Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  List Arc components and blocks with name, description, tier, and links. Filter by category (Actions, Inputs, Disclosure, Feedback, Data, Text, Special, Blocks), tag, tier (free or pro), or kind (component or block).

• get_skill unknown 31m ago

  Get one Arc skill file as markdown: rules for building with Arc. Free skills: SKILL (entry point: workflow, principles, never-do list, and quick decisions); INSTRUCTIONS (short always-on rules for agents.md, claude.md, or cursor rules); checklist (the review loop to run before finishing, with grep sweeps); components (choosing the right component or block by job, with ids); composition (page containers, dashboards, marketing sections, states, react correctness); copy (sentence case, no eyebrows or em dashes, verbs on buttons, honest claims); design (color, type, surfaces, concentric radii, spacing, and icons); motion (motion tokens, spring choice, patterns with code, reduced motion); accessibility (focus without rings, semantics, keyboard, and announcements); responsive (widths to check, overflow, tables, and touch targets); example-settings (a worked account settings page); example-pricing (a worked pricing section with plans, comparison, and faq); example-dashboard (a worked analytics overview with kpis, chart, and table). Pro skills (arc-pro, full-page-generation, page-composition, design-system-generation, refactor-to-arc, motion-recommendations, responsive-optimization, accessibility-audit) are returned in full when the connection carries an Arc Pro token (otherwise signed-in Pro members download them at /api/skills and this tool returns where).

• get_component unknown 31m ago

  Get full documentation for one Arc component or block: when to use it, when not to (with the better alternative), usage and extra examples, props, keyboard, accessibility, motion, responsive behavior, performance, keywords, related items, and the install command. structuredContent.api carries the same fields as JSON. With an Arc Pro token (Authorization header), Pro items also include their full source files in structuredContent.files.

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
