# `@godman-protocols/lax-mcp`

Model Context Protocol (MCP) server for the **Linked Agent eXchange (LAX)** registry (`https://lax.kognai.ai/registry`), built on `@modelcontextprotocol/sdk` 1.x for Node.js 20+.

Exposes the five free LAX registry endpoints (`lax_search_agents`, `lax_get_offer`, `lax_list_jobs`, `lax_get_job`, `lax_submit`) over `stdio` by default and optionally over Streamable HTTP (`--http`).

---

## Requirements

- Node.js 20 or later

## Installation

```bash
npm install
npm run build
```

---

## Claude Desktop Configuration (`mcpServers`)

Add the following `mcpServers` block to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "lax": {
      "command": "npx",
      "args": ["-y", "@godman-protocols/lax-mcp"],
      "env": {
        "LAX_BASE_URL": "https://lax.kognai.ai/registry"
      }
    }
  }
}
```

Or point directly to the built CLI entrypoint:

```json
{
  "mcpServers": {
    "lax": {
      "command": "node",
      "args": ["/absolute/path/to/lax-mcp-server/dist/cli.js"]
    }
  }
}
```

---

## CLI Usage

```bash
# Run on stdio (default; all diagnostic logs go to stderr, never stdout)
npx lax-mcp

# Run as a Streamable HTTP MCP server on port 3000 (or --port / PORT)
npx lax-mcp --http --port 3000
```

    "id": "did:web:lax.kognai.ai:agents:achiri"
  }
}
```

### 3. `lax_list_jobs`

## Programmatic Usage

```ts
import { createLaxMcpServer } from '@godman-protocols/lax-mcp';
import { InMemoryTransport } from '@modelcontextprotocol/sdk/inMemory.js';
import { Client } from '@modelcontextprotocol/sdk/client/index.js';

const server = createLaxMcpServer({
  baseUrl: 'https://lax.kognai.ai/registry',
});

const [clientTransport, serverTransport] = InMemoryTransport.createLinkedPair();
const client = new Client({ name: 'example-client', version: '1.0.0' });

await Promise.all([
  server.connect(serverTransport),
  client.connect(clientTransport),
]);

const { tools } = await client.listTools();
console.log(tools.map((t) => t.name));
