Runno vs ScratchRun
A side-by-side look at the Runno and ScratchRun MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Runno for code execution work as a local process; choose ScratchRun for code execution as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Runno when
- You need dedicated capabilities in the Code Execution domain.
- You prefer a local stdio subprocess transport.
Choose ScratchRun when
- You need dedicated capabilities in the Code Execution domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
SCRATCHRUN_API_KEY.

Frequently asked questions
Runno is categorized under Code Execution and uses a local stdio subprocess. ScratchRun belongs to Code Execution and uses a local stdio subprocess. Pick Runno for code execution work and ScratchRun for code execution.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Runno has no declared pricing — check the project's own site. ScratchRun has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add runno and scratchrun as separate keys in the same mcpServers object, and your assistant will call tools from either one.
