Implements core computational tools including mathematical operations (sum), text processing (grep, SHA-256 hashing), and data validation utilities
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@MCP Local Serversum these numbers: 15, 23, 42.5"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
MCP Local Server
Minimal Model Context Protocol (MCP) server written in Python.
Features
Implements JSON-RPC stdio transport.
Tools:
sum: safely sum a list of numbers.grep_lines: filter lines containing a substring.sha256: compute SHA-256 hash of text.json_validate: validate data against a JSON Schema.
