# v0.27.0 Release Notes

> v0.26.9 -> v0.27.0

## Summary

Turns Agenvoy into a stdio MCP server so external agents can use, create, and share sandboxed script tools through a single connection. Unifies the tool contract between internal runtime and MCP by bridging through the existing tool registry instead of maintaining parallel implementations.
