Landseed OS · Agent substrate

The substrate for everything Landseed.

Three named agents — Verifier, Methodologist, Captain — running on a Forgejo-scoped MCP gateway. Brand canon, methodology, calculator, registry, and motion grammar in one place. Attach from any Claude surface. Output is production grade by construction.

The fleet

Voice. Theory. Evidence.

Each agent maps to a pillar of the assay-office thesis. They share a single substrate (brand canon, methodology spec, calculator, registry) so the engineering compounds.

Connect

Attach in under five minutes.

The gateway is one URL: landseed-os.aroessner1.workers.dev/<SECRET>/mcp. Get the secret from ~/.claude/CREDENTIALS-MAP.md (operator Mac keychain entry landseed-os-gateway-secret). Pick your surface below.

How to attach

Add to ~/.claude.json under projects['/your/project'].mcpServers:

"landseed-os": {
  "type": "http",
  "url": "https://landseed-os.aroessner1.workers.dev/<GATEWAY_SECRET>/mcp"
}

Restart Claude Code. /mcp will list landseed-os.

Settings → Custom Connectors → Add

https://landseed-os.aroessner1.workers.dev/<GATEWAY_SECRET>/mcp

Name: Landseed OS. Transport: HTTP. Enable per-conversation.

Cowork inherits Claude.ai's connector configuration. Add the connector once at Claude.ai (see tab above), Cowork picks it up automatically.

Use the official @modelcontextprotocol/sdk HTTP transport:

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js";

const url = new URL("https://landseed-os.aroessner1.workers.dev/<SECRET>/mcp");
const transport = new StreamableHTTPClientTransport(url);
const client = new Client({ name: "my-app", version: "1.0" }, { capabilities: {} });
await client.connect(transport);

Receipts

The public registry, live.

Every Earth Credit assessment recorded in the public ledger. Pulled live from calc-api.landseed.earth. This is what the Verifier walks when asked to show provenance.
