Tool names and descriptions exactly as the server reported them on Nov 10, 2026. The maker wrote them, not us; we show them as plain text.
rubrkit_search_api_docsSearch the canonical docs/api Markdown guides and OpenAPI operation summaries.
rubrkit_read_api_docRead a docs/api Markdown guide or OpenAPI source by slug, file name, or docs/api path.
rubrkit_read_openapi_contractRead the canonical docs/api/openapi.yaml contract.
rubrkit_create_artifact_bundleCreate an artifact bundle through /api/v1/artifact-bundles. Requires artifact_bundles:write for API keys.

rubrkit_read_artifact_bundleRead artifact bundle details, files, and file tree. Requires artifact_bundles:read for API keys.
rubrkit_delete_artifact_bundleArchive 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.
rubrkit_hard_delete_artifact_bundlePermanently 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 k
rubrkit_upload_artifact_filesUpload one or more text files into an artifact bundle. Requires files:write for API keys.
rubrkit_list_artifact_filesList files in an artifact bundle. Requires files:read for API keys.

rubrkit_estimate_deep_compactionEstimate the credit cost of a deep compaction of one file before starting it. Requires compactions:run for API keys.
rubrkit_apply_deep_compactionSave a succeeded deep compaction job's verified result as a new version of the file. Refused if the file changed since the job started. Requires files:write for API keys.
rubrkit_start_auditStart 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.
rubrkit_list_auditsList persisted audit history. Requires artifact_bundles:read for API keys.
rubrkit_read_auditRead a single audit run. Requires artifact_bundles:read for API keys.

rubrkit_list_golden_casesList 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.
rubrkit_add_golden_caseAdd 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.
rubrkit_retire_golden_caseRetire a golden case via DELETE /api/v1/golden-cases/{goldenCaseId}. Requires artifact_bundles:write for API keys.

rubrkit_set_drift_monitor_statusPause or resume a drift monitor via PATCH /api/v1/drift-monitors/{driftMonitorId}. Requires artifact_bundles:write for API keys.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 5 months ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
