Mcity Data Engine MCP Server
Enables natural language interaction with complex computer vision workflows such as auto-labeling, class mapping, and embedding selection through an LLM-agnostic MCP orchestration layer.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
30/30 tools missing one or more hints — configure_auto_labeling (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); set_auto_labeling_hyperparams (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); set_msight_localization_config (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +27 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Destructive tools are labelled
1 tool perform destructive updates without destructiveHint — run_data_ingest deletes at line 361 (backup_path.unlink(missing_ok=True))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Descriptions match behaviour
1 tool describes read intent but its handler mutates — detect_fisheye_intrinsics (line 109: dest.write_text(json.dumps(intrinsics, indent=2)))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool test coverage
16/30 tools referenced in tests (53%)
Write tests that reference each tool by name so every tool has at least one test.
Tool description accuracy
detect_fisheye_intrinsics: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
