What is Toolsdk Mcp Registry?
ToolSDK.ai is a free TypeScript SDK designed for developers building agentic AI applications that require seamless integration with external services and tools. It provides instant access to over 6,000 Model Context Protocol (MCP) servers through a unified API, eliminating the need for manual API configuration and allowing developers to connect to MCP servers with just one line of code.
The SDK simplifies the creation of AI-driven workflows by abstracting service-specific complexities into reusable components. Each MCP server is packaged as an npm module with typed inputs and outputs, enabling autocompletion and error checking during development. ToolSDK.ai hosts thousands of MCP servers as MCP-as-a-Service, providing a single entry point through an MCP Hub Server that acts as a proxy to connect all hosted servers.
ToolSDK.ai is ideal for developers of AI agents, automation workflow apps (similar to Zapier, n8n, or Make.com), and anyone building rapid prototypes for AI applications. It supports both OpenAI SDK and Vercel AI SDK integration, making it versatile for different development stacks. The platform also features an open GitHub registry where users can contribute their own MCP servers through structured JSON configurations.
The SDK supports dual protocol modes (stdio and Streamable HTTP), MCP OAuth 2.1 authorization for one-click auth without ENV configuration, sandbox execution for secure isolated server running, and includes a monitoring dashboard for real-time usage and performance metrics. The registry categorizes servers into 30+ categories including Developer Tools, Databases, Communication, Finance, Security, and more.

Frequently asked questions about Toolsdk Mcp Registry
What is ToolSDK.ai?
ToolSDK.ai is a free TypeScript SDK for connecting MCP servers to agentic AI apps. It allows developers to connect to over 6,000 MCP servers and AI tools with just one line of code, eliminating the messy integration and deployment challenges of managing multiple MCP servers manually.
How do I install ToolSDK.ai?
Install the SDK using npm or yarn by running 'npm install toolsdk' or 'yarn add toolsdk'. You can also install the registry package with 'npm install @toolsdk.ai/registry' to access MCP server lists in your JavaScript/TypeScript project.
Does ToolSDK.ai have a unified schema for all tools?
No, instead of a unified schema, each MCP server is standalone and uses its own unique key—similar to how Zapier works. This keeps things flexible while maintaining compatibility across the ecosystem, allowing you to connect directly to each server using its specific identifiers.
How does authentication work with ToolSDK.ai?
MCP tools use env-based auth by spec, supporting API keys and tokens via environment variables. ToolSDK also fully supports the Zapier App schema including OAuth, so any Zapier App can be converted into an MCP tool with OAuth working out of the box without ENV configuration once MCP OAuth 2.1 is fully implemented.
Can I add my own MCP servers to the registry?
Yes, you can add your own MCP servers through the GitHub registry at https://github.com/toolsdk-ai/awesome-mcp-registry. Fork the repo, create a new JSON file under the packages folder with your server's structured configuration, and submit it for inclusion in the registry.
What AI SDKs does ToolSDK.ai support?
ToolSDK.ai supports both the OpenAI SDK and Vercel AI SDK. You can use 'getOpenAISDKTool()' or 'getOpenAISDKTools()' for OpenAI integration, and 'getAISDKTool()' or 'getAISDKTools()' for Vercel AI SDK integration.
Do I need to run MCP servers locally?
No, ToolSDK.ai hosts thousands of MCP servers as MCP-as-a-Service, allowing you to connect to hosted MCP servers without running local code. You can use a single MCP server in clients like Claude Desktop or Cursor to access AI tools across the entire ecosystem.
What categories of MCP servers are available?
The registry includes 30+ categories: Uncategorized, Aggregators, Art & Culture, Browser Automation, Cloud Platforms, Code Execution, Coding Agents, Command Line, Communication, Customer Data Platforms, Databases, Data Platforms, Developer Tools, Data Science Tools, Embedded System, File Systems, Finance & Fintech, Gaming, Knowledge & Memory, Location Services, Marketing, Monitoring, Search & Data Extraction, Security, Sports, Support & Service Management, Translation Services, Travel & Transportation, Version Control, and Other Tools and Integrations.
How do I verify if an MCP server is runnable?
In the registry, verified and runnable tools are marked with a checkmark (✅) - there are 584 verified servers. Servers that cannot be run by the MCP client (with mock environment variables) are marked with an X (❌) - there are 3468 unverified servers. Look for the ✅ symbol to ensure the server has been validated.
What is the MCP Hub Server?
The MCP Hub Server is a single entry point to all hosted MCP servers provided by ToolSDK.ai. It acts as a proxy/server/router that automatically routes to your starred servers, streamlining access to preferred MCP servers via a single configuration point without needing to manage individual connection settings.
