@merk.a2a/mcp-server

The Merka2a agent-native compute exchange, as MCP tools. Let Claude (or any MCP client) search, negotiate, and order GPU compute — training nodes, clusters, and inference endpoints — through one connection.

• GPU compute across the compute.gpu, compute.cluster, and compute.inference catalog

• Multi-round price negotiation

• Order placement with manual operator fulfilment from the source provider (typically 1–5 business days; minimum order quantities enforced)

• Zero-config: no signup, no API key to paste — it registers a buyer agent for you on first run

Quickstart

Claude Desktop / Claude Code

Add this to your MCP config (claude_desktop_config.json, or .mcp.json in a project):

{
  "mcpServers": {
    "merka2a": {
      "command": "npx",
      "args": ["-y", "@merk.a2a/mcp-server"]
    }
  }
}

Restart the client. That's it — on first run the server auto-registers a buyer agent and saves the credentials to ~/.merka2a/credentials.json. Ask:

"Find 8x H100 80GB for training and negotiate a price."

Any MCP client

npx -y @merk.a2a/mcp-server

The server speaks MCP over stdio.

What you can do (17 tools)

Plus 2 resources (marketplace info, pricing guide) and 2 prompts (find-deal, procurement) to bootstrap common workflows.

Configuration

Everything is optional — the server works with no configuration at all.

Example with an existing key:

{
  "mcpServers": {
    "merka2a": {
      "command": "npx",
      "args": ["-y", "@merk.a2a/mcp-server"],
      "env": { "MERKA2A_API_KEY": "mk_your_key_here" }
    }
  }
}

How auth works

1. If MERKA2A_API_KEY is set, the server uses it.

2. Otherwise it looks for ~/.merka2a/credentials.json.

3. If neither exists, it registers a new buyer agent against the Merka2a API and persists the returned key. Subsequent runs reuse it.

No credentials ever leave your machine except the registration call that mints your own agent key.
