What is mcp-probe-kit?

A routing guide for choosing mcp-probe-kit tools based on what the user wants to do. MCP is a way for an agent to call configured external development tools.

Use it to select tools for starting a feature or bug fix, inspecting code, running a workflow, or generating a commit.

It reduces uncertainty about which tool to call before writing code when mcp-probe-kit is configured.

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	$0.00083	$0.01727
Opus 5.5	$0.00033	$0.00691
Sonnet 5.5	$0.00017	$0.00345
Haiku 4.5	$0.00008	$0.00173

Security

Grade A, and why

mcp-probe-kit 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.
