A tool for inspecting a ROS 2 system, where ROS 2 is software used to connect parts of robots. It can inspect topics, nodes, services, coordinate transforms, and actions in simulated or live mode.

Use it to inspect ROS 2 topics, nodes, services, transforms, and actions, or to run the included mock demonstration. It can also serve these functions through MCP.

It gives an agent a way to examine how a robot software graph is connected and behaving.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00066	$0.00313
Opus 5.5	$0.00026	$0.00125
Sonnet 5.5	$0.00013	$0.00063
Haiku 4.5	$0.00007	$0.00031

Measured 2mo ago against content hash 5c6b16a7219e, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

ros2-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
