Frequently asked questions

Runno is categorized under Code Execution and uses a local stdio subprocess. Filesystem belongs to File Systems and uses a local stdio subprocess. Pick Runno for code execution work and Filesystem for file systems.

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. Filesystem is listed as free. Auth: no auth required. 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 filesystem as separate keys in the same mcpServers object, and your assistant will call tools from either one.
