federated ecosystem · breadth tier

30,000+ tools through one MCP.

We federate from the open ecosystem — Smithery, Composio, Pipedream, Mastra, awesome-lists. Quality varies. These are not our 0 Top-Verified flagships — they are the breadth tier, gated by Verify-First.

ADR-005 · Verify-First gate

How federated tools earn the right to be callable.

We don't blindly federate. Every upstream tool passes through a Verify-First gate before it can be invoked from your Pak. The bespoke flagships live on the verified side. The federated tier lives on the breadth side — clearly labeled, clearly fenced.

gate 1

Source attestation

Upstream registry signs the manifest. We record the canonical URL, license, and last-known-good hash before the tool enters our index.

gate 2

Static & schema check

Schema valid, no obvious credential leaks, no destructive defaults. Tools that fail here never surface.

gate 3

Sandbox handshake

A canary call validates the upstream still responds. Idempotency and timeout behavior recorded for the receipt.

gate 4

Source-labeled forward

Calls flow through skill.ski with the upstream label intact. Your agent sees provenance on every result; no quiet rewrites.

discover → callable

Four steps from public registry to your Pak

STEP 01

Discover

We index public registries — Smithery, Composio, Pipedream, Mastra, and community awesome-lists — on a recurring crawl.

STEP 02

Discovered tools are normalized into the skill.ski catalog schema and tagged with their upstream source and sector.

STEP 03

User connects

Add skill.ski's MCP endpoint to your AI client. All federated tools surface alongside our verified flagships — source-labeled.

STEP 04

Tool callable

Your agent calls the tool through skill.ski's MCP. We forward to the upstream endpoint with provenance preserved.
