Summary

MCP server for AgentMark. Exposes the full AgentMark API to AI editors: list traces and spans, manage datasets, write scores, run experiments, manage apps, deployments, environments, and annotation queues.

Connect from your MCP client

One-click install

Add this server to your editor with a single click. Fill in any required credentials afterward.

Claude Code

Run this once and Claude Code registers the server for you:

claude mcp add agentmark -- npx -y @agentmark-ai/mcp-server

Claude Desktop

Add this to claude_desktop_config.json under Settings → Developer → Edit Config:

{
  "mcpServers": {
    "agentmark": {
      "command": "npx",
      "args": [
        "-y",
        "@agentmark-ai/mcp-server"
      ],
      "env": {
        "AGENTMARK_API_KEY": "<AGENTMARK_API_KEY>",
        "AGENTMARK_API_URL": "<AGENTMARK_API_URL>"
      }
    }
  }
}

Cursor

Add this to .cursor/mcp.json in your project (or ~/.cursor/mcp.json for all projects):

{
  "mcpServers": {
    "agentmark": {
      "command": "npx",
      "args": [
        "-y",
        "@agentmark-ai/mcp-server"
      ],
      "env": {
        "AGENTMARK_API_KEY": "<AGENTMARK_API_KEY>",
        "AGENTMARK_API_URL": "<AGENTMARK_API_URL>"
      }
    }
  }
}

Cline and other MCP clients

Most MCP clients accept the standard mcpServers JSON block:

{
  "mcpServers": {
    "agentmark": {
      "command": "npx",
      "args": [
        "-y",
        "@agentmark-ai/mcp-server"
      ],
      "env": {
        "AGENTMARK_API_KEY": "<AGENTMARK_API_KEY>",
        "AGENTMARK_API_URL": "<AGENTMARK_API_URL>"
      }
    }
  }
}

Codex CLI

Register the server with OpenAI's Codex CLI — run this once, or add the equivalent block to ~/.codex/config.toml:

codex mcp add agentmark --env AGENTMARK_API_KEY=<AGENTMARK_API_KEY> --env AGENTMARK_API_URL=<AGENTMARK_API_URL> -- npx -y @agentmark-ai/mcp-server

# or add to ~/.codex/config.toml:
[mcp_servers.agentmark]
command = "npx"
args = ["-y", "@agentmark-ai/mcp-server"]
[mcp_servers.agentmark.env]
AGENTMARK_API_KEY = "<AGENTMARK_API_KEY>"
AGENTMARK_API_URL = "<AGENTMARK_API_URL>"

OpenClaw

OpenClaw reads MCP servers from the mcp.servers section of ~/.openclaw/openclaw.json (managed via `openclaw mcp add` or the mcporter skill):

{
  "mcp": {
    "servers": {
      "agentmark": {
        "command": "npx",
        "args": [
          "-y",
          "@agentmark-ai/mcp-server"
        ],
        "env": {
          "AGENTMARK_API_KEY": "<AGENTMARK_API_KEY>",
          "AGENTMARK_API_URL": "<AGENTMARK_API_URL>"
        }
      }
    }
  }
}
