pywss · Summary

Pywss is a lightweight Python web framework with built-in MCP server capabilities supporting SSE, StreamHTTP and MCPO protocols.

filesystem · Summary

A feature-rich MCP server for filesystem operations with dynamic directory access control.

pywss · Use cases

Building MCP servers with custom tools that need to expose both SSE and HTTP endpoints
Creating AI applications that require structured API documentation for MCP tools
Developing systems that need to handle high-volume concurrent MCP requests efficiently

filesystem · Use cases

Enable AI models to read and write project files during development
Allow Claude or other MCP clients to browse and analyze codebases
Provide secure sandboxed access to specific directories for content generation

pywss · Install

Installation

pip install pywss

Setting up an MCP server

from pywss import App
from pywss.mcp import MCPServer
from pydantic import BaseModel

class MyRequest(BaseModel):
    param: str

class MyMCPServer(MCPServer):
    @pywss.openapi.docs(description="My tool", request=MyRequest)
    def tool_my_tool(self, ctx):
        req = ctx.data.req
        self.handle_success(ctx, {"result": req.param})

app = App()
server = MyMCPServer()
server.mount(app.group("/mcp"))
app.run()
