A toolkit for building with MCP

The Model Context Protocol makes it possible for AI apps to use tools and data, but building on top of it is more than tool invocation. You need sessions, OAuth flows, storage, reconnects, and framework integrations. mcp-ts takes care of that application layer so you can focus on what your app does.

Multi-user sessions

Persist and restore MCP connections per user across restarts with pluggable storage backends.

OAuth 2.1 handling

Full authorization flow — redirect, token exchange, and automatic refresh out of the box.

Framework adapters

Built-in adapters for AI SDK, LangChain, Mastra, and AG-UI Protocol.

ToolRouter

On-demand tool discovery across servers. Loads only what each request needs, reducing context bloat.

No vendor lock-in

Your MCP data stays in infrastructure you control — Redis, SQLite, Neon, Supabase, or memory.

CodeMode sandbox

Run programmatic tool calls inside a secure sandbox, avoiding expensive LLM tool-calling loops.

@mcp-ts/sdk

Core SDK with multi-backend session storage, OAuth 2.1 handling, SSE support, React and Vue hooks, and adapters for AI SDK, LangChain, and Mastra.

@mcp-ts/tool-router

On-demand tool discovery across multiple MCP servers. Reduces context bloat by loading only the tools needed for each request.

@mcp-ts/codemode

Sandboxed program execution for tool calling. Runs results inside a secure environment, avoiding expensive LLM tool-calling loops.

Remote MCP Server

A hosted Streamable HTTP endpoint providing instant access to 100+ app connectors, tool discovery, and CodeMode.
