CLI Inspector

# mcp-cli A CLI inspector for the Model Context Protocol https://github.com/user-attachments/assets/4cd113e9-f097-4c9d-b391-045c5f213183 ## Features - Run MCP servers from various sources - List Tools, Resources, Prompts - Call Tools, Read Resources, Read Prompts - OAuth support for SSE and Streamable HTTP servers ## Usage ### Run without arguments ```bash npx @wong2/mcp-cli ``` This will use the config file of Claude Desktop. ### Run with a config file ```bash npx @wong2/mcp-cli -c config.json ``` The config file has the same format as the Claude Desktop config file. ### Run servers from NPM ```bash npx @wong2/mcp-cli npx <package-name> <args> ``` ### Run locally developed server ```bash npx @wong2/mcp-cli node path/to/server/index.js args... ``` ### Connect to a running server over Streamable HTTP ```bash npx @wong2/mcp-cli --url http://localhost:8000/mcp ``` ### Connect to a running server over SSE ```bash npx @wong2/mcp-cli --sse http://localhost:8000/sse ``` ### Non-interactive mode Run a specific tool, resource, or prompt without interactive prompts: ```bash npx @wong2/mcp-cli [--config config.json] <command> <server-name>:<target> [--args '{}'] ``` Examples: ```bash # Call a tool without arguments npx @wong2/mcp-cli -c config.json call-tool filesystem:list_files # Call a tool with arguments npx @wong2/mcp-cli -c config.json call-tool filesystem:read_file --args '{"path": "package.json"}' # Read a resource npx @wong2/mcp-cli -c config.json read-resource filesystem:file://system/etc/hosts # Use a prompt npx @wong2/mcp-cli -c config.json get-prompt filesystem:create_summary --args '{"text": "Hello world"}' ``` This mode is useful for scripting and automation, as it bypasses all interactive prompts and executes the specified primitive directly. ### Purge stored data (OAuth tokens, etc.) ```bash npx @wong2/mcp-cli purge ``` ## Related - [mcpservers.org](https://mcpservers.org) - A curated list of MCP servers
