Greptile Overview

Greptile Summary

This PR increases MCP tool execution timeouts from 1-5 minutes to a consistent 10 minutes across the system. The changes align MCP timeouts with the workflow execution timeout (DEFAULT_EXECUTION_TIMEOUT_MS), preventing premature timeouts when workflows take longer to complete.

Changes Made:

• Increased MCP_CONSTANTS.EXECUTION_TIMEOUT from 60000ms (1 min) to 600000ms (10 min)
• Increased MCP_CLIENT_CONSTANTS.CLIENT_TIMEOUT from 60000ms (1 min) to 600000ms (10 min) in both utils.ts and shared.ts
• Increased workflow MCP server fetch timeout from 300000ms (5 min) to 600000ms (10 min) in the serve route
• Updated all corresponding test cases and improved test descriptions

Impact:

• MCP tools invoking workflows will no longer timeout prematurely if the workflow takes more than 1-5 minutes
• All timeout layers (client, server, workflow execution) are now consistently set to 10 minutes
• Better user experience for long-running workflow operations accessed via MCP

Confidence Score: 5/5

• This PR is safe to merge - it's a straightforward timeout configuration change with comprehensive test updates
• The changes are simple, well-scoped, and properly tested. All timeout values are consistently updated across the codebase, and the tests verify the new values. The change aligns with existing workflow execution timeouts and addresses a real issue where MCP operations were timing out prematurely.
• No files require special attention
