UK Parliament AI Assistant

Disclaimer: This is an unofficial, independent project. It is not created, endorsed, or supported by UK Parliament. All data is sourced from the publicly available parliament.uk APIs.

GitHub: ChrisBrooksbank/uk-parliament-mcp-lab

An MCP (Model Context Protocol) server that gives AI assistants access to UK Parliament data. Query MPs, Lords, bills, votes, committees, debates, and more through AI assistants like Claude Desktop and VS Code Copilot. Also includes a CLI for terminal access.

MCP Server for AI Assistants

Connect your AI assistant to 209 UK Parliament API tools for comprehensive parliamentary research.

Getting Started

Step 1: Configure your AI assistant (see Claude Desktop or VS Code below)

Step 2: Start a parliamentary research session:

• Use the /parliament slash command (in Claude Desktop or compatible MCP clients)
• Or say "Order Order" (like the Speaker) to initialize the session

This gives your AI assistant the context it needs to effectively use the 209 available tools.

Starting a Session

Say "Order Order" to initialize your parliamentary research session. This gives Claude the context needed to effectively use the 209 available tools.

If that doesn't work, copy and paste this system prompt:

You are a helpful assistant that answers questions using only data from UK Parliament MCP servers.

When the session begins, introduce yourself with a brief message such as:
"Hello! I'm a parliamentary data assistant. I can help answer questions using official data from the UK Parliament MCP APIs. Just ask me something, and I'll fetch what I can - and I'll always show you which sources I used."

When responding to user queries, you must:
Only retrieve and use data from the MCP API endpoints this server provides.
Avoid using any external sources or inferred knowledge.
After every response, append a list of all MCP API URLs used to generate the answer.
If no relevant data is available via the MCP API, state that clearly and do not attempt to fabricate a response.
Convert raw data into human-readable summaries while preserving accuracy, but always list the raw URLs used.

Parliament Research Skill (Claude Code)

If you use Claude Code, this repo includes a /parliament-research slash command that turns Claude into a Parliament research assistant.

Type /parliament-research followed by a natural language question:

/parliament-research How did Keir Starmer vote on climate?
/parliament-research When was Chelmsford mentioned in Hansard?
/parliament-research What bills about education are in progress?

Claude will pick the right CLI commands, run them, and present a sourced answer. The command file lives at .claude/commands/parliament-research.md.

Claude Desktop Setup

1. Open Claude Desktop
2. Click Settings → Developer → Edit Config
3. Add the following configuration and save with UTF-8 encoding:

{
  "mcpServers": {
    "uk-parliament": {
      "command": "uvx",
      "args": ["uk-parliament-mcp"]
    }
  }
}

4. Restart Claude Desktop
5. Open the Developer tab to verify the server is running

Note: This uses uvx which runs the package directly without installation. It automatically uses the latest version from PyPI.

Don't have uvx? Install it with: pip install uv or see uv installation docs

VS Code Setup

1. Press Ctrl+Shift+P to open the Command Palette
2. Select MCP: Add Server
3. Choose Command: Stdio
4. Enter: uvx uk-parliament-mcp
5. Press Enter

Start the Server

1. Press Ctrl+Shift+P again
2. Select MCP: List Servers
3. Click the server you just added and choose Start server

First Interaction

1. Open Copilot Chat in VS Code
2. Set Agent mode using the dropdown in the bottom-left
3. Select your preferred model (e.g., Claude Sonnet 4)
4. Click Configure Tools, and select all tools from the newly added MCP server
5. Try a prompt such as: "What is happening now in the House of Commons?"
6. Accept any permission request to allow the MCP call

What Can I Ask?

You can ask questions about virtually all aspects of UK Parliament data. Here are some key areas:

• Live Parliamentary Activity: "What's happening in the House of Commons right now?" or "What's currently being debated in the Lords?"
• Members of Parliament: "Tell me everything you know about Boris Johnson," "What are Sir Keir Starmer's registered interests?" or "Show me the voting record of member 4129"
• Bills & Legislation: "Show me details of bill 425," "What amendments were proposed for bill 425?" or "What publications exist for the Environment Bill?"
• Voting Records: "How did MPs vote on the climate change motion?" or "Show me Lords divisions on healthcare policy"
• Committees & Inquiries: "Which committees are investigating economic issues?" or "Show me evidence submitted to the Treasury Committee"
• Parliamentary Procedures: "Search Erskine May for references to Speaker's rulings" or "What are the oral question times this week?"
• Constituencies & Elections: "Show me election results for Birmingham constituencies" or "List all constituencies in Scotland"
• Official Documents: "Are there any statutory instruments about housing?" or "What treaties involve trade agreements?"
• Transparency Data: "Show register of interests for Treasury ministers" or "What are the declared interests categories?"

Power Tools

These high-level tools combine multiple API calls for common research tasks:

Tool	What it does
get_mp_profile(member_id)	Complete MP/Lord profile: bio, interests, voting record
check_mp_vote(member_id, topic)	How an MP voted on a specific topic
get_bill_overview(search_term)	Full bill info: details, stages, publications
get_committee_summary(topic)	Committee overview: evidence, publications
get_my_mp(postcode, topic)	Find MP by UK postcode with full profile

Note: get_mp_profile and check_mp_vote require a member_id (int). Search first with get_member_by_name().

Example:

Tell me everything about Keir Starmer

The AI will use get_member_by_name to find the member_id, then get_mp_profile to fetch biography, registered interests, and voting history in a single efficient call.

Ending Your Session

Start a new chat session to end the parliamentary research mode.

Prompting Tips

Note: Since AI is involved, some responses may be inaccurate. These tips help improve reliability.

✅ Initialize Your Session

Always begin your session with /parliament or say "Order Order". This ensures the AI assistant uses the correct tools and cites its sources properly.

🔄 Clear Context

Use the + icon (new chat) if:

• The AI seems stuck in a loop
• You want to reset the conversation context

🔗 Re-Display the API URL

While the AI is instructed to list source URLs automatically, you can ask for them again at any time. This is useful for troubleshooting or if you simply want to re-confirm the source for the last response.

You can ask:

Show me the API URL you just used.

Example response:

The API URL just used to retrieve information about Boris Johnson is: https://members-api.parliament.uk/api/Members/Search?Name=Boris%20Johnson

🧠 Combine Data from Multiple Sources

Example:

Has Chelmsford been mentioned in either the Commons or Lords?

The AI may:

• Query both Commons and Lords Hansard
• Combine the results
• Offer more detail if requested

🧾 See the Raw JSON

For debugging or to inspect the raw data structure, you can ask the assistant to show you the full JSON response from its last API call. This is particularly useful for developers who want to understand exactly what information the AI is working with before it is summarized.

Example prompt:

Show me the JSON returned from the last MCP call.

Output Formats

The CLI supports multiple output formats via the --format flag:

# Auto-detect: rich table in terminal, JSON when piped (default)
parliament members search "Starmer"

# Explicit formats
parliament members search "Starmer" --format table
parliament members search "Starmer" --format markdown
parliament members search "Starmer" --format csv
parliament members search "Starmer" --format json

# Select specific fields (case-insensitive matching)
parliament members search "Starmer" --fields "id,nameDisplayAs,latestParty.name"

# Raw JSON with full {url, data} wrapper
parliament members search "Starmer" --raw

# Pretty-printed JSON
parliament members search "Starmer" --pretty

# Just the data (strips url wrapper)
parliament members search "Starmer" --data-only | jq '.items[0]'

When using --fields, the CLI shows available fields on stderr if none match, so you can discover the correct field paths.

Global flags:

• --format / -f - Output format: json, table, markdown, csv, auto (default: auto)
• --fields - Comma-separated field paths for column selection (case-insensitive)
• --raw - Output full wrapper JSON (url + data), disabling auto-formatting
• --pretty / -p - Pretty-print JSON output
• --data-only / -d - Return only the data field, not the {url, data} wrapper

URL Transparency

Every API request logs the source URL to stderr, so you can always see exactly which Parliament API endpoint was called:

# URL appears on stderr, data on stdout
parliament members search "Starmer"
# stderr: GET https://members-api.parliament.uk/api/Members/Search?Name=Starmer

# Capture just the data (URLs go to stderr, not stdout)
parliament members search "Starmer" > results.json

This makes it easy to verify data sources, debug issues, or construct your own API calls.
