OpenClaw

OpenClaw is a personal AI agent that can browse and use tools. It supports MCP servers and skills.

#Connect the MCP server

Add the server in openclaw.json:

{
  mcp: {
    servers: {
      solvecha: {
        url: "https://api.solvecha.com/mcp",
        transport: "streamable-http",
        headers: { Authorization: "Bearer ${SOLVECHA_API_KEY}" }
      }
    }
  }
}

Set transport explicitly. OpenClaw assumes sse otherwise. Keep the key in an environment variable. A literal key in headers makes openclaw mcp doctor warn.

You can add the server from the command line as well. The flags are --url, --transport and --header:

openclaw mcp add solvecha --url https://api.solvecha.com/mcp --transport streamable-http --header "Authorization: Bearer YOUR_API_KEY"
openclaw mcp doctor --probe

Run openclaw mcp add --help to see the header syntax of your version. The tools are listed on the MCP server page.

#Let the browser solve it with the extension

If OpenClaw drives a Chrome that has the Solvecha extension, the extension solves reCAPTCHA image challenges without any tool call. OpenClaw can attach to a browser through a profile with a cdpUrl:

{
  browser: {
    profiles: {
      solvecha: { cdpUrl: "http://127.0.0.1:9222" }
    }
  }
}

Start Chrome with a separate profile folder, a debugging port and the unzipped extension (see Hermes Agent for the command), save your key in the extension options, and select this profile.

#Add the skill

OpenClaw loads a skill from a folder with a SKILL.md. Put the Solvecha agent skill in ~/.openclaw/skills/solvecha/SKILL.md (all agents) or in skills/solvecha/SKILL.md of your workspace.
