Giving an AI assistant a company lookup tool

An assistant that has to check a company should read it from a register, not recall it from memory. The Model Context Protocol (MCP) gives it a standard way to call such a tool.

What to return to the model

A useful tool answer tells the model more than the name:

• Status, so that it does not treat a dissolved company as active.
• The source and the retrieval time, so that it can say where the answer came from.
• A clear error when a register is down, so that it does not guess.

Connect EntityFeed

Get a free key on the home page, then add the server to a client that supports remote HTTP servers:

{
  "mcpServers": {
    "entityfeed": {
      "type": "http",
      "url": "https://entityfeed.com/mcp",
      "headers": { "Authorization": "Bearer ef_YOUR_KEY" }
    }
  }
}

initialize and tools/list work without a key. Tool calls need one.

Tools

• search_company: search by name or company ID.
• get_company: one company by ID.
