The process server in the Pare project focuses on providing structured, typed command execution output for AI agents. Its design goals are clear, but security should be considered.
Pare Process is an MCP server for running command-line processes with structured, schema-validated JSON output instead of raw terminal text. It supports timeouts and signals, designed for AI agents to get type-safe data without brittle parsing.
Tools

Setup
Install via npm package @paretools/process with stdio transport. Requires Node.js >= 20. Configuration examples for various clients are in the repository's setup guides (e.g., Claude Desktop, Cursor).
Fit and risk
Not for
- Scenarios needing raw terminal text or ANSI formatting
- Simple use cases where unstructured output is acceptable
- Users not needing this specific server
Required permissions
- Permission to execute arbitrary commands (as configured)
- System permissions depending on runtime
Risks and side effects
- Malicious commands can cause damage
- Improper timeout settings may hang
- Dependency on Node.js environment
Troubleshooting
- Check Node.js version >= 20
- Ensure npx is available; on Windows try cmd /c npx
- Verify command and arguments in MCP client config
- If connection timeouts, increase MCP_TIMEOUT
Use cases
AI agents executing commands with structured results
Automated scripts needing reliable, parseable output
Reducing token usage for CLI tool calls
