mcp-probe
Interactive MCP protocol debugger and testing TUI
TLDR
Debug an MCP server via stdio
$ mcp-probe debug --stdio [command]
Debug via HTTP+SSE$ mcp-probe debug --http-sse [url]
Run compliance validation$ mcp-probe validate --http-sse [url] --suite all
SYNOPSIS
mcp-probe command [options]
DESCRIPTION
mcp-probe is an interactive debugger and testing toolkit for Model Context Protocol (MCP) servers. The TUI provides automatic discovery of tools, resources, and prompts, advanced fuzzy search, and multiple view modes for inspecting server responses.
It supports compliance testing with report generation in HTML, Markdown, JSON, and YAML formats, making it suitable for CI/CD pipeline integration.
PARAMETERS
debug
Launch interactive TUI debugger for an MCP server.validate
Run automated compliance tests against an MCP server.--stdio COMMAND
Connect to MCP server via stdio transport.--http-sse URL
Connect to MCP server via HTTP+SSE transport.--suite SUITE
Compliance test suite to run (all, initialization, capabilities, security, performance).
CAVEATS
Requires a running MCP server to connect to. Transport support depends on the server's implementation.
