-practice violations. Provide the graph ID and optionally

Identify the most-used operations on a graph variant for a time range, with request counts, types, and signatures. Use to find high-traffic operations, detect unused operations, and prioritize findings by traffic impact. Provide graph ID, variant, and a from/to time range (ISO 8601 timestamps; `to`

Retrieve recent launches for a graph variant (most recent first) to detect deployment instability such as repeated failures or frequent superseded launches. Each entry includes the launch id, status, and timestamps, so you can identify a specific launch and drill into it with GetLaunch. Use to asses
