# HugeGraph Operator ## Tool Routes | Goal | Tool | | --- | --- | | Quick check connection, status, MCP read-only state | `inspect_graph_tool(include_raw_schema=false)` | | Fetch vertex/edge counts | `inspect_graph_tool(include_counts=true)` | | Inspect full schema, primary keys, indexes, edge endpoints | `inspect_graph_tool(include_raw_schema=true)` | | Check readonly, graph, or graphspace | `inspect_graph_tool(include_raw_schema=false)` | | Verify whether graph data exists | `query_graph_data_tool` (bounded page or exact ID query) | | Get schema context before query | `inspect_graph_tool(include_raw_schema=true)` | | Check schema before import | `inspect_graph_tool(include_raw_schema=true)` | | Check schema before schema design | `inspect_graph_tool(include_raw_schema=true)` | | Check AI generation readiness | `inspect_graph_tool(include_raw_schema=false)`, then optionally `generate_gremlin_tool(query, execute=false)` | `inspect_graph_tool` reports `hugegraph_ai_status`, but does not expose the `HUGEGRAPH_MCP_ALLOW_AI` or `HUGEGRAPH_MCP_ADMIN_MODE` configuration values. Check those environment variables in the server process when diagnosing a disabled AI call or an admin-gated tool. ## Order ```text Status check: inspect_graph_tool Schema audit: inspect_graph_tool(include_raw_schema=true) Data verification: inspect_graph_tool(include_counts=true) -> query_graph_data_tool ``` When AI is disabled by configuration, `hugegraph_ai_status="disabled"` is normal; no AI service check is needed. `unavailable` means an enabled AI service check failed. Structured query and plan lifecycle tools require the default `core` toolset. For a `legacy` deployment, enable `HUGEGRAPH_MCP_TOOLSET=core` and restart before using them. These skills describe the current release with `core` / `legacy`. The previous `1.7.1` release uses `v2_core` / `v1`; see the [migration guide](../../hugegraph-mcp/README.md#toolset-naming-and-migration).
