+## 1. Setup
+
+- [x] 1.1 Create git worktree for feature branch
+- [x] 1.2 Verify GraphQL API introspection is enabled (should be default in Strawberry)
+
+## 2. Implementation
+- [x] 2.1 Add `get_graphql_schema` tool to MCP server
+  - Add introspection query constant
+  - Implement tool handler that executes introspection
+  - Format schema response as readable text
+  - Add tool to list_tools() handler
+- [x] 2.2 Add `execute_graphql_query` tool to MCP server
+  - Add tool definition with query and variables parameters
+  - Implement tool handler that executes arbitrary queries
+  - Format query results as JSON
+  - Add proper error handling for invalid queries
+  - Add tool to list_tools() handler
+
+## 3. Testing
+- [x] 3.1 Test `get_graphql_schema` tool
+  - Verify introspection returns complete schema
+  - Test error handling when API is unavailable
+- [x] 3.2 Test `execute_graphql_query` tool
+  - Test simple query execution (e.g., list members)
+  - Test query with variables (e.g., get member by ID)
+  - Test mutation execution (e.g., create member)
+  - Test error handling for invalid queries
+  - Test error handling for validation errors
+
+## 4. Documentation
+- [x] 4.1 Update README.md
+  - Add section for new GraphQL tools
+  - Document `get_graphql_schema` tool usage
+  - Document `execute_graphql_query` tool with examples
+  - Explain when to use general tools vs dedicated member tools
+- [ ] 4.2 Add usage examples
+  - Example: Discover schema with AI agent
+  - Example: Execute custom query
+  - Example: Execute query with variables
+
+## 5. Integration
+- [x] 5.1 Verify backward compatibility
+  - Ensure existing dedicated tools still work
+  - Test that MCP server starts successfully
+- [x] 5.2 Manual testing with MCP client
+  - Test schema retrieval via MCP
+  - Test query execution via MCP
+  - Verify formatted output is readable
+
+## 6. Finalization
+- [x] 6.1 Run code formatting (Black, isort, ruff)
+- [x] 6.2 Review changes for simplicity
+- [x] 6.3 Commit changes with conventional commit message
+- [x] 6.4 Remove worktree after merge
