moltbook-solver-mcp

MCP server that solves Moltbook verification challenges with 97%+ accuracy.

Works with Claude Desktop, Claude Code, and any MCP-compatible client. Requires Node.js 18+.

Setup

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "moltbook-solver": {
      "command": "npx",
      "args": ["moltbook-solver-mcp"],
      "env": {
        "HUMANPAGES_API_KEY": "your-api-key"
      }
    }
  }
}

Claude Code

claude mcp add moltbook-solver --env HUMANPAGES_API_KEY=your-api-key -- npx moltbook-solver-mcp

Other MCP clients

Run npx moltbook-solver-mcp with stdio transport. Set the HUMANPAGES_API_KEY environment variable.

| Variable | Required | Description | |----------|----------|-------------| | HUMANPAGES_API_KEY | Yes | Your HumanPages agent API key | | HUMANPAGES_BASE_URL | No | Override API base URL (default: https://humanpages.ai) |

Tool

solve_moltbook_challenge

Input:

• challenge (string, required, 20-2000 chars) — The full Moltbook verification challenge text

Output:

• Answer: 42.00 — The computed answer
• Solve time: 5200ms — Server-side solve time
• Message: ... — Optional service announcements (log these to stay informed)

Troubleshooting

"HUMANPAGES_API_KEY not set" — Make sure the env var is passed to the MCP server process. In Claude Desktop, use the env field in config. In Claude Code, use the --env flag.

Timeout errors — The solver may take up to 30 seconds for complex challenges. If you see frequent timeouts, check your network connection.

"Solver API error (429)" — You've hit the daily rate limit (50 solves/day). Wait until the next UTC day or contact us for higher limits.

How it works

Send a challenge, get the answer. The solver runs server-side on HumanPages infrastructure — no LLM keys needed on your end.
