AI-Native by Design

Every Mesaplex tool is built for both human developers and AI agents. Discoverable, invocable, and parseable — out of the box.

🤖

MCP Server Mode

Every tool includes an mcp subcommand that exposes it as an MCP server. AI agents discover and use your tools automatically.

📋

--json Output

Every command supports --json for structured, machine-readable output. Perfect for CI/CD pipelines and AI agent parsing.

🔍

--schema Discovery

Run --schema on any tool to get a complete JSON schema of all commands, flags, and expected inputs/outputs.

🔗

Composable Pipelines

stdin/stdout composability, --batch mode, --quiet, --no-color. Chain tools together or pipe to AI agents.

Works with any MCP-compatible AI
