API Source

This MCP server uses the Legislative Yuan API v2 as its data source, providing information about Taiwan's Legislative Yuan bills and proceedings.

Tool Response Contract

Successful MCP tool calls return the raw JSON payload from the Legislative Yuan API. Failed tool calls return a machine-checkable JSON error envelope:

{
  "ok": false,
  "error": {
    "type": "http_status",
    "message": "Upstream API returned HTTP 404 for https://ly.govapi.tw/v2/bills/invalid_bill_number",
    "url": "https://ly.govapi.tw/v2/bills/invalid_bill_number",
    "status_code": 404,
    "response_excerpt": "not found"
  }
}

Current error type values include http_status, timeout, network_error, invalid_json, and unexpected_error.

Installation & Usage

Quick Start

Install and run the server using uvx:

uvx lymcp@latest

MCP Client Configuration

Add the server to your MCP client configuration (e.g., Claude Desktop):

PyPI

{
  "mcpServers": {
    "lymcp": {
      "command": "uvx",
      "args": ["lymcp@latest"]
    }
  }
}

GitHub

{
  "mcpServers": {
    "lymcp": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/narumiruna/ly-mcp",
        "lymcp"
      ]
    }
  }
}

Local Development

{
  "mcpServers": {
    "lymcp": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/ly-mcp",
        "lymcp"
      ]
    }
  }
}

Docker

{
  "mcpServers": {
    "lymcp": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "narumi/ly-mcp:latest"
      ]
    }
  }
}

Example Prompts

Once connected to the MCP server, you can ask your LLM questions like:

• "列出第11屆的所有法律提案" (List all bills from the 11th term)
• "查詢立法委員王美花的提案紀錄" (Look up legislator Wang Mei-hua's proposed bills)
• "以今天的台北日期為準，最近已發生的院會討論了哪些議案？" (Using today's Taipei date, what bills were discussed in the latest occurred plenary meeting?)
• "下一場已排程的院會是什麼時候？" (When is the next scheduled plenary meeting?)
• "查詢勞動基準法的修法歷程" (Look up the amendment history of the Labor Standards Act)
• "第11屆第1會期有哪些委員會會議？" (What committee meetings were held in the 1st session of the 11th term?)

For date-sensitive questions, distinguish:

• latest known: use the upstream default sort, including future scheduled records.
• latest occurred: only consider records whose relevant date is on or before the reference date.
• next scheduled: only consider records whose relevant date is after the reference date.

The server also exposes MCP prompts for common workflows: latest_plenary_meeting_bills, law_amendment_history, legislator_proposal_record, legislator_interpellations, and committee_meeting_lookup. Read lymcp://query-semantics and lymcp://workflow-reference for compact guidance on date semantics, filters, ID fields, and workflow steps.

Development

Prerequisites

• Python 3.12+
• uv package manager
• just command runner

Setup

git clone https://github.com/narumiruna/ly-mcp
cd ly-mcp
uv sync

Using Codex CLI

This repository includes .codex/config.toml for local Codex CLI development. When you start Codex CLI from the repository root, it can use the configured lymcp MCP server via uv run lymcp.

Running the MCP Inspector

just dev

Running Tests

# Run the default offline test suite with coverage
just test

# Run the default offline test suite directly
uv run pytest -v -s

# Run live tests against the Legislative Yuan API manually
just test-live

The default pytest configuration excludes tests marked live, so CI and normal local runs use fixture-backed samples from tests/data. Refresh those JSON samples intentionally when the live API shape changes.

Code Quality

# Run linter
just lint

# Run type checker
just type
