Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "gitwhy-cli-gitwhy": {
      "command": "npx",
      "args": [
        "-y",
        "gitwhy-mcp"
      ],
      "env": {
        "GITWHY_API_KEY": "<GITWHY_API_KEY>"

Environment variables to set
GITWHY_API_KEYSecretGitWhy API key for cloud sync, publish, and PR comment features. Not required for local-only context saving.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
