This official MCP server provides AI assistants with three read-only tools to calculate UK inflation adjustments, estimate take-home pay based on 2026/27 tax rules, and compare monetary amounts against public spending budgets.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http pound-one-mcp https://pound.one/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add pound-one-mcp --url https://pound.one/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable pound-one-mcp in your MCP settings.

Cursor configuration

  "mcpServers": {
    "pound-one-mcp": {
      "url": "https://pound.one/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{

    "pound-one-mcp": {
      "type": "streamableHttp",
      "url": "https://pound.one/mcp",
