MCP Tools
MCP Tools is a Go-based CLI for interacting with MCP servers via stdio and HTTP transports, providing commands to list tools, call tools, launch an interactive shell, run a web UI, and manage MCP configurations across development editors.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
MCP tooling utilities. Developer tooling with local execution. Security depends on tools included. Audit tool definitions before production use.
⚡ Reliability
Best When
You are developing or debugging an MCP server and want a fast, frictionless CLI to call tools, inspect responses, and scaffold new servers without writing client code.
Avoid When
You need a production gateway, auth layer, or aggregator rather than a developer inspection tool.
Use Cases
- • Developers testing and debugging MCP server implementations by invoking tools from the command line
- • Exploring the capabilities of an unfamiliar MCP server interactively before integrating it into an agent
- • Managing MCP server configurations across VS Code, Cursor, Claude Desktop, and Windsurf from a single CLI
Not For
- • Production agent pipelines requiring a persistent gateway or proxy
- • Non-developer end users without CLI familiarity
- • Teams needing centralized multi-user access control or observability
Interface
Authentication
No built-in auth. Depends on target MCP server requirements. Environment variables and HTTP headers can be passed through to servers that require credentials.
Pricing
MIT licensed. Available via Homebrew and go install at no cost.

Known Gotchas
- ⚠ Binary installs as mcptools but aliasing as mcp conflicts with some systems; docs recommend mcpt alias
- ⚠ Mock server mode is for client testing only and does not persist state
- ⚠ No built-in auth pass-through for OAuth flows; only static headers and env vars supported
