MCP Reference: apikeys.googleapis.com

Manages the API keys associated with developer projects.

A Model Context Protocol (MCP) server acts as a proxy between an external service that provides context, data, or capabilities to a Large Language Model (LLM) or AI application. MCP servers connect AI applications to external systems such as databases and web services, translating their responses into a format that the AI application can understand.

Server Setup

You must enable MCP servers and set up authentication before use. For more information about using Google and Google Cloud remote MCP servers, see Google Cloud MCP servers overview.

Server Endpoints

An MCP service endpoint is the network address and communication interface (usually a URL) of the MCP server that an AI application (the Host for the MCP client) uses to establish a secure, standardized connection. It is the point of contact for the LLM to request context, call a tool, or access a resource. Google MCP endpoints can be global or regional.

The API Keys API MCP server has the following global MCP endpoint:

  • https://apikeys.googleapis.com/mcp

MCP Tools

An MCP tool is a function or executable capability that an MCP server exposes to a LLM or AI application to perform an action in the real world.

Tools

The apikeys.googleapis.com MCP server has the following tools:

MCP Tools
apikeys_list_keys Lists the API keys owned by a project, including their metadata and restrictions.
apikeys_get_key Gets the metadata for a specific API key. Does not return the key string itself.
apikeys_get_key_string Retrieves the actual secret API key string. Treat as highly sensitive.
apikeys_create_key Creates a new API key in the specified project. You can optionally specify restrictions.
apikeys_update_key Updates the metadata, restrictions, or display name of an existing API key.
apikeys_delete_key Deletes an API key. The key can be restored using UndeleteKey within 30 days.
apikeys_undelete_key Restores an API key that was recently deleted.
apikeys_lookup_key Finds the parent project and resource name of the API key that matches the key string in the request.

Get MCP tool specifications

To get the MCP tool specifications for all tools in an MCP server, use the tools/list method. The following example demonstrates how to use curl to list all tools and their specifications currently available within the MCP server.

Curl Request 
curl --location 'https://apikeys.googleapis.com/mcp' \
--header 'content-type: application/json' \
--header 'accept: application/json, text/event-stream' \
--data '{
    "method": "tools/list",
    "jsonrpc": "2.0",
    "id": 1
}'
