AI agents call get_graphql_schema to retrieve information from Pointsyeah without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
get_graphql_schema is purely informational—it queries and returns metadata about a GraphQL API's structure and capabilities. It has no side effects, creates no data, executes no operations, and performs no mutations. The description emphasizes it is meant for discovery before constructing queries, confirming it is a read-only introspection tool.
From the tool's definition The tool 'Returns a summary of the AppSignal GraphQL API schema' and is explicitly labeled as 'This is a discovery tool' that 'provides' information about available Query fields, Mutation fields, and type definitions.

Returns a summary of the AppSignal GraphQL API schema, including available Query fields, Mutation fields, and all type definitions with their names, kinds, and descriptions. This is a discovery tool - use it BEFORE constructing a custom_graphql_query to understand what data is available. The summary provides: - Query fields: What data you can fetch (app, organization, viewer, timezones) - Mutation fields: What actions you can perform - Types: All available types with their kind (type/input/enum/interface/union/scalar) and field counts After reviewing this summary, use get_graphql_schema_details with specific type names to see full field definitions before writing your query. IMPORTANT: Prefer using the other specialized tools (get_exception_incident, search_logs, get_metrics, etc.) for common operations. Only use custom GraphQL queries when: - The specialized tools don. It is categorised as a Read tool in the Pointsyeah MCP Server, which means it retrieves data without modifying state.
Register the Pointsyeah MCP server in PolicyLayer and add a rule for get_graphql_schema: 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 Pointsyeah. Nothing to install.
get_graphql_schema is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_graphql_schema 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 get_graphql_schema. 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.
get_graphql_schema is provided by the Pointsyeah MCP server (slack-workspace-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
