Open source alternatives to mcporter

mcporter

List, configure, authenticate, call, and inspect MCP servers/tools

mcporter is an agent skill from the OpenClaw project, listed on skills.sh. It lets an agent work with MCP servers directly through mcporter: list servers and their tools, read a tool's schema, call tools with key=value or JSON arguments over HTTP or stdio, and handle authentication and configuration. Like every skill, it is a SKILL.md file of instructions the agent reads when the task calls for it, so the agent knows which commands to run and what to avoid. It is free and open source in the openclaw/openclaw repository on GitHub.
