## Choose when

### Choose arcade-mcp if…

- License: arcade-mcp is MIT, fastmcp is Apache-2.0.
- Requirements: Min 4 GB RAM.
- Tags unique to arcade-mcp: ai, arcade-ai, mcp-framework, model-context-protocol.
- When you need to build detailed, custom interactions between your AI agent and a structured environment that requires specific context management capabilities through the MCP protocol.

### Choose fastmcp if…

- License: fastmcp is Apache-2.0, arcade-mcp is MIT.
- Pricing: The core FastMCP library is free to use, with no premium tiers available as it is an open-source project..
- Tags unique to fastmcp: agents, fastmcp, llms, mcp.
- Also covers LLM Frameworks.
- Use fastmcp if your project demands high-performance Model Context Protocol (MCP) server or client development in Python.

## When NOT to use arcade-mcp

- If your project does not involve interaction with an environment that relies on the Model Context Protocol for its core functionality, Arcade-MCP may offer unnecessary complexity.
- When working in environments where direct support and integration of tools are crucial, arcade-mcp might have less support compared to more mainstream AI agent frameworks.

## When NOT to use fastmcp

- Avoid fastmcp if your project strictly requires language support beyond Python, as it is solely designed for Python development.
- Do not select this tool when the need arises to adhere to licensing terms outside of Apache-2.0.
