doctor

A diagnostic command for checking whether the CaBrain command-line program, login, and MCP connection work. CaBrain is a memory service for AI agents.

In plain words
What is it for?
Use it when CaBrain is missing, outdated, unauthenticated, or unreachable from the agent.
Why use it?
It shows which part of the setup is broken and gives a specific command to fix failed checks.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 C, and why

doctor scanned grade C with 2 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.

What it actually says

Diagnose the CaBrain plugin setup and fix what's broken. Check, in order:

  1. CLI present — run command -v cabrain and cabrain version. If missing, tell the user to install it: npm i -g cabrain-cli (or curl -fsSL https://cabrain.fadymondy.com/install.sh | sh). The plugin's MCP server is the cabrain binary, so it must be on PATH.
  2. Up to date — compare cabrain version against the latest; if behind, suggest curl -fsSL https://cabrain.fadymondy.com/upgrade.sh | sh.
  3. Authenticated — run cabrain auth whoami. If no token/endpoint, the plugin's userConfig (api_token) may be unset — tell them to reconfigure the plugin or run cabrain auth login --token <cbt_…>.
  4. MCP live — call the brain_list tool. If it returns brains, the end-to-end path (client → cabrain mcp → API) works. If it fails with unauthorized, the token is missing or wrong.

Report each check as ✓/✗ with the exact fix command for any failure.

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.

doctor is a command published in the GitHub repository togo-framework/cabrain-cli (0 stars, last pushed 1mo ago), licensed MIT. It adds 19 tokens to every session and 301 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls).
