Apollo GraphOS MCP server
Work with GraphQL schemas and graphs in GraphOS. Run by Apollo.
Fetch supergraph and subgraph schemas, publish schemas and readmes, create proposals and manage graphs in Apollo GraphOS. Most tools need a GraphOS API key passed as an argument.
Access: No sign-in needed. Vendor documentation
Server address: https://mcp.apollographql.com/mcp
Use it through the gateway
Nothing to set up. Connect the Smart Gateway once; when your assistant searches for something Apollo GraphOS does, the first call connects Apollo GraphOS to your account and runs it. You can also connect it with one click from the dashboard.
A third-party server: Apollo's terms apply, and its tool descriptions are text in front of your assistant. Connect only servers you trust.
Its 48 tools
| Tool | What it does |
|---|---|
GetGraphArtifactTags | List the graph artifact tags on a graph and the artifact each tag points to: the artifact's ID, digest, status, creation time, and variant. GraphOS Router can fetch an artifact by tag name instead of by digest. It is … |
LintSchema | 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 counts. This is th… |
DeleteApiKey | Delete an API key from an organization, the same write that `rover api-key delete` performs. This cannot be undone, and every client that uses the key stops authenticating. Returns the deleted key's ID. Provide the or… |
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 … |
PublishPersistedQueries | 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 reject anything e… |
GetProposals | List the schema proposals on a graph: each proposal's ID, title, status (DRAFT, OPEN, APPROVED, IMPLEMENTED, CLOSED), timestamps, author, the source variant it proposes changes to, and the proposal variant that holds … |
PublishReadme | 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 whole README, so… |
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 impa… |
GetSupergraphSchema | 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 the single schema… |
RunSchemaCheck | 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 subgraph. The check … |
DeleteSubgraph | 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 variant and can … |
RunSubgraphCheck | 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 URL, not a result… |
AddProposalComment | Add a comment to a schema proposal, the same action as commenting in GraphOS Studio. With no other options, the comment is a general comment on the proposal. To comment on one change, pass the schema coordinate (for e… |
PublishGraphSchema | 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, whether the publish … |
RenameApiKey | Rename an API key in an organization, the same write that `rover api-key rename` performs. The key value and its access do not change. Returns the key's ID and new name. Provide the organization ID, the key ID, which … |
ReviewProposal | Approve or reject a revision of a schema proposal, with an optional comment, the same action as Review in GraphOS Studio. Only a requested reviewer can review, and calling this again replaces the caller's earlier revi… |
GetGraphArtifact | Fetch a graph artifact by its digest, the same lookup that `rover graph-artifact fetch --digest` performs. A graph artifact is the build output, such as the composed supergraph schema, that GraphOS Router fetches from… |
GetSchemaChecks | 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 count for the filter.… |
GetSubgraphMetrics | 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, fetch latency p99 ms… |
DeleteGraph | 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 serving, so conf… |
GetVariantDetails | 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, such as subgraph i… |
PublishProposalRevision | Save a new revision of a schema proposal by publishing changed subgraph schemas to its proposal variant, the same action as Save revision in GraphOS Studio. GraphOS composes the proposal variant, records the diff agai… |
UpdateProposalStatus | Change the status of a schema proposal, the same action as the status menu in GraphOS Studio. DRAFT is for work in progress, OPEN asks reviewers to review, and CLOSED abandons the proposal. GraphOS accepts APPROVED on… |
GetLintResults | 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 to assess schema… |
GetContractConfig | 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 same read that `… |
GetPersistedQueryListStatus | 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 PQL configuratio… |
GetClientMetrics | 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 latency p50 ms, requ… |
CreateApiKey | Create an API key for an organization. The response contains the new key's value in token. It is a live credential, so give it to the user to store in a secret manager, and do not repeat it, log it, or pass it to anot… |
GetSubgraphSchema | 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: a whole supergr… |
TagGraphArtifact | Assign a tag to a graph artifact, the same write that `rover graph-artifact tag` performs. If the tag does not exist, it is created. If it exists, it moves to this artifact, and any router that fetches by that tag rec… |
ApolloConnectorsSpec | Returns the Apollo Connectors specification for guidance on creating or modifying GraphQL schemas that use @connect or @source. |
ApolloDocsSearch | Searches official Apollo documentation for GraphQL, GraphOS, Apollo Router, Apollo Client, MCP Server, schema design, deployment, and Connectors. Returns URLs, slugs, and excerpts. |
GetProposal | Read one schema proposal by its ID: title, description, status, author, the source variant, and the proposal variant with the ID of its latest launch. Also returns the latest revision (its ID, summary, schema check, a… |
GetApiKeys | List the API keys and client-credential pairs of an organization. For each key: its ID, name, type, creation, expiry, last use, revocation time, and the resources it can access. For each client-credential pair (an OAu… |
PublishSubgraph | 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 the launch that sta… |
GetGraphSchema | 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 and is not trunc… |
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 … |
GetReadme | 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 variant's page in Gr… |
GetOperationMetrics | 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 p99 ms, request … |
ApolloDocsRead | Reads an Apollo documentation page by slug in chunks. Use slugs returned by ApolloDocsSearch. |
GetCheckResults | 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 variant results, a… |
GetOfflineLicense | Fetch the offline Enterprise license for the organization that owns a graph, the same data that `rover license fetch` returns. The license is a signed JWT that lets GraphOS Router enable Enterprise features while it r… |
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, s… |
GetMyIdentity | 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: use `id` as the … |
CreateProposal | Create a schema proposal against a source variant, the same action as Create proposal in GraphOS Studio. GraphOS creates a proposal variant that starts as a copy of the source variant's schema, and the proposal starts… |
UntagGraphArtifact | Delete a graph artifact tag from a graph, the same write that `rover graph-artifact untag` performs. The tag and its full history are removed, and any router that fetches by that tag can no longer resolve it. The arti… |
PublishContract | 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 including and excluding… |
ValidateOperations | 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 is the same check… |
