Description
https://github.com/mcp-shark/mcp-shark Site: https://mcpshark.sh/I built MCPShark, a traffic inspector for the Model Context Protocol (MCP).It sits between your editor/LLM client and MCP servers so you can: • See all MCP traffic (requests, responses, tools, resources) in one place • Debug sessions when tools don’t behave as expected • Optionally run “Smart Scan” checks to flag risky tools / configs
