For AI Developers<br>Your Agent Gets 3 Tools. 12,000+ Agent Tools. Less Context.<br>Code Mode MCP replaces 12,000+ tool definitions with 3 meta-tools. Your agent searches, reads typed API docs, and writes JavaScript to compose multi-step workflows with Filesystem, State KV, Sandbox execution, and Human Gates.<br>Try Code Mode FreeRead the Docs
How it worksFrom zero to MCP in three steps
01
Create an MCP server<br>Pick integrations, connect accounts, choose Tool Mode or Code Mode. You get an MCP endpoint; OAuth-capable clients sign in through Weavz.
02
Paste the config<br>Drop the URL into Claude Desktop, Cursor, Windsurf, or anything that speaks MCP. One JSON block.
03
Agent runs stateful work<br>Your agent can search connected apps, read typed APIs, use 12,000+ tools, persist state, and pause risky steps for approval.
Code Mode MCP3 tools instead of 200+. Context-efficient by design.<br>Tool Mode sends every action as a separate tool definition — useful but context-heavy as the catalog grows. Large tool-schema lists can cost real money and degrade agent quality as irrelevant schemas crowd out useful reasoning. Code Mode replaces all tools with 3 meta-tools that let your agent search, read, and execute on demand. The agent loads only what it needs, improving output quality and lowering token costs.
