Advanced Transport Strategies

# SSE-first (recommended): Try SSE, fallback to HTTP
npx mcp-remote http://localhost:3001/sse --transport sse-first

# SSE-only: Use only Server-Sent Events
npx mcp-remote http://localhost:3001/sse --transport sse-only

# HTTP-only: Use only HTTP requests
npx mcp-remote http://localhost:3001/mcp --transport http-only

# With custom headers
npx mcp-remote http://localhost:3001/sse --header "x-api-key: your-key"

2. Approve access to grant permissions

3. The server will issue an access token

4. All subsequent requests will use this token

Transport Strategies

When using mcp-remote, you can specify transport strategies:

# SSE only
npx mcp-remote http://localhost:3001/sse --transport sse-only

# HTTP only
npx mcp-remote http://localhost:3001/mcp --transport http-only

# Try SSE first, fallback to HTTP
npx mcp-remote http://localhost:3001/sse --transport sse-first
