Gibraltar Prediction Markets — MCP Server

Query the Prediction Market Regulations 2026 (LN.2026/176) in plain English from Claude Desktop, Claude Code, ChatGPT, Cursor, or any MCP client. Ask a question — "What must an application for authorisation include?" — and get back the exact, cited regulation text instead of a guess.

Built for lawyers and regulatory professionals who want the statute inside the tools they already use.

| Client | Guide | |--------|-------| | Claude Desktop | docs/claude-desktop.md | | Claude Code (CLI) | docs/claude-code.md | | ChatGPT (custom connector) | docs/chatgpt.md | | Cursor & other MCP clients | docs/cursor.md | | Claude API / Agent SDK | docs/api-sdk.md | | The law & data model | docs/concepts.md |

Quick start

The server is hosted at https://mcp.0xjb.dev/mcp — nothing to install. Connect from any MCP client:

Claude Desktop

1. Open Settings → Connectors (under your profile menu).
2. Click Add custom connector.
3. Name it (e.g. Gibraltar Prediction Markets) and paste the URL: https://mcp.0xjb.dev/mcp
4. Leave the OAuth Client ID blank — no sign-in is required — and click Add.
5. In a new chat, open the tools menu (sliders icon) and check the connector is enabled, then ask away.

ChatGPT

1. Enable developer mode: Settings → Apps & Connectors → Advanced settings → toggle Developer mode (requires a paid plan).
2. Go to Settings → Apps & Connectors → Create (custom connector).
3. Name it, set MCP server URL to https://mcp.0xjb.dev/mcp, authentication: None.
4. Save, then enable the connector in a chat via the + / tools menu. ChatGPT retrieves through the server's search and fetch tools.

Claude Code (CLI)

claude mcp add --transport http gibraltar-pm https://mcp.0xjb.dev/mcp

Cursor / other MCP clients

Add a remote (streamable HTTP) MCP server with URL https://mcp.0xjb.dev/mcp — see docs/cursor.md.

Local via npm (stdio)

Every client can also run the npm package locally — no build, no paths:

{
  "mcpServers": {
    "gibraltar-prediction-markets": {
      "command": "npx",
      "args": ["-y", "gibraltar-prediction-markets-mcp"]
    }
  }
}

# Claude Code CLI
claude mcp add gibraltar-prediction-markets -- npx -y gibraltar-prediction-markets-mcp

For local testing before publishing, see PUBLISHING.md and the per-client guides (node dist/index.js over stdio, or npm run start:http for ChatGPT/remote).

What you can ask

• "List the arrangement of the Prediction Market Regulations 2026."
• "What does regulation 12 say about approving contracts?"
• "Give me the checklist for an authorisation application."
• "Define 'prediction market contract'."
• "Which contracts can the Authority prohibit under regulation 14?"
• "Can operators accept stablecoins?" (regulation 22)

Tools

Ten tools; search + fetch also satisfy ChatGPT's connector contract.

| Tool | Purpose | |------|---------| | search(query, limit?) | Ranked keyword search; returns ids for fetch. | | fetch(id) | Full verbatim text by id (reg-12, schedule-2, definitions). | | get_regulation(number) | A regulation, 1–34, with its Part. | | list_regulations() | The full arrangement of provisions. | | get_part(number) | Every regulation in a Part, 1–7. | | get_schedule(number) | A Schedule, 1–3. | | get_definition(term?) | A defined term (reg 3); omit to list all. | | get_application_checklist() | Schedule 1 — application requirements. | | get_authorisation_conditions() | Schedule 2 — core conditions. | | about() | Metadata, source and status of this server. |

Every response carries its source citation and a not-legal-advice reminder.

Data model

One authoritative file, data/regulations.json, holds the verbatim text. Each unit is an addressable document with a stable id — reg-1…reg-34, schedule-1…schedule-3, and definitions (the 14 defined terms of reg 3). This single shape serves every tool. Full walkthrough in docs/concepts.md.
