arcade-mcp
MCP Server Framework and Tool Development library for building custom capabilities into agents.
Python developers building MCP tools that are not in a prebuilt catalogue — internal APIs, custom OAuth providers and domain-specific integrations.
You want ready-made tools rather than to write your own; the framework is for building what the prebuilt catalogue does not already cover.
About arcade-mcp
arcade-mcp is the Python framework for building Model Context Protocol servers and the tools that run inside them. It powers the 7,500+ prebuilt tools across 81 MCP servers at Arcade.dev, and is open-sourced so you can build your own.
Use it when you need MCP tools that aren't already in the prebuilt catalog: internal APIs, custom OAuth providers, domain-specific integrations.
The secrets (OAuth tokens, API keys, etc) are securely injected by Arcade into your tool call at runtime, so that your tool can authorize requests to upstream APIs, for example. The client and the LLM never see the secret values.
arcade-mcp is an open-source project written primarily in Python, with 1.0k stars on GitHub. It was last updated in September 2026.
