+## Why
+
+The current MCP server provides dedicated tools for member management (`list_members`, `get_member`, `create_member`, `update_member`). While these work well for basic operations, they are limited for complex tasks that require:
+- Flexible querying with custom field selection
+- Complex filters or relationships (future)
+- Ad-hoc data exploration by AI agents
+- Leveraging GraphQL's full introspection capabilities
+
+AI agents connected via the MCP server should be able to discover the GraphQL schema dynamically and construct their own queries for complex tasks.
+
+## What Changes
+
+- Add `get_graphql_schema` tool to expose the complete GraphQL schema via introspection
+- Add `execute_graphql_query` tool to allow AI agents to execute arbitrary GraphQL queries and mutations
+- Update README.md with documentation for the new tools
+- Keep existing dedicated member tools for backward compatibility and simple operations
+
+## Impact
+
+- Affected specs: `mcp-integration`, `graphql-api`
+- Affected code: `src/mcp_server.py`, `README.md`
+- Breaking changes: None (additive only)
+- The dedicated member tools remain available, providing a simpler interface for common operations
+- AI agents gain flexibility to handle complex queries without requiring new dedicated tools
