For AI Developers

Your Agent Gets 3 Tools. 4,700+ Tools. Less Context.

Code Mode MCP replaces 4,700+ 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.

How it works

From zero to MCP in three steps

01

Create an MCP server

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

Drop the URL into Claude Desktop, Cursor, Windsurf, or anything that speaks MCP. One JSON block.

03

Agent runs stateful work

Your agent can search 500+ integrations, read typed APIs, use 4,700+ tools, persist state, and pause risky steps for approval.

Code Mode MCP

3 tools instead of 200+. Context-efficient by design.

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.

API details load on demand

weavz_search

Search available integrations and tools by keyword

weavz_search({ query: "slack" })
weavz_read_api

Read full API docs for one or more aliases on demand

weavz_read_api({ aliases: ["office_slack"] })
weavz_execute

Execute multi-step integration workflows in code

weavz_execute({ code: `
  const channels = await weavz.office_slack.list_channels({});
  await weavz.office_slack.send_channel_message({
    channel: channels[0].id,
    text: "Hello from AI!"
  });
` })
Stateful Runtime

The primitives agents need after the API call

Agents are better when they can carry context forward, produce artifacts, transform data, and ask for approval before the expensive or irreversible step.

Filesystem

Store generated files, research outputs, logs, and artifacts across agent runs with end-user, workspace, or external scoping.

State KV

Keep cursors, checkpoints, lightweight memory, and workflow state close to the tools that need it.

Sandbox

Let agents run deterministic JavaScript, Python, and Shell steps for transforms, parsing, and custom execution.

Human Gates

Pause sensitive executions until a reviewer approves, rejects, or edits the request, then resume with the audit trail intact.

What your agent can actually reach

Slack, GitHub, Salesforce, Google Sheets, HubSpot, and hundreds more. Each integration ships with pre-built tools and triggers - no API wrappers to write.

Quick Start

Paste a JSON block. Done.

Add this to claude_desktop_config.json and your agent can call Slack, Google Sheets, GitHub, and everything else on your MCP server.

claude_desktop_config.json
{
  "mcpServers": {
    "weavz": {
      "url": "https://api.weavz.io/mcp/srv_abc123"
    }
  }
}
