Keywords Everywhere in any MCP client

The server speaks standard MCP over streamable HTTP with OAuth 2.1, so any client that supports remote MCP servers can use it (Windsurf, Zed, JetBrains AI Assistant, Gemini CLI, Codex, custom agents built on the MCP SDKs, and more).

You need: An MCP client with remote (HTTP) server support and a Keywords Everywhere account with credits.

Setup

Add a remote MCP server with the URL https://mcp.keywordseverywhere.com/mcp (transport: streamable HTTP; the server has no stdio mode and no SSE stream).
If your client supports OAuth, connect and paste your Keywords Everywhere API key on the sign-in page that opens (the server supports dynamic client registration, PKCE and public clients, so no pre-registered client ID is needed).
If it does not, send your key directly: header Authorization: Bearer YOUR_KE_API_KEY on every request.

Discovery documents: /.well-known/oauth-protected-resource/mcp and /.well-known/oauth-authorization-server. Health: /health. A quick smoke test with curl:

curl -s https://mcp.keywordseverywhere.com/mcp -H "Authorization: Bearer YOUR_KE_API_KEY" -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_credit_balance","arguments":{}}}'

Credits and your account

You need a Keywords Everywhere account with a credit package. Every data tool spends credits from your own account at the same rates as the Keywords Everywhere API (1 to 5 credits per keyword or returned row, as shown in the table above); checking your balance, countries and currencies is free. Your API key is in the Keywords Everywhere settings (the same key the browser extension uses). Regenerating the key there instantly disconnects every assistant that used the old one.

Security and privacy

You sign in by pasting your API key on our page, so the key is never shown to the AI assistant. The server stores it encrypted (AES-256-GCM) and uses it only for the calls your assistant makes.
Every tool is read-only: nothing in your Keywords Everywhere account is changed by the assistant.
Access tokens expire after 3 hours and are refreshed silently for up to 90 days; disconnecting in your assistant, or revoking the API key, ends access at once.
The MCP server keeps request counters and short-lived operational logs only; it does not build a record of your keyword queries. See the privacy policy and terms.

Troubleshooting

The sign-in page says the API key is invalid: Copy the full key from your Keywords Everywhere settings again; keys are long and easy to truncate. The account must have an active credit package.
Connected, but no tools appear: Disconnect and connect again, then start a new chat. Some clients cache the tool list until the next connection.
A call fails with "insufficient credits": Ask for your credit balance, then top up in your Keywords Everywhere account.
Data for a keyword is missing: Google reports no volume for very rare keywords; try a broader phrase or a different country code.
Too many requests: The server allows 120 tool calls per minute per account. Wait a minute and retry.
