Remove a subgraph from a variant and start composition, the same write that `rover subgraph delete` performs. Returns the composition errors that the removal causes. This deletes the subgraph from the…
List past schema checks for a graph: each check's ID, status, timestamps, the subgraph it checked, the variant it ran against, the commit, and the status of each task in the check, plus the total coun…
Check whether a graph variant has a Persisted Query List (PQL), and return its ID, its name, and its current build (revision and operation count). Pass the ID to PublishPersistedQueries. Use to assess…
Read the composed supergraph schema (SDL) for a graph variant, with the composition ID and any composition errors. This is the same read that `rover supergraph fetch` performs. A supergraph schema is …
Reads an Apollo documentation page by slug in chunks. Use slugs returned by ApolloDocsSearch.
Read the outcome of one schema check run: the overall status, and for each task in the run the composition errors, lint diagnostics, schema changes with the client operations they affect, downstream v…
Searches official Apollo documentation for GraphQL, GraphOS, Apollo Router, Apollo Client, MCP Server, schema design, deployment, and Connectors. Returns URLs, slugs, and excerpts.
Validate client GraphQL operations against a variant's published schema and return each problem's type (FAILURE, WARNING, INVALID), code, description, and the name of the operation it came from. This …
Create or update a contract variant and start a launch for it, the same write that `rover contract publish` performs. A contract variant is a filtered view of another variant's schema, built by includ…
Replace the README of a graph variant, the same write that `rover readme publish` performs. The README is the Markdown document shown on the variant's page in GraphOS Studio. The new text replaces the…
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/deprecatio…
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 supe…
Lint a GraphQL schema document against the graph's lint rules and return each diagnostic's coordinate, severity level, message, rule, and source location, plus the error, warning, total, and ignored c…
Returns the Apollo Connectors specification for guidance on creating or modifying GraphQL schemas that use @connect or @source.
Retrieve schema lint violations from a graph's most recent schema checks: each diagnostic's coordinate, severity level, message, rule, and source location, plus error/warning/total/ignored counts. Use…
Read the filter configuration of a contract variant: the tags it includes, the tags it excludes, the source variant it is built from, and a human-readable description of the configuration. This is the…
Traffic broken down by client for a graph over a time window, as compact CSV. Columns: start timestamp, end exclusive timestamp, client name, client version, operation name, request count, request lat…
Start a schema check of a proposed schema against a variant, the same check that `rover graph check` starts. Use this for a monograph or for a whole supergraph schema; use RunSubgraphCheck for one sub…
Publish a schema to a graph variant, the same write that `rover graph publish` performs. Use this for a monograph; use PublishSubgraph for one subgraph of a federated graph. Returns a result code, whe…
Publish a subgraph schema to a variant and start composition, the same write that `rover subgraph publish` performs. Returns whether the subgraph was created or updated, any composition errors, and th…
Delete a graph, the same write that `rover graph delete` performs. This is a soft delete: the data is not removed permanently and Apollo support can restore the graph. Every variant of the graph stops…
Read one subgraph's published schema (SDL) from a variant, with its routing URL, revision, and last update time. This is the same read that `rover subgraph fetch` performs. Read one subgraph at a time…
Top subgraphs/connectors by traffic/health for a graph over a time window, as compact CSV. Columns: start timestamp, end exclusive timestamp, fetch service name, fetch count, fetch latency p50 ms, fet…
Retrieve metadata for a graph variant: its identifier, federation version, the URL of its GraphQL endpoint, and its subgraph inventory (names only). Use this to assess a variant's composition setup, s…
Top operations by usage/health for a graph over a time window, as compact CSV. Columns: start timestamp, end exclusive timestamp, operation name, request count, request latency p50 ms, request latency…
Start a schema check of one proposed subgraph schema against a variant, the same check that `rover subgraph check` starts. The check runs in the background, so this returns a workflow ID and a Studio …
Read the README of a graph variant, with the time it was last updated and who updated it. This is the same read that `rover readme fetch` performs. The README is the Markdown document shown on the var…
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, …
Resolve the caller's identity from their API key or OAuth token. 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:…
Read the schema (SDL) that is currently published to a graph variant, with its hash and publication time. This is the same read that `rover graph fetch` performs. The response holds the whole document…
Publish operations to a persisted query list, the same write that `rover persisted-queries publish` performs. A persisted query list is the set of operations a router accepts when it is configured to …
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 finding…
