About agent-hanju/char-index-mcp

This tool is a Model Context Protocol (MCP) server that exposes character-level index-based string manipulation operations. It allows AI agents to perform actions such as substring extraction, character replacement, and length calculation using zero-based character positions. The server is written in Python and communicates via the MCP protocol.

Best for

Developers building MCP-based tools that require exact character-level text processing in AI agent workflows

Use cases

  • Extracting substrings by character index range
  • Replacing characters at specific positions
  • Computing string length and character offsets

Notes

2 stars on GitHub. Last updated 2026-04-02. Licensed MIT.

Pros

  • Lightweight Python server with minimal dependencies
  • Simple integer-based interface for precise string operations
  • Integrates seamlessly with MCP-compatible AI agents and tools

Cons

  • Very low community traction (only 2 GitHub stars)
  • Limited documentation and example usage
  • Only supports basic character-level operations, no regex or pattern matching

Not verified yet

No install recipe yet. We write one for Claude Code, Claude Desktop, Cursor, VS Code, Codex and ChatGPT when the server is in the official MCP registry with a package or remote address we can use.

Until then, follow the project's own README, or the setup the listing publishes under How to set it up.
