March 21, 2025

API

• 🌱 Remote MCP server: You can now easily connect your AI agent to Riza's Code Interpreter using our new remote MCP server. For instructions on how to use it (including your auth key), visit the new MCP section of your Riza dashboard.
• ✨ Faster builds for custom runtimes: We've sped up build times for custom runtimes by up to a minute.
• ✨ Version 0.10.0 of client libraries: We released a new version of our Python, Node, and Go client libraries to reflect a minor change to possible status values returned from the API.

Open source

• ✨ SSE support in mcp-go: Our Go MCP framework now supports server-sent events (SSE), so you can create remote MCP servers using the framework.

API

• ✨ Code execution time metadata: For each code execution request, you can now see the execution time in milliseconds. Responses from the Execute Code, Execute Function and Execute Tool APIs return this value in the new duration field.

Self-hosted

We released v0.5.0 of our self-hosted code interpreter. Updates include all changes in the "API" section, plus:

• 🌱 Prometheus-compatible metrics endpoint: You can now access metrics from the new /metrics endpoint. See the Prometheus Metrics docs for details.
• ✨ Configure work queue size and timeout: For each Riza deployment, you can now configure the size of the work queue shared among workers, and the amount of time to wait for an item to be added to the work queue. See the docs for details.
