HTTP transport hardcodes 60s fetch timeout, ignores MCP_TOOL_TIMEOUT

증상

The HTTP MCP transport has a hardcoded 60-second AbortSignal.timeout() on fetch requests that is independent of and ignores the MCP_TOOL_TIMEOUT environment variable. MCP tool calls that take longer than 60 seconds return empty {} responses silently — no error, no timeout message.

원인

Environment variable, configuration file, or initialization parameter missing, malformed, or incorrectly scoped.

해결법

None currently viable:

MCP_TIMEOUT — only controls server startup timeout
MCP_TOOL_TIMEOUT — controls protocol timeout but HTTP fetch aborts first
Patching the minified binary is fragile and lost on updates
