Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it. View diagnostics → Pass
- 0 of 29 dependencies flagged as unhealthy. View diagnostics → Pass
Provenance & Transparency48
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 36 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability69
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 463 tokens (~154/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management83
- Stability observed for 25 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the DecimalAI Skills Registry MCP server?
DecimalAI Skills Registry runs locally as a PyPI package, launched with uvx decimalai-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_leaderboard ~114
Ranked skills leaderboard. Args: sort: skill_score | biggest_improvement | efficiency | top_rated. category: Optional category filter (uses the registry's ranked browse view — the dedicated leaderboard endpoint is uncategorized). window_days: Ranking window in days (1-3650; ignored for skill_score). limit: Max entries (1-50).

No examples provided.
get_skill ~166
Get one skill's full record: trust/safety-scan status, verified benchmark evidence (lift vs no-skill baseline), SkillScore, ratings, and the SKILL.md body. Args: slug: The skill's `url_slug` from search results — NOT its `name`. A registry name may be namespaced (`owner/skill`), and a slash cannot survive a single URL path segment, so a namespaced name 404s here. `url_slug` is the slash-free identifier minted for exactly this (`owner/skill` -> `owner-skill`); for a plain un-namespaced name the two are identical. The skill's UUID `id` also works.

search_skills ~117
Search the public DecimalAI skills registry. Args: query: Keyword or natural-language query (hybrid keyword/semantic search). category: Optional category filter (e.g. "retrieval", "code-review"). sort: recommended (SkillScore v2, default) | lift | popular | top_rated | efficiency | rating | recent. limit: Max results (1-50).
