ArgumentsA call is made on an account: it counts against an allowance and the publisher sees it, which is why this one asks who you are first.
What it does
MCP-native AI evaluation: rubric audits, eval suites, and proof reports for AI/LLM output.
Quickstart
# 1 — install (mcprush login holds a key from your dashboard)
npx mcprush@latest add rubrkit-mcp
# 2 — ask your agent something
> MCP-native AI evaluation: rubric audits, eval suites, and proof reports for AI/LLM output.
Rubrkit is free: there is no plan to choose, no cap to set and nothing that can bill you.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine — this server runs on the publisher’s own infrastructure behind our gateway, and what you install is the connection to it.
This is a public server: you run it yourself and this marketplace is not in the path. Claude Code registers it in one command.
claude mcp add --transport http rubrkit-mcp https://www.rubrkit.com/api/v1/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing at the gateway. The server itself runs on the publisher’s own infrastructure, so nothing from this listing executes on your machine.
41 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Takes no parameters.
Read a docs/api Markdown guide or OpenAPI source by slug, file name, or docs/api path.
Takes no parameters.
Read the canonical docs/api/openapi.yaml contract.
Takes no parameters.
Create an artifact bundle through /api/v1/artifact-bundles. Requires artifact_bundles:write for API keys.
Takes no parameters.

Takes no parameters.
Read artifact bundle details, files, and file tree. Requires artifact_bundles:read for API keys.

Archive an artifact bundle (soft delete) through DELETE /api/v1/artifact-bundles/{artifactBundleId}. The bundle moves to the archived state and can be restored or permanently deleted later. Requires artifact_bundles:write for API keys.
Takes no parameters.
Permanently delete an archived artifact bundle and all of its files, versions, and run history through DELETE /api/v1/artifact-bundles/{artifactBundleId}/permanent. This is irreversible and only works on bundles that are already archived. Requires artifact_bundles:write for API keys.
Takes no parameters.
Upload one or more text files into an artifact bundle. Requires files:write for API keys.
Takes no parameters.

Takes no parameters.
Read the latest file metadata and content. Requires files:read for API keys.
Takes no parameters.
Write a new editable version for a file. Requires files:write for API keys.
Takes no parameters.
Start an async audit job. Audit results are cached per account by a content hash of their inputs; pass force: true to bypass the cache and run a fresh audit (the same as the CLI's --no-cache flag). Requires audits:run for API keys.
Takes no parameters.
List persisted audit history. Requires artifact_bundles:read for API keys.
Takes no parameters.
Read a single audit run. Requires artifact_bundles:read for API keys.
Takes no parameters.
Apply a completed audit's AI rewrite to the bundle files (a new version per changed file). Requires audits:run for API keys.
Takes no parameters.

Takes no parameters.
List conversion history. Requires artifact_bundles:read for API keys.
Takes no parameters.
Read one conversion report. Requires artifact_bundles:read for API keys.
Takes no parameters.
Read async job progress. Requires jobs:read for API keys.
Takes no parameters.
Read append-only job progress events. Requires jobs:read for API keys.

Takes no parameters.
Restore files from a prior artifact-bundle version by creating new file versions. Requires artifact_bundles:write and files:write for API keys.
Takes no parameters.
List immutable versions for a file. Requires files:read for API keys.
Takes no parameters.
Restore a prior file version by creating a new version. Requires files:write for API keys.
Takes no parameters.
Start an async eval run. Requires evals:run for API keys. Set mode: "advanced" with baselineVersionId and candidateVersionId to run a statistically-backed A/B (repeats defaults to 3, max 5).
Takes no parameters.
List eval history. Requires artifact_bundles:read for API keys.
Takes no parameters.
Read one eval run, including the `stats` statistical verdict on advanced-mode runs (empty for standard runs). Requires artifact_bundles:read for API keys.
Takes no parameters.
Start an async proof report job with export storage enabled by default. Requires evals:run for API keys.
Takes no parameters.
Read one proof report. Requires artifact_bundles:read for API keys.
Takes no parameters.
List the golden cases for an artifact bundle via /api/v1/artifact-bundles/{artifactBundleId}/golden-cases. Requires artifact_bundles:read (or artifacts:pull) for API keys.
Takes no parameters.
Add a golden case (a real edge-case input with a confirmed-correct output) to an artifact bundle via POST /api/v1/artifact-bundles/{artifactBundleId}/golden-cases. Requires artifact_bundles:write for API keys.
Takes no parameters.
Retire a golden case via DELETE /api/v1/golden-cases/{goldenCaseId}. Requires artifact_bundles:write for API keys.

Takes no parameters.
List the recorded observations for a drift monitor via /api/v1/drift-monitors/{driftMonitorId}/observations. Requires artifact_bundles:read (or artifacts:pull) for API keys.
Takes no parameters.
Queue a drift check immediately instead of waiting for the monitor's schedule, via POST /api/v1/drift-monitors/{driftMonitorId}/check. The first check on a new monitor calibrates its baseline. Costs one audit per repeat. Requires artifact_bundles:write for API keys.
Takes no parameters.
Pause or resume a drift monitor via PATCH /api/v1/drift-monitors/{driftMonitorId}. Requires artifact_bundles:write for API keys.
Takes no parameters.

Takes no parameters.
Compare recent production inputs against a prior reference window (population stability index) for an artifact bundle via GET /api/v1/artifact-bundles/{artifactBundleId}/drift/input. Requires artifact_bundles:read (or artifacts:pull) for API keys.
Takes no parameters.
Correlate rubric scores against recorded outcome metrics for an artifact bundle to check whether the rubric is still predictive via GET /api/v1/artifact-bundles/{artifactBundleId}/drift/validity. Requires artifact_bundles:read (or artifacts:pull) for API keys.
Takes no parameters.

What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable. Rubrkit costs nothing to install and nothing to call, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is a hosted endpoint: the publisher runs it and we connect to it. The scanner reads packages and source, and neither exists to read here, so there is no grade — not a withheld one, an unmeasured one. What can be checked instead is on Installation: what it asks to reach and what it writes.
Release history
Pinned to 0.1.0 — the install command below asks for that release. A pin is part of an install, so it is kept for this visit and written down when you install.
No release note was published with this version.
Only accounts with at least 50 real tool calls against this server in the last 90 days can post. Ratings are weighted by how much the reviewer actually uses it, and publishers can reply once per review.
Writing one takes an account with at least 50 real tool calls against Rubrkit in the last 90 days. That is the whole gate — there is no other way to post, which is why the counts beside each review are worth reading.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes an account with 50 real tool calls against it.
