xiaobai-print

This repository now centers on the wrapper-skill flow:

1. Run a local HTTP bridge

2. Read the bridge tool list

3. Generate one or more OpenClaw skill directories

4. Let each skill call the bridge through a local invoke.js

The repository still includes the stdio MCP server for Claude Desktop / Cursor, but the recommended OpenClaw path is:

OpenClaw skill -> scripts/invoke.js -> local HTTP bridge -> remote MCP

Build

npm install
npm run build

Related MCP server: claudecode-mcp

Executables

• xiaobai-print-mcp: stdio MCP server

• xiaobai-print-bridge: local HTTP bridge for generated skills

• generate-openclaw-skill: skill generator that reads the bridge tool list

Run The Local Bridge

Start the local HTTP bridge on 127.0.0.1:8787:

MY_MCP_UPSTREAM_URL="https://mcp.gongfudou.com/mcp/openclaw/sse" \
MY_MCP_TOKEN="your-token" \
xiaobai-print-bridge

Or use the compiled file directly:

node dist/bridge/http.js --host 127.0.0.1 --port 8787

Bridge endpoints:

• GET /health

• GET /mcp/tools

• POST /mcp/tools/{toolName}

The bridge accepts Authorization: Bearer <token> per request. If the request omits Authorization, it falls back to MY_MCP_TOKEN / OPENCLAW_TOKEN.

Generate OpenClaw Skills

Generate a single skill from the local bridge:

generate-openclaw-skill \
  --bridge-url http://127.0.0.1:8787 \
  --out ./skill \
  --skill-name my-mcp

Split tools into multiple skill directories by tool-name prefix:

generate-openclaw-skill \
  --bridge-url http://127.0.0.1:8787 \
  --out ./skills \
  --skill-name my-mcp \
  --split-by prefix

Optional discovery auth:

generate-openclaw-skill \
  --bridge-url http://127.0.0.1:8787 \
  --out ./skill \
  --token "$MY_MCP_TOKEN"

Generated output for a single skill:

skill/
  SKILL.md
  scripts/
    invoke.js
  schema/
    tools.json

Generated output for --split-by prefix:

skills/
  schema/
    tools.json
  my-mcp-search/
    SKILL.md
    scripts/
      invoke.js
    schema/
      tools.json
  my-mcp-ticket/
    ...

The generated wrapper uses:

• MY_MCP_TOKEN for the bearer token

• MY_MCP_BASE_URL for the local bridge URL

If MY_MCP_BASE_URL is not set, the wrapper falls back to the bridge URL used during generation.

OpenClaw Configuration

Recommended skill configuration:

{
  "skills": {
    "entries": {
      "my-mcp": {
        "enabled": true,
        "apiKey": "your-token-here",
        "env": {
          "MY_MCP_BASE_URL": "http://127.0.0.1:8787"
        }
      }
    }
  }
}

The generated SKILL.md declares:

• metadata.openclaw.requires.env = ["MY_MCP_TOKEN"]

• metadata.openclaw.primaryEnv = "MY_MCP_TOKEN"

That lets OpenClaw inject skills.entries.<skill>.apiKey as MY_MCP_TOKEN.

MCP Server Mode

The original stdio MCP server is still available:

node dist/index.js

Environment variables:

Examples

A checked-in generated example lives in examples/search-docs-skill/.

The bundled print skill now also follows the wrapper-based layout:

skills/xiaobai-print/
  SKILL.md
  scripts/
    invoke.js
  schema/
    tools.json
