FAQ
What is mcp-cli?
mcp-cli is a CLI inspector for the Model Context Protocol that lets you test and interact with MCP servers.
How do I run a server from an NPM package?
Run `npx @wong2/mcp-cli npx package-name args`. Add `--pass-env` if the server needs environment variables from your current shell.
Can I use mcp-cli non-interactively?
Yes. Use the non-interactive mode by specifying a command like `call-tool`, `read-resource`, or `get-prompt` with the server name and target, bypassing all interactive prompts.
How do I connect to a running server over SSE?
Use `npx @wong2/mcp-cli --sse http://localhost:8000/sse` to connect to a server already running with Server-Sent Events.
