About
MCP server providing tools to verify task completion (tests pass and changes match claim) and confirm bug reproduction before fixing.
README
Proof-of-production tools for AI coding agents — the core Fleet of One discipline as callable MCP tools. Make "done" earn itself.
Two tools, one job: stop trusting an agent's word for it.
| Tool | What it does |
|---|---|
verify_done |
Runs your test command and, in a git repo, diffs the actual changes. Returns PASS only if tests pass (exit 0) and every claimed change is really there. The gate between "agent says done" and "I believe it." |
check_repro |
Bug-first discipline: runs a command you expect to fail and confirms it actually fails, so you've reproduced the bug before you start fixing it. |
It only ever runs the command you pass, in the directory you specify. No network, no file changes of its own. Local stdio server.
Install
npm install
npm run build
npm test # end-to-end smoke test against the built server
Use it with Claude Code
Add to your MCP config (e.g. .mcp.json in your project, or the global config):
{
"mcpServers": {
"fleet-of-one": {
"command": "node",
"args": ["/absolute/path/to/fleet-of-one-mcp-server/dist/index.js"]
}
}
}
Then an agent can call verify_done before claiming a task is complete:
verify_done(test_command="npm test", expect_changed=["src/auth.ts"], claim="wired up login")
→ PASS / FAIL with the test exit code, the real git changes, and the evidence tail.
