Smithery

What is Smithery?

Smithery is a registry of Model Context Protocol (MCP) servers, the connectors that let AI agents call external tools and services. The vendor's site says it is now part of Arcade and describes access to thousands of tools, including Arcade-built toolkits for services such as Slack, Gmail, GitHub, Notion and Stripe.

Key capabilities of Smithery

• MCP server registry: a browsable directory of MCP servers.
• Arcade toolkits: tool connectors for services such as Slack, Gmail, GitHub, Notion and Stripe.
• Managed authentication: the vendor says auth, credentials and sessions are handled for you.
• Browse and connect: find a server and connect it to your agent.

How Smithery works

A developer browses the directory, picks an MCP server or toolkit for the service they need, and connects it to an AI agent or assistant. The vendor says the platform handles authentication and sessions for the tools. Smithery announced that its MCP Proxy and managed identity features shut down on October 31, so confirm which features are still active before building on it.

Who uses Smithery?

Developers and teams building AI agents or assistants that need to use outside tools. The site does not state a target audience, and sign-up now leads to Arcade.

Smithery pricing

The site does not list pricing or plans; it links to sign-up for Arcade. Ask the vendor about current terms.

Smithery alternatives

Aider is a terminal coding assistant, so it uses tools rather than distributing them. Continue is an open-source coding assistant for IDEs that can connect to MCP servers. VoltAgent is a framework for building agents in TypeScript, which could consume servers found in a registry.
