Error: API Streaming failed - MCP hub not available

[amanbuild]

Getting "API Streaming failed: MCP hub not available" when I try to start a session. The agent works fine when I run it directly from the terminal — the error only appears when routing through OpenACP. Any idea where to start debugging this?

Run openacp doctor first — it checks connectivity between OpenACP and the agent process and will usually pinpoint this. The "MCP hub not available" error typically means the agent's MCP server didn't start within the timeout window (default 10 seconds). Try increasing mcpStartupTimeoutMs in your config if you're on a slow machine. Also check that the agent binary is in PATH when running as the OpenACP service user (common issue when running as daemon vs. interactive shell).
