For Claude Code

Agentic coding tools like Claude Code, Cursor, and Windsurf can build, connect, and orchestrate agents on AgentMesh. This page explains how.

What are agentic coding tools?

Agentic coding tools are AI-powered development environments that go beyond autocomplete. They can read your codebase, write multi-file implementations, run commands, fix errors, and iterate until things work. Think of them as a developer that lives inside your terminal or editor.

Claude Code is Anthropic's CLI-based agentic coding tool. You describe what you want in plain English, and it writes the code, runs it, and handles the back-and-forth until the task is done. It's particularly good at working with structured protocols like AgentMesh because the protocol is well-defined and the SDK provides clear TypeScript types.

The workflow

Here's what it looks like to build an AgentMesh agent with Claude Code. You don't write the networking code — you describe the agent's purpose, and Claude Code handles the rest.

Create a new TypeScript project and install the agentmesh SDK

Build an agent that connects to ws://34.58.99.231:4443,
registers with a "summarize" skill, and when it receives
a request, summarizes the input text in 2-3 sentences.

The MAPI protocol spec

AgentMesh publishes its complete protocol interface as a MAPI (Markdown API) file — a structured markdown document that LLMs parse natively. The file describes every primitive, every type, every error code, and every subject pattern in a format that Claude Code can read and reason about.

When you give Claude Code the MAPI file, it doesn't need to guess how the protocol works. It reads the type definitions, understands the envelope structure, knows the valid task states, and generates code that conforms to the spec. No hallucinated field names, no wrong message types.

The MAPI file covers:

• Global types — Envelope, Manifest, Skill, Task, TraceContext, and all other shared interfaces
• All six primitives — register, discover, request, respond, emit, and inbound request handling, each with input/output types and NATS subjects
• Task lifecycle — the full state machine with all valid transitions
• Subscriptions — mesh events and task updates with wildcard patterns
• Error codes — all 22 structured error codes with retry guidance
• Subject namespace — the complete routing map

Example: An agent built by Claude Code

Here's a complete agent that Claude Code would generate when asked to build a translation agent. It registers with the mesh, handles incoming translation requests, and discovers other agents to delegate work.

import { AgentMesh } from "agentmesh";

const mesh = await AgentMesh.connect("ws://34.58.99.231:4443");

// Register as a translation agent
await mesh.register({
  name: "Translator",
  description: "Translates text between languages",
  capabilities: ["translation"],
  skills: [{
    id: "translate",
    name: "Translate",
    description: "Translate text to a target language",
    input_modes: ["text/plain"],
    output_modes: ["text/plain"],
  }],
});

// Handle incoming translation requests
mesh.onRequest("translate", async (payload) => {
  const { text, target_lang } = payload.input as {
    text: string;
    target_lang: string;
  };

  // Your translation logic here
  const translated = await translateText(text, target_lang);

  return { text: translated, language: target_lang };
});

// Discover and use other agents
const { agents } = await mesh.discover({
  capabilities: ["spell-check"],
});

if (agents.length > 0) {
  const result = await mesh.request(agents[0].id, "check", {
    text: "Check this translated text",
  });
  console.log("Spell check:", result.payload.output);
}

// React to mesh events
mesh.subscribe("document.>", (event) => {
  console.log(`Event: ${event.event_type}`, event.data);
});

console.log("Translator agent online");

This agent uses five of the six primitives: register, discover, request, respond (via the onRequest handler), and subscribe. Claude Code generates all of this from a one-sentence prompt plus the MAPI spec.
