    2. Streamable transport
    3. Custom transports
  3. Authorization
  4. Security
  5. Utilities
    1. Cancellation
    2. Ping
    3. Progress

Client Features

  1. Roots
  2. Sampling
  3. Elicitation

Server Features

TroubleShooting

See troubleshooting.md for a troubleshooting guide.

Backwards compatibility

See mcpgodebug.md for a list of backwards incompatible behavior changes and description how they can be temporarily undone.

Rough edges

See rough_edges.md for a list of rough edges or API oversights that can't be addressed due to our compatibility promise. We'll revisit these if/when we move to a v2 of the SDK.
