# List a project's skills

`GET /projects/{projectId}/skills`

The Cloud Skills visible to the caller in this project: the project-shared ones plus the caller's own drafts. Each row reports `pinnability`, which is what decides whether its id is usable in an environment's `skillSelection`.

## Path parameters

- `projectId` string, required

## Response `200`

The project's skills.

- SkillPage
  - `items` Skill[], required
    - `id` string, required
    - `projectId` string, required
    - `name` string, required — Load-bearing identity: the on-box directory name and the `loadSkill` argument. Immutable — renames are rejected.
    - `description` string, required
    - `sharing` 'user' | 'project', required — `project` skills are shared with the organization and are the only ones an environment may pin. `user` skills are the caller's own drafts.
    - `isOwner` boolean, required
    - `aggregateHash` string, required — Drift key over the body and any supporting files. A skill body is mutable and an edit overwrites it in place, so this is the only handle on WHICH content a given pin resolved to.
    - `provenance` string — How the row came to exist (`authored`, `computer-adopted`, …). Absent on older records; treat an unknown value as `authored`.
    - `pinnability` object — Whether this skill may be pinned into an environment. ABSENT means unknown (an older backend), which is not the same as eligible.
      - `ok` boolean, required
      - `reason` string — Why not, when `ok` is false — e.g. the skill is personal, carries supporting files, or carries extra frontmatter.
    - `createdAt` number, required
    - `updatedAt` number, required

## Other responses

- `401` — Missing, invalid, revoked, or orphaned key (`UNAUTHORIZED`) — or the **target MCP server** needs an OAuth grant (`OAUTH_REQUIRED`), which is a property of the server, not your key.
- `403` — Key is valid but not allowed to do this.
- `404` — Unknown project, server, or resource.
- `429` — Per-key rate limit exceeded (60 requests/minute sustained, bursts up to 10). Honor `Retry-After` and back off with jitter.
- `500` — Something failed on MCPJam's side.
- `502` — Could not connect to the target MCP server.
