Decision gist · record as of 2026-08-14
Yes. If you are building LlamaIndex agents and need to integrate tools from MCP servers, this package eliminates the integration work. It has low install friction, active maintenance, no known vulnerabilities, and a permissive license. Install it when you have an MCP server available and want agents to use its tools.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires an MCP server running and accessible at the specified URL or command.
- Low install friction with three straightforward runtime dependencies.
- Active maintenance with a recent release.

What it is and what it does
This package bridges LlamaIndex agents and the Model Context Protocol (MCP) ecosystem. It provides a client to connect to MCP servers, extract their exposed tools, and make those tools available to LlamaIndex agents for use in agentic workflows. It also works in reverse: it can wrap a LlamaIndex Workflow as an MCP server so other MCP clients can call it.
The package handles the mechanics of MCP communication—tool listing, resource access, prompt retrieval, and OAuth authentication—so you can focus on integrating external capabilities into your agent. It supports both synchronous and asynchronous operations, multiple transport types (HTTP, Server-Sent Events, stdio), and optional filtering of tools by name.
Use it for
- Equip a LlamaIndex agent with tools from an external MCP server (e.g., weather, database, file system).
- Expose a LlamaIndex workflow as an MCP service for other applications or agents to call.
- Build an agent that queries multiple MCP servers and combines their tools in a single reasoning loop.
- Implement OAuth-protected access to MCP servers requiring authentication.
- Convert a complex LlamaIndex workflow into a reusable tool for other systems via MCP.
