Measures what a completed agent workflow cost to run, by reading the runtime's own session log, and submits the result to the AMI survey at survey.agentbenchmark.dev.

The cost of a single API call is easy to obtain. The cost of one finished piece of work is not: one triaged ticket, one screened CV, one drafted reply, across every call, retry and tool round-trip the agent made getting there. This measures that figure.

Every number is read from the runtime's records rather than reported by the agent. An agent asked how many tokens it has just used will estimate, and will present the estimate with confidence.

What comes back

A real run of six support tickets, triaged and answered by Claude Opus 5 in Claude Code:

Maturity Index      85.0  Strong          (observability 40%, evidence 30%, quality 30%)
Performance         78.13 Strong          confidence Very High

  quality           80.0   graded Good on ami-quality-v2
  cost              72.73  $0.123226 per ticket   ($0.739355 for the run)
  speed             84.47  20.90s per ticket
  evidence          70.0   measured, on a self-issued token
  observability    100.0

findings
  weakness  Cost is the weakest pillar at 72.73; speed is strongest at 84.47.
            $0.123226 per unit against a $0.01 reference. A cheaper model, or
            fewer calls, moves this; check calls[] for where the tokens went.

  note      Cost and speed were scored against a provisional reference, which is
            a placeholder rather than a measurement. Do not quote them as settled
            yet. The Maturity Index does not use the reference and is unaffected.

$0.12 per ticket, 21 seconds per ticket. That is the figure this exists to produce, and it is the one most teams cannot currently state about their own work.

The findings record where the scorecard's own numbers are soft. A cost reference that is still a placeholder is reported as a placeholder rather than folded into the score.

Install

There are two routes. What separates them, and what separates the hosts below, is whether anything can read your runtime's logs. That determines whether the result is recorded as measured or unmeasured.

Install the client

One block of configuration, then restart the agent.

Claude Code, in ~/.claude.json, or through the Developer settings in Claude Desktop:

{ "mcpServers": { "ami-survey": { "command": "uvx", "args": ["ami-survey"] } } }

Runs are measured: the client reads Claude Code's own session log, so the token counts and the cost come from the runtime rather than from the agent.

Codex (measured)

In ~/.codex/config.toml. Codex uses TOML here, not JSON:

[mcp_servers.ami-survey]
command = "uvx"
args = ["ami-survey"]

The client reads Codex's rollout log. This also covers a local or self-hosted model driven through Codex, because the log is written either way.

Copilot (not measured)

In .vscode/mcp.json, or your user profile through the MCP: Open User Configuration command. The key is servers here, not mcpServers:

{ "servers": { "ami-survey": { "command": "uvx", "args": ["ami-survey"] } } }

The tools work and the survey submits, but Copilot writes no session log the client can read. The run carries the workflow, the grade and the stage timings without token counts or cost, and is recorded as unmeasured.

Then, once the agent finishes a piece of work, ask it:

Take the AMI survey regarding the ticket triage you just did

There is nothing to clone and nothing to keep updated. No token needs to be supplied: the first call that requires one registers the machine and stores the token at ~/.ami-survey/token.

uvx is part of uv, the tool the MCP documentation uses for Python servers. If uv is not installed, GETTING-STARTED.md gives a pipx form and a route that requires neither.

If you already hold a token, set it as AMI_API_TOKEN in that block's env and it will be used instead of registering a new one.

Or use the remote connector, with nothing installed

In claude.ai, open Settings, then Connectors, then Add custom connector, and supply:

https://survey.agentbenchmark.dev/mcp

Nothing is installed and no token is required. These runs are recorded as unmeasured and are never compared against measured ones: a remote server cannot read your runtime's logs, so token counts and cost are absent rather than estimated.

What leaves your computer

Token counts, timings, model names, the stage names the workflow declared, and the grade. Not your files, not your prompts, not your shell commands. GETTING-STARTED.md sets this out in full.

Submissions go to survey.agentbenchmark.dev and nowhere else. That destination is a constant in the source rather than a setting, so a stale environment variable cannot redirect a submission onto your own disk. That is the one failure which would make a run appear successful while collecting nothing.
