SUMO-MCP-Server

SUMO-MCP 是一个连接大语言模型 (LLM) 与 Eclipse SUMO 交通仿真的中间件。通过 Model Context Protocol (MCP)，它允许 AI 智能体（如 Claude, Cursor, TRAE等）直接调用 SUMO 的核心功能，实现从OpenStreetMap 数据获取、路网生成、需求建模到仿真运行与信号优化的全流程自动化。

// key findings
⚠️
Tool descriptions don’t match what handlers do
1 tool describes read intent but its handler mutates — get_sumo_info (line 467: result = subprocess.run()
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

manage_network

Manage SUMO network (generate, convert, or download OSM).

convert_ezdesignx_network

Convert an ezdesignX v1 JSON or JSONC intersection file into SUMO network artifacts.

manage_demand

Manage traffic demand (random trips, OD matrix, routing).

control_simulation

Control SUMO simulation (connect, step, disconnect).

query_simulation_state

Query simulation state (vehicles, speed, position). Requires active connection.

optimize_traffic_signals

Optimize traffic signals.

run_workflow

Run high-level SUMO workflows. Available workflows: **sim_gen_eval** - Generate grid network, simulate traffic, analyze results. params: - grid_number (int): Grid size NxN. Default=3. Aliases: grid_size, size - sim_seconds (int): Simulation duration in seconds. Default=100. Aliases: steps, du…

manage_rl_task

Manage RL tasks (list scenarios, custom training).

get_sumo_info

Get the version and path of the installed SUMO.

run_simple_simulation

Run a SUMO simulation using a config file.

run_analysis

Analyze FCD output.

// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.
configSUMO_HOMESUMO: [Eclipse SUMO](https://www.eclipse.org/sumo/) ( recommended; SUMO binaries should be available in PATH)
configSUMO_MCP_TRACI_TIMEOUT_S
configSUMO_MCP_MAX_OUTPUT_CHARS

Tool annotations

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

11/11 tools missing one or more hints — manage_network (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); convert_ezdesignx_network (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); manage_demand (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +8 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.

Descriptions match behaviour

1 tool describes read intent but its handler mutates — get_sumo_info (line 467: result = subprocess.run()

Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.

Tool inputs are validated

10/11 tool handlers declare input schemas (91%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

6/11 tool handlers wrap calls in try/catch (55%)

Wrap each tool handler body in try/catch and return a structured error response.

Tests exist

No test files found

Add tests that exercise each declared tool.

Tool description accuracy

get_sumo_info: description implies read-only but handler writes/deletes/executes

Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 7 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
