## What it is
Arcade MCP is an open-source Python framework for building Model Context Protocol (MCP) servers and the tools that run inside them, with a decorator API covering the full MCP spec. It provides authorized tool calling with managed OAuth and secrets, tool-call evaluation against real LLMs, and one-command deployment.

## Use cases
- build a custom MCP server in python
- create tools for claude desktop or cursor
- add oauth-authorized tool calling to ai agents
- expose internal apis as mcp tools
- test llm tool-call accuracy
- connect custom tools to langchain or crewai agents
- host mcp servers for my organization

## When to choose
- you need MCP tools not available in prebuilt catalogs, like internal APIs or custom OAuth providers
- you want secrets and OAuth tokens hidden from the LLM and client
- you need vendor-neutral MCP servers that work with any client or agent framework
- you want to evaluate tool-call accuracy against real LLMs

## When to avoid
- you only need existing prebuilt tool integrations and never custom tools
- you want a non-Python MCP framework
- you need a full agent orchestration framework rather than a tool/server layer
