Overview

AI-generated overview

A local MCP server that searches current public UK company metadata from the official Companies House Public Data API.

What you can do
Search current public UK company metadata from the official Companies House Public Data API, per the registry description. The manifest lists no tools, so the exact operations are not documented. The README describes a broader Macaroon Network discovery router: search sale-ready products by intent, fetch feed metadata and category registries, discover MCP servers and reviewed source records, and execute paid products. Paid execution returns an x402 USDC payment challenge for the caller's own wallet to sign.
When to use it
When an assistant needs to look up current public UK company information from Companies House, or when working within the Macaroon Network marketplace to discover and run evidence-backed products.
Requirements
Runs as a local process over stdio, installed from PyPI and launched with uvx. No authentication, environment variables or headers are declared. The README mentions an optional MACAROONS_REGISTRY_URL override for local development and network access to the default registry.
Before you install
The README describes paid product execution settled in USDC on Base mainnet; the package does not hold a wallet or sign payments, so a separate wallet is needed and real funds can be spent. It returns payment challenges and accepts signed proofs on retry. The manifest declares no credentials, but the README names a registry URL override.

Installation

In SourceWeft

  1. Open Live UK Company Search in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

macaroonnetwork-mcp

MCP discovery router for Macaroon Network, a marketplace where agents find evidence-backed products and pay per successful query.

The payment rail exposed by this release is x402 using USDC on Base mainnet. The package never holds a wallet or signs a payment. It returns the exact x402 challenge for the caller's own wallet infrastructure to sign, then accepts that signed proof on the retry.

Tools

  • macaroons_search — search sale-ready products by natural-language intent. Free.
  • macaroons_metadata — retrieve free freshness and content-hash metadata for a feed target.
  • macaroons_categories — retrieve the canonical category registry and exact mapped-product counts. Free.
  • macaroons_discover_mcp — retrieve evidenced live Macaroon MCP servers and their transports. Free.
  • macaroons_sources — retrieve reviewed source and rights records, with explicit partial-coverage reporting. Free.
  • macaroons_execute — execute an x402 USDC product and receive the predicate-verified result and receipt.

Paying with x402

When a product needs payment, macaroons_execute returns an x402_payment_required result instead of hiding the challenge:

json
{  "x402_payment_required": true,  "resource_url": "https://api.macaroonnetwork.com/execute/...",  "amount_atomic": "3000",  "asset": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",  "network": "eip155:8453",  "pay_to": "0x33cc...",  "extra_name": "USD Coin",  "extra_version": "2",  "max_timeout_seconds": 60,  "x402_version": 2}

Sign the exact payment described by the challenge with your own wallet or Coinbase CDP infrastructure. Then call macaroons_execute again with identical arguments plus payment_signature. x402 exact settlement uses one signed retry; there is no invoice-polling flow.

Install

bash
pip install macaroonnetwork-mcp

Use with an MCP client

json
{  "mcpServers": {    "macaroonnetwork": {      "command": "macaroonnetwork-mcp"    }  }}

The default registry is https://api.macaroonnetwork.com. For local development, override it with MACAROONS_REGISTRY_URL.
