# EasyMCP
EasyMCP is a complete rewrite of the model context protocol (MCP) in Python.
## Installation
```bash
uv add easymcp
```
## Usage
The high level API exposes a ClientManager class that can be used to manage multiple MCP servers.
```python
import asyncio
from easymcp.client.ClientManager import ClientManager
from easymcp.client.transports.stdio import StdioServerParameters
mgr = ClientManager()
searxng = StdioServerParameters(
command="uvx",
args=["mcp-searxng"],
)
timeserver = StdioServerParameters(
command="uvx",
args=["mcp-timeserver"],
)
servers = {
"searxng": searxng,
"timeserver": timeserver,
}
async def main():
# initialize the client manager
await mgr.init(servers=servers)
# list servers
print(mgr.list_servers())
# remove a server
await mgr.remove_server("searxng")
# add a server
await mgr.add_server("searxng", searxng)
# list tools - these are namespaced by server name automatically
# {server name}.{tool name}
print(await mgr.list_tools())
# call tool
print(await mgr.call_tool("timeserver.get-current-time", {}))
# list resources - these are namespaced by server name automatically
# mcp-{server name}+{resource uri}
print(await mgr.list_resources())
# read resource
print(await mgr.read_resource("mcp-timeserver+datetime://Africa/Algiers/now"))
await asyncio.Future()
asyncio.run(main())
```
## Core Features
- list tools/resources/prompts caching out of the box
- automatic cache invalidation on tool/resource/prompt change notifications
- out of the box support for parallel requests to servers
- full lifecycle management of servers
- dynamic server addition/removal
- namespaced tools/resources/prompts
- lightweight asyncio native implementation
## Why namespace tools?
Namespaced tools remove need to perform a lookup to find the correct tool. This means:
- faster tool calls
- tool calls can be routed across many MCP hosts at scale
- mcp servers do not need globally unique tool names
## Why namespace resources?
Resources are namespaced in a way that makes it easy to make a resource URI to a specific server. You can:
- check if a URL needs to be resolved via mcp by checking if it starts with `mcp`
- check what server to resolve the URI with
- ingest resources into a search system like elastic search without having to store metadata about the server
- completely eliminate the need to map URIs to servers via a database or lookup table
## Comparison of classes to other MCP libraries
| **easyMCP** | **modelcontextprotocol/python-sdk** | |
