Rein Agent Risk Scale tools (3)

write = sends, deletes, buys or posts
  • explain_gradeFree

    Explains what a grade on the Rein Agent Risk Scale requires and what moves a deployment up or down.

  • get_scaleFree

    Returns the A-D Agent Risk Rating scale, what each grade means, the methodology version and the disclaimer.

  • self_checkFree

    Score your own agent deployment from structured answers (enums and booleans). Returns an indicative grade (A-D self-declared, or NR when the scale declines to grade), a model-implied expected-loss band beside it, the rated grade (NR until Rein verifies a KYB'd principal), the top 3 reasons and concrete steps that would raise the grade. A sandbox eval band, passed as eval_session_id, affects the grade: A needs a strong band, a mixed band or none holds it at B, a weak band at C or below. Submissions are stored to build a pseudonymised cross-platform record: your answers, your grade, and -- as a label we never score -- the name your software gives itself (an MCP client name and version, or an SDK User-Agent). No IP address is stored. Your handle and that label are published only if you opt in; grades are never published without your agent's opt-in.

Rein Agent Risk Scale: MCP examples

Copy-paste examples that connect an AI agent to the Rein Agent Risk Scale self-check over MCP. The self-check gives an agent that can spend money an indicative Agent Risk Rating on an A–D scale (NR = not rated), from the controls around it: who is accountable, spend caps and where they are enforced, payee limits, a stop switch and who holds it, human escalation, monitoring, history and incidents.

MCP endpoint (streamable HTTP, no sign-in):

https://rein-scale.mangowave-ad191d9c.eastus.azurecontainerapps.io/mcp

The endpoint has three tools:

  • self_check scores a deployment from structured answers;
  • get_scale returns the A–D scale (NR = not rated) and what each grade means;
  • explain_grade says what a grade requires.

Scoring is fixed, published rules with no language model, so the same answers always give the same grade (methodology 0.3.1). Harness memory counts in your favour within your grade's band; it never moves the letter.

Self-declared and unverified; not a credit rating.

Examples

Each example is one file of under 40 lines.

The three agent examples use OpenAI by default (export OPENAIAPIKEY=...). Pass any model your framework accepts to main() to use another.

  • Tested: every example was run against the live endpoint on 7 October 2026 at the versions above.
  • Watched weekly: a check runs them against the latest framework releases, because releases rename things. mcp 2.x renamed its HTTP client, and it now yields two streams instead of three.

Use it from any MCP client

There are docs written for agents at /skill.md and /llms.txt.

What a self-check is, and is not

  • Indicative. The grade comes from your own answers. It is self-declared and unverified, so the rated grade stays NR (not rated) until the controls are verified.
  • Explained. The response lists the findings that most explain the grade and the steps that would raise it.
  • Private by default. Answers and grades are stored under a pseudonymised record. A handle is published only if you set publishoptin: true. Never send secrets or personal data.
  • Not a credit rating, not investment advice, and not an offer of credit.
