Debug

Known issues

gotchaAWS credentials must be provided explicitly or via environment variables; the server does not automatically pick up default credential chains in all contexts.

fix

Set AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_REGION environment variables before instantiating the server.

affects: <=0.1.20

breakingThe import path changed in 0.1.10 from `awslabs_cloudwatch_appsignals_mcp_server` to `cloudwatch_appsignals_mcp_server`.

fix

Use `from cloudwatch_appsignals_mcp_server import AppSignalsMCPServer`.

affects: >=0.1.10

deprecatedThe `run_mcp_server` function is deprecated in favor of `AppSignalsMCPServer.run()` in version 0.1.15+.

fix

Replace `run_mcp_server()` with `AppSignalsMCPServer.run()`.
