## Tools
- GetTopOperations - 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` must be at least 6 hours before now), plus an optional limit (default 50). This report is rate limited. Endpoint: https://mcp.apollographql.com
- GetPersistedQueryListStatus - 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. Endpoint: https://mcp.apollographql.com
- GetLaunchHistory - 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launches for a graph variant (most recent first) to detect deployment instability such as repeated failures or frequent superseded launches.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 assess deployment stability. Provide the graph ID, variant name, and optionally a limit (default 20 most recent launches, max 100 per page) and an offset to page further back. Endpoint: https://mcp.apollographql.com
- ApolloConnectorsSpec - Returns the Apollo Connectors specification for guidance on creating or modifying GraphQL schemas that use @connect or @source. Endpoint: https://mcp.apollographql.com
- GetLaunch - 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 Use to drill into a specific launch — e.g. a failed or superseded one found via GetLaunchHistory (pass its id here).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 launch ID. Endpoint: https://mcp.apollographql.com
- GetSubgraphMetrics - 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 `orderBy` descending: default FETCH_COUNT (busiest); use FETCH_WITH_ERRORS_COUNT for most error-prone, FETCH_LATENCY_P99_MS for slowest. Rows are per-DAY buckets, so for a multi-day window sum a column per subgraph to get the window total. `variantName` optionally scopes to one or more variants (omit for all). `subgraphName` optionally scopes to one or more subgraphs by exact name (omit for all); pattern/substring matching is not supported. Note: `to` must be at least 1 day in the past (DAY resolution). Endpoint: https://mcp.apollographql.com
- GetMyIdentity - 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 does not have to supply either. Also handles user keys (memberships) and service-account keys. Endpoint: https://mcp.apollographql.com
- ApolloDocsRead - Reads an Apollo documentation page by slug in chunks. Use slugs returned by ApolloDocsSearch. Endpoint: https://mcp.apollographql.com
- GetOperationMetrics - 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` descending: default REQUEST_COUNT (busiest); use REQUEST_WITH_ERROR_COUNT for most error-prone, REQUEST_LATENCY_P99_MS for slowest. Rows are per-DAY buckets, so for a multi-day window sum a column per operation to get the window total. `variantName` optionally scopes to one or more variants (omit for all). Note: `to` must be at least 1 day in the past (DAY resolution). Endpoint: https://mcp.apollographql.com
- GetLatestLaunch - 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 schema changes. Also returns the latest approved launch for comparison. Provide the graph ID and variant name. Endpoint: https://mcp.apollographql.com
- GetVariantDetails - 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 compliance. Provide the graph ID and variant name (e.g., "production"). Endpoint: https://mcp.apollographql.com
- ApolloDocsSearch - Searches official Apollo documentation for GraphQL, GraphOS, Apollo Router, Apollo Client, MCP Server, schema design, deployment, and Connectors. Returns URLs, slugs, and excerpts. Endpoint: https://mcp.apollographql.com
- GetLintResults - 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 a limit (default 5 most recent check workflows). Endpoint: https://mcp.apollographql.com
