Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server DecimalAI Skills Registry for Claude on this computer, in this order: 1) Check uv with uv --version. If it is missing, tell me to install it from https://docs.astral.sh/uv/getting-started/installation/; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "registry": { "command": "uvx", "args": [ "decimalai-mcp" ] } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) No key is needed. 5) Do what we agreed, then check that the DecimalAI Skills Registry tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

Common questions

Is DecimalAI Skills Registry safe?

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.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 4 days ago, and the latest version (0.1.5) reached the registry 4 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

decimalai-mcp

*Part of DecimalAI. Most users want the Python SDK → decimal-labs/decimalai-python.*

MCP server for the DecimalAI skills registry — the registry that ranks agent skills by measured effectiveness (verified A/B benchmarks, live pass rates, AI rater scores), not download counts.

Gives any MCP client (Claude Desktop, Claude Code, Cursor, …) three read-only tools:

Tool	What it does
`search_skills(query, category?, sort?, limit?)`	Hybrid keyword/semantic search over the public registry
`get_skill(slug)`	Full record: trust & safety-scan status, verified benchmark lift, SkillScore, ratings, SKILL.md body, and how to install it (`decimalai skills add` , the folder it lands in, and the Claude Code `--plugin-dir` line)
`get_leaderboard(sort?, category?, window_days?, limit?)`	Ranked leaderboard: `skill_score`, `biggest_improvement`, `efficiency`, `top_rated`

No API key required — all three tools read public registry endpoints. If you set DECIMAL_API_KEY (from app.decimal.ai/settings), the same tools additionally show which skills your org has already installed (installed_as).

Install

pip install decimalai-mcp

or, no install needed at config time:

uvx decimalai-mcp

Requires Python 3.10+.

Claude Code

claude mcp add decimalai -- uvx decimalai-mcp

with an API key:

claude mcp add decimalai -e DECIMAL_API_KEY=dai_sk_... -- uvx decimalai-mcp

Claude Desktop

Add to claude_desktop_config.json (Settings → Developer → Edit Config):

"mcpServers": { "decimalai": { "command": "uvx", "args": ["decimalai-mcp"], "env": { "DECIMAL_API_KEY": "dai_sk_optional" } } } }

Omit the env block entirely for anonymous read-only access.

Configuration

Env var	Default	Purpose
`DECIMAL_API_KEY`	(unset)	Optional. Unlocks per-org enrichment (e.g. `installed_as`) on the same public endpoints.
`DECIMAL_API_URL`	`https://api.decimal.ai`	Point at a self-hosted / local backend.

Why no `check_manifest_impact` tool?

The manifest-impact endpoint (POST /api/v1/regression-check) is authenticated on the platform — it analyzes your org's production traces against a candidate manifest, so there is no public variant to expose. This server is deliberately a read-only, key-optional public-registry surface. If demand shows up, an authed check_manifest_impact (requiring DECIMAL_API_KEY) is a natural v0.2 addition; the regression-check GitHub Action covers the CI use-case today.

Endpoints used (all public)

GET /api/v1/registry/skills — browse/search
GET /api/v1/registry/skills/{slug} — detail
GET /api/v1/registry/leaderboard — ranked leaderboard (category filtering falls back to the browse endpoint's documented view=ranks mode, because the leaderboard endpoint is uncategorized)

Development

pip install -e ".[dev]"

pytest # all HTTP mocked; no network python -m decimalai_mcp.server # run over stdio

Run pytest yourself before opening a PR. CI also asserts that the pinned mcp<2 still provides FastMCP, which the mocked tests do not cover — run that one too:

python -c "from mcp.server.fastmcp import FastMCP; import decimalai_mcp.server"

Releases are cut from a published GitHub Release — see RELEASING.md for the gates a change has to pass and the version strings that must move together.
