User Finds Workaround to Connect Executor MCP to Instinct via Vault Credentials

SuspiciousName666 · reddit · 2026-11-14

A Reddit user shared an unofficial way to hook the Executor MCP endpoint into Instinct, a personal assistant product. The trick is to store the MCP endpoint as a "login credential" in Instinct's Vault: set Name to Executor, Username to https://mcp.executor.sh/mcp, and Password to the API token. Then send a carefully crafted prompt in the chat instructing Instinct to mark it as an Agent project, read executor.sh's public docs, authenticate, and list available tools (without actually operating any services), returning an approval link when authorization is needed. The author stresses this is not a native integration—it goes through Vault credentials, isn't guaranteed to work with every MCP server, and has only been verified on the hosted version of Executor.
