Execute GraphQL operations (queries and mutations) against the federated system. WARNING: This tool performs remote operations. 'Mutation' operations will modify persistent state; execute these only when a state change is intended. Prerequisites: Verify schema structure using 'introspect-schema' before executing complex queries. Security: Inherits environment-based authentication. Returns: A JSON object containing the execution result ('data') or a list of 'errors' in case of failure.

Parameter	Type	Description
`query`	string	The GraphQL query or mutation string. Example: 'query { guilds { id name } }'.
`headers`	string	JSON stringified object of extra HTTP headers for the request.
`endpoint`	string	Optional target GraphQL HTTP/HTTPS URL to dynamically switch endpoint before execution.
`variables`	string	JSON stringified object of variables. Example: '{"id": "123"}'.

Retrieve GraphQL schema details or system manifest. READ-ONLY: Non-destructive metadata discovery. Usage: 1. If 'typeNames' is provided: Returns the full SDL (Schema Definition Language) for the requested types, including fields and relations. 2. If 'typeNames' is omitted: Returns a Federated Manifest—a high-level summary of connected nodes, their capabilities, and available domain entities (not the full schema). Use this to navigate the federated graph topology before executing queries.

Parameter	Type	Description
`headers`	string	JSON stringified object of extra HTTP headers for the introspection request (e.g. '{"Authorization": "Bearer token"}').
`endpoint`	string	Optional target GraphQL HTTP/HTTPS URL to dynamically switch endpoint before execution.
`typeDepth`	number	Depth of nested fields to retrieve (default: 2)
`typeNames`	string	List of specific GraphQL type names to introspect. If provided, returns the detailed SDL definitions for these types. If omitted, returns a system-wide Federated Manifest overview.
