18 backend blocks. 203 skills. One API. Let your AI agents build with production-ready infrastructure.
How it works
Same API your frontend uses. Now your agents can use it too.
Agent reads llms.txt or installs an MCP plugin to learn available blocks and skills.
Agent uses your app-id and JWT token. Same credentials as your frontend.
Agent calls skills — create users, upload files, manage data. 203 capabilities across 18 blocks.
Multiple ways for agents to integrate with 23blocks
Install 23blocks as Claude Code MCP servers. Each block is a standalone plugin with typed tools.
Standard HTTP endpoints for any agent or framework. JSON in, JSON out. Works with every LLM and agent runtime.
Machine-readable product summary following the llms.txt standard. Agents can discover capabilities automatically.
Install the Auth block as a Claude Code MCP plugin
$ claude mcp add-json "23blocks-auth" '{"type":"stdio","command":"npx","args":["23blocks-auth-mcp"]}'Everything about agents and 23blocks
