[P0] B-2: Propagate tool-call AbortSignal and abort CDP work

Published: 9 hours ago

Repository: shaun0927/openchrome Author: shaun0927 # [P0] B-2: Propagate tool-call AbortSignal and abort CDP work Priority: P0 (SaaS blocker) Group: SaaS α Estimated Effort: 1-2 weeks Labels: saas, reliability, resource, p0 Problem: Even when the HTTP client disconnects, the tool call keeps running until timeout (120s), consuming resources and distorting billing. This causes OOM risk, race conditions, and can be a DoS vector. Current State: Only SSE cleanup exists, CDP calls do not accept AbortSignal, and no tokens are returned for completed requests. Proposed Approach: Introduce AbortController to propagate AbortSignal across the call path, detect HTTP client disconnects to abort, propagate aborts to CDP calls with graceful and forceful aborts, and enhance metrics and audit logs to reflect aborted calls and billing. Files to Change: Create ToolContext, cdpCall utility, tests; modify HTTP handling, MCP server, tools, metrics, and audit logger. Implementation Steps: Implement ToolContext and cdpCall, create AbortController in MCP server and wire signal propagation.
