Machine-readable spec

OpenAPI spec retrieved

Published by the vendor themselves — not community forks.

• fiber-ai-plugin

  MCP servers, skills, hooks, and slash commands packaged into a single installable unit for coding agents; 2 stars at check time.

• open-fiber

  Open-source sales/recruiting UI built on Fiber's APIs, offered as a starting point for a custom UI or as working examples.

It is built explicitly for agent consumption: per-operation markdown pages at /ai-docs/<operationId>.md, an llms.txt routing file, TypeScript/Python SDKs, and three distinct MCP servers offering different tradeoffs between tool-count and ease of auth.

In-house GTM/sales teams building outbound pipelines, recruiting and staffing organizations sourcing at scale, AI SDR/recruiting automation platforms, RevOps teams running repeatable enrichment workflows, and developers wiring enrichment into signup flows or internal tools.

Fiber AI does not publish pricing anywhere on its own site - no /pricing page exists and no plan names or figures appear in the docs, so budget-conscious buyers cannot self-serve a cost estimate before engaging. Its docs and integration surface (three separate MCP servers, per-operation markdown pages, an llms.txt routing file) are built for agent/developer consumption; teams wanting a no-code UI-first enrichment tool with a simple dashboard are not the audience this product is built for.

No curated rival set covers this tool yet, so these are simply other tools in the same architectural layer and product form. Treat it as a starting point, not a shortlist.
