What mcporter does

mcporter gives the agent command-line access to MCP servers and their tools. It can list servers, show a server schema, and call a tool with key-value arguments, function-style input, or JSON passed through --args. Calls can target an HTTP endpoint or start a server over stdio.

The skill includes OAuth commands and configuration management through auth and config list|get|add|remove|import|login|logout. It also exposes daemon controls, CLI generation, TypeScript emission, and inspection of a generated CLI. The default config path is ./config/mcporter.json; use --output json for machine-readable results.

Install it when the agent needs direct access to MCP tools from a coding workflow. It adds little for projects that do not use MCP servers.

What it helps with

  • list MCP servers and their available tools
  • inspect a server schema before calling it
  • send JSON arguments to an MCP tool
  • authenticate an MCP server with OAuth
  • generate a CLI or TypeScript client for a server

Example prompts for the agent

  • List the available MCP servers and show the schema for `linear`.
  • Call `linear.list_issues` with `team=ENG` and `limit:5`.
  • Check the mcporter config and return machine-readable JSON.

- Full URL: `mcporter call https://api.example.com/mcp.fetch url:https://example.com`
- Stdio: `mcporter call --stdio "bun run ./server.ts" scrape url=https://example.com`
- JSON payload: `mcporter call <server.tool> --args '{"limit":5}'`
