Simple MCP Servers

Simple MCP Servers

The Simple MCP Servers collection offers developers a quick and hassle‑free way to expose custom functionality to Claude Desktop or any MCP‑compatible client. Each server is a single, self‑contained Python script that bundles its dependencies via PEP 723 inline metadata. This design eliminates the need for external files or virtual environments, allowing a server to be launched with a single command—either directly if the script is executable or through . The result is a lightweight, portable service that can be dropped into an existing workflow with minimal friction.

At its core, the repository ships three ready‑made MCP services that illustrate common use cases. The deer_to_bsky.py server translates URLs from the deer.social microblogging platform into Bluesky‑compatible AT URI formats, enabling seamless cross‑posting or data ingestion between the two ecosystems. The large_file_reader_mcp.py exposes a robust API for reading massive files in chunks, supporting line‑based iteration, head/tail extraction, byte‑level access, and pattern searching with contextual snippets—ideal for log analysis or data preprocessing tasks. Finally, time_god_mcp.py serves as a Scrabble word validator that ships the entire SOWPODS dictionary, making it useful for game development or educational tools that require quick word lookups.

These servers are built on the framework and leverage for request validation, ensuring that each endpoint receives well‑structured data before processing. The PEP 723 header declares the minimum Python version (≥ 3.11) and lists dependencies, which resolves automatically at runtime. This approach keeps the deployment footprint small while maintaining type safety and clear API contracts.

For developers integrating AI assistants into their tooling, Simple MCP Servers provide a plug‑and‑play mechanism to expose domain‑specific logic without writing custom adapters. A typical workflow involves adding a server entry to the Claude Desktop configuration, pointing it at the script’s location. Once registered, the assistant can invoke the server’s capabilities via standard MCP calls, allowing complex operations—such as large‑file streaming or cross‑platform URL translation—to be performed on demand within conversational contexts. The ability to host multiple lightweight services locally also reduces latency compared to remote APIs and gives developers full control over data privacy.

In summary, Simple MCP Servers solve the problem of rapid, dependency‑free deployment of custom AI assistant extensions. By packaging functionality into single Python files with inline metadata, they lower the barrier to entry for adding new tools, enable fast iteration on service logic, and integrate smoothly into existing MCP‑based workflows. The collection’s clear structure and ready‑made examples make it an excellent starting point for developers looking to extend Claude or any MCP client with bespoke capabilities.
