triage

triage is a skill for Claude Code, Codex from activeing123/mcptoon. It costs 30 tokens per session (489 once invoked), scanned A, original, Apache-2.0.

A troubleshooting guide for finding why an MCP server is not configured, starting, responding, or exposing its tools. MCP is a standard way for AI tools to connect to external servers.

In plain words
What is it for?
It helps run health checks, inspect server tools, make test calls, and diagnose issues such as missing binaries or startup timeouts.
Why use it?
It narrows a failure to the configuration, connection, or tool layer and suggests checks for common causes.

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.

Security

Grade A, and why

triage 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 yesterday.

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 it actually says

Triage MCP server failures with mcptoon

Work top-down; stop as soon as the layer with the fault is found.

1. Read the config layer first

mcptoon doctor

Catches: invalid JSON, unknown fields, missing binaries for stdio commands, malformed URLs. Fix anything reported before deeper probing.

2. Check connectivity

mcptoon health            # every server, human-readable
mcptoon health --json     # CI/CD friendly, exit 1 if any dead

3. Probe the tool layer

mcptoon list                       # is the server even registered?
mcptoon manifest --compact         # do its tools appear at all?
mcptoon inspect <server> <tool>    # full schema of one tool
mcptoon call <server> <tool> '{}' --toon   # minimal live call

list shows it but manifest does not → the server answers initialize but fails tools/list: read the server's own logs (run its command manually).

Common failures → fixes

Symptom Likely cause Fix
doctor: binary not found command not on PATH fix PATH, or install the package, or use npx/uvx
health: timeout server hangs on startup raise timeout, or fix slow startup; try running the command directly
call: unknown tool tool toggled off check the toggle on that tool in config, then mcptoon sync
call: schema error wrong args shape mcptoon inspect the tool and match the inputSchema exactly
stdio: spawn ENOENT bad command token command must be one token on PATH or ./relative; never a shell string
everything dead after edit config overwritten by hand in agent dir re-edit ~/.mcptoon/config.json, run mcptoon sync

After fixing

mcptoon sync        # push the repaired config to all agents
mcptoon health      # prove it is green
Changes

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.
