Five Blocks offers three ways for AI agents and developers to work with us: a public content API, a public docs MCP server, and two client MCP servers for AIQ and IMPACT data.
Content API (public, no key)
Read-only access to the published content on fiveblocks.com: services, research, Knowledge Center answers and blog posts.
- Search: www.fiveblocks.com/api/v1/search with the parameter q (your search words) and optional limit (1 to 20)
- Read a page as markdown: www.fiveblocks.com/api/v1/page with the parameter slug (the page path)
- OpenAPI specification: www.fiveblocks.com/openapi.json
Errors come back as JSON with a code, a message and a hint. Any page on the site is also available as markdown by adding .md to its address, for example www.fiveblocks.com/about.md.
Docs MCP server (public, no sign-in)
Server URL: www.fiveblocks.com/docs-mcp (Streamable HTTP). Tools: search Five Blocks content, read a page, and get an overview of the firm. All tools are read-only.
Client MCP servers (AIQ and IMPACT)
Five Blocks clients can connect AI assistants such as Claude to their AIQ and IMPACT data. Both servers require sign-in with an existing account. Details: Five Blocks MCP servers.
- AIQ: aiq-mcp.fiveblocks.com/mcp
- IMPACT: impact-mcp.fiveblocks.com/mcp
Agent discovery files, including the AI catalog and agent skills index, are listed in the site index at www.fiveblocks.com/index.md.

Limits, versions and pricing
The content API allows 60 requests per minute per client and reports this in RateLimit headers; a 429 response includes Retry-After. The version is in the address (/api/v1). Before a version is retired, its responses carry Deprecation and Sunset headers for at least 90 days, and the change is announced on this page. Starting rates for Five Blocks programs are at fiveblocks.com/pricing.md.
