Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "companydata": {
      "command": "npx",
      "args": [
        "-y",
        "@companydata/mcp-server"
      ],
      "env": {
        "COMPANYDATA_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport http companydata https://companydata.com/mcp/ --header 'x-api-key: your-value'

Or run it on your computer

claude mcp add companydata --env COMPANYDATA_API_KEY=your-value -- npx -y @companydata/mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "companydata": {
      "url": "https://companydata.com/mcp/",
      "headers": {
        "x-api-key": "your-value"
      }
    }
  }
}

Or run it on your computer

      ],
      "env": {
        "COMPANYDATA_API_KEY": "your-value"

}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "companydata": {
      "type": "http",
      "url": "https://companydata.com/mcp/",
      "headers": {
        "x-api-key": "your-value"

Common questions

Is CompanyData safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: COMPANYDATA_API_KEY, x-api-key

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 28 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

CompanyData.com MCP server

Model Context Protocol server that exposes the CompanyData HTTP API as tools: company search, company export (enrich), and location lookup (cities).

Product overview and setup guide: companydata.com/product/mcp-server/.

OpenAPI contract: https://companydata.com/openapi.json.

Hosted (no install)

Connect your MCP client to https://companydata.com/mcp/ and send your API key in the x-api-key header (get a key).

Claude Code:

claude mcp add --transport http companydata https://companydata.com/mcp/ --header "x-api-key: your-api-key-here"

Cursor (.cursor/mcp.json):

"mcpServers": { "companydata": { "url": "https://companydata.com/mcp/", "headers": { "x-api-key": "your-api-key-here" } } } }

Local (npx)

Requires Node.js 18+.

"mcpServers": { "companydata": { "command": "npx", "args": ["-y", "@companydata/mcp-server"], "env": { "COMPANYDATA_API_KEY": "your-api-key-here" } } } }

Build from source

git clone https://github.com/companydatacom/companydata-mcp-server.git

cd companydata-mcp-server npm install npm run build

Environment

Variable	Required	Description
`COMPANYDATA_API_KEY`	Yes	Sent as `x-api-key` on every request
`COMPANYDATA_API_BASE_URL`	No	API origin, default `https://app.companydata.com` (no trailing slash)

Copy .env.example to .env for local testing with npm run dev (load env in shell: set -a && source .env && set +a && npm run dev).

Tools

Tool	API
`company_search`	`GET /api/company/search`
`company_enrich`	`GET /api/company/export` with `ID` and `export=true`
`field_lookup`	`GET /api/cities`

Cursor & Claude Desktop

Build the project (npm run build).
In your MCP host (e.g. Cursor Settings → MCP or Claude Desktop config), add a server (adjust paths):

"mcpServers": { "companydata": { "command": "node", "args": ["/ABSOLUTE/PATH/TO/companydata-mcp-server/dist/index.js"], "env": { "COMPANYDATA_API_KEY": "your-api-key-here", "COMPANYDATA_API_BASE_URL": "https://app.companydata.com" } } } }

Reload MCP / restart Cursor if needed.

Smoke checklist

Server starts without errors (npm run build && node dist/index.js with env set).
MCP host lists tools: company_search, company_enrich, field_lookup.
company_search returns 200 payload for a simple query (e.g. search=BoldData).
field_lookup returns city suggestions (e.g. search=amst).

Development without a separate build step:

"mcpServers": { "companydata": { "command": "npx", "args": ["tsx", "/ABSOLUTE/PATH/TO/companydata-mcp-server/src/index.ts"], "env": { "COMPANYDATA_API_KEY": "your-api-key-here", "COMPANYDATA_API_BASE_URL": "https://app.companydata.com" } } } }

CLI

After npm run build, the package exposes companydata-mcp when linked (npm link) or when node_modules/.bin is on PATH.

Distribution

Hosted: https://companydata.com/mcp/ (Streamable HTTP, stateless). The website serves the same tools from a copy of src/tools.ts.
npm: @companydata/mcp-server.
Official MCP Registry: com.companydata/mcp (see server.json).
