FAQ from Okto Web3 MCP Server
How do I set up authentication?
Create a Google Cloud project, enable OAuth, generate OAuth client credentials (Desktop or Web app), download the JSON key file as gcp-oauth.keys.json, then run the auth command which opens your browser for Google login.
Where are credentials stored?
Credentials are stored globally in ~/.okto-mcp/. The OAuth keys file is placed there, and after successful authentication, credentials.json is saved in the same directory.
What dependencies are required?
You need a Google Cloud project with OAuth 2.0 credentials, an Okto account with API credentials (private key and SWA), and Node.js to run the server.
Does the authentication process require a specific port?
Yes, the OAuth callback uses port 3000. If port 3000 is already in use, you must free it before running authentication.
What transport or protocol does the server use?
The server follows the Model Context Protocol (MCP) and uses stdio transport for communication with Claude Desktop.
