MCX (Modular Code Execution)

Item: MCX (Modular Code Execution)
Rating: 30
Author: M8ven

An MCP server that enables AI agents to execute sandboxed JavaScript and TypeScript code instead of calling individual tools directly. It significantly reduces token usage by allowing agents to filter, aggregate, and transform data locally before returning results.

🚨

Secret credentials may flow to a network call

1 flow detected: SUPABASE_ACCESS_TOKEN. We can’t prove the destination matches the brand the credential belongs to.

⚠️

Tool annotations don’t match behaviour

1 read-only tool performs write/delete/exec — mcx_related (line 3660: IMPORT_REGEX.exec(content))

⚠️

Tool descriptions don’t match what handlers do

1 tool describes read intent but its handler mutates — mcx_related (line 3660: IMPORT_REGEX.exec(content))
