How to Set Up and Use MCP Man
MCP Man is a developer tool that acts as a Postman-style inspector and live tester for MCP servers, letting you browse a curated registry of 150+ servers, inspect their full tool schemas, and call tools with real arguments directly from your terminal. It provides CLI commands for searching the registry by name or tag, connecting to any running MCP server to introspect available tools, and executing live calls to see raw responses. Teams use it to evaluate new MCP servers before integrating them, debug tool behavior, and rapidly prototype agent workflows without writing any glue code.
Prerequisites
- Node.js 16+ installed
- npm or npx available in your PATH
- No mandatory API keys (individual server testing may require server-specific credentials)
- An MCP-compatible client such as Claude Desktop (optional, for in-session use)
Install mcp-man globally
Install the @aaglexx/mcp-man package globally so the `mcp-man` CLI is available anywhere in your terminal.
npm install -g @aaglexx/mcp-manLaunch the interactive UI
Run `mcp-man ui` to open the interactive browser interface that lets you search, inspect, and test servers visually.
mcp-man uiSearch the MCP server registry
Use the search subcommand to find servers by name or tag from the 150+ server registry.
mcp-man search github
mcp-man search --tag databaseInspect tools on a running MCP server
Connect to any MCP server by its launch command and immediately see every tool it exposes, including full parameter schemas and types.
mcp-man inspect "npx -y @modelcontextprotocol/server-memory"Call a tool live and see the response
Execute a specific tool against a running MCP server with JSON arguments and view the raw response. Useful for debugging and validation.
mcp-man test read_graph --server "npx -y @modelcontextprotocol/server-memory"MCP Man Examples
Client configuration
Add mcp-man itself as an MCP server in Claude Desktop so Claude can discover and query information about other MCP servers during a session.

Example terminal commands and agent prompts for discovering and testing MCP servers with mcp-man.
- "Search for MCP servers tagged with 'database'."
- "Inspect all tools available in the GitHub MCP server."
- "What parameters does the read_graph tool require?"
- "Show me all MCP servers in the registry that deal with file operations."
- "Test the create_entities tool on the memory MCP server with a sample entity."Troubleshooting MCP Man
mcp-man command not found after global install
Ensure npm's global bin directory is in your PATH. Run `npm bin -g` to find the directory and add it to your shell profile (e.g., `export PATH=$(npm bin -g):$PATH` in ~/.zshrc).
Inspecting a server fails with connection or spawn error
The server launch command passed to `mcp-man inspect` must be a valid, executable command. Ensure the target server's package is installed or accessible via npx. Test the server launch command independently first.
Server-specific tests fail with authentication errors
Some servers in the registry (like GitHub or Notion) require credentials. The integrated auth wizard will prompt for required tokens. Alternatively, pass them as environment variables before running the test command.
