AI agents use ApolloConnectorsSpec to create or modify resources in Apollo GraphQL. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call ApolloConnectorsSpec repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Apollo GraphQL.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

This tool provides the agent with the specification which describes how to use Apollo Connectors in a graphql schema to send an HTTP request or use any REST API with a graph. A user may refer to an Apollo Connector as 'Apollo Connector', 'REST Connector', or even just 'Connector'. Treat these all as synonyms for the same thing. You MUST ALWAYS call this tool to use this specification as a guide BEFORE planning, making, or proposing ANY edits or additions to a connectors schema file and/or a graphql file containing @connect or @source. This tool is to provide the agent with guidance, not the user.. It is categorised as a Write tool in the Apollo GraphQL MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Apollo GraphQL MCP server in PolicyLayer and add a rule for ApolloConnectorsSpec: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Apollo GraphQL. Nothing to install.
ApolloConnectorsSpec is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the ApolloConnectorsSpec rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for ApolloConnectorsSpec. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
ApolloConnectorsSpec is provided by the Apollo GraphQL MCP server (@modelcontextprotocol/server-apollo-graphql). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
