Research direction
Start by locating connectLocal and the runtime logger that emits the “server unavailable” message. Trace how status.error is captured and compare it with the fields currently logged. Done means local MCP spawn or connection failures include their reason in the log while retaining the server key and status.
Written by the indexing model from the issue text.
Description
When a local MCP server fails to spawn or connect (bad binary path, server exits on startup), the runtime log only shows:
WARN server unavailable { key: "my-server", type: "local", status: "failed" }
with no reason attached. The failure message is already captured in status.error by connectLocal (opencode mcp list does print it), but the log line drops it. With several MCP servers configured, it's undiagnosable which one broke and why.
Happy to send a PR adding the reason to that log line.
