- Add --header option to both wrapper CLI (cli.ts) and main CLI (index.ts)
- Support multiple headers with "HeaderName: Value" format validation
- Pass headers to HTTP and SSE transports via requestInit.headers
- Add parseHeaderPair function for proper header parsing
- Fix output truncation issue by removing forced process.exit(0)
- Update types to include headers in Args and TransportOptions
Usage: --header "Authorization: Bearer token" --header "X-Custom: value"
At the moment, the CLI tool expects that remote MCP servers, either
using SSE or streamable HTTP transport, have certain endpoints or
fragments -- `/sse` and `/mcp`, respectively. This is not part of the
MCP spec, nor should it be expected.
I also added a check to make sure a URL is provided if STDIO isn't
picked, erroring out if not.
