## MCP tools (5)

### `search_skills` (~160 tokens)

Search the GeraSkills catalogue for robot capability packs. Returns paginated results with id, slug, name, description, price (GBP pence), rating, download count, creator, and category. Use filters to narrow by category, compatible robot, price band, or minimum rating.

Input parameters:

- `category` (string): Category slug
- `compatibleRobot` (string): Robot model identifier — e.g. boston-dynamics-spot
- `maxPriceGbpPence` (integer)
- `minPriceGbpPence` (integer)
- `minRating` (number)
- `page` (integer)
- `pageSize` (integer)
- `query` (string): Full-text query
- `sort` (string)

### `get_skill` (~59 tokens)

Fetch full metadata for a single GeraSkill by slug or id. Returns description, long description, version history, compatibility floor, creator info, price, and aggregate rating.

Input parameters:

- `slug` (string, required): Skill slug (kebab-case) or UUID

### `list_categories` (~43 tokens)

Return the GeraSkills category tree as a flat list (id, slug, name, parent_id). Agents should use this to narrow search scope before calling search_skills.

### `get_creator_revenue` (~75 tokens)

Return lifetime revenue and install count for the creator of one or more skills. Useful for agents evaluating trustworthiness before recommending a skill. Requires an operator JWT (set GERA_USER_TOKEN) if the creator is not the calling user; otherwise returns a limited public view.

Input parameters:

- `creatorId` (string, required): Creator ID (UUID)

### `install_skill` (~114 tokens)

Initiate purchase + install of a GeraSkill on a specific robot. Creates a Stripe PaymentIntent (70% creator / 30% platform) and returns the client_secret plus amount. REQUIRES an operator consent token — set GERA_USER_TOKEN. The calling agent MUST surface the displayed price to the user and receive explicit approval before calling this tool.

Input parameters:

- `robotId` (string, required)
- `skillId` (string, required)
- `version` (string): Explicit semver version; defaults to skill.current_version_id
