TokenTally by Harlo

Overview

TokenTally by Harlo is a Model Context Protocol server that counts tokens using o200k and cl100k encodings, truncates text to stay within token budgets, chunks content for retrieval-augmented generation, and estimates language model costs. Any MCP-compatible AI assistant can call these tools directly, letting the model decide when to apply them during conversations or agent workflows.

It runs as a hosted remote service at https://tokentally.mike-tusa.workers.dev/mcp, requiring only an API key for authentication and no local installation. The latest release is v0.1.0, available through the mcp.site directory.

TokenTally by Harlo is categorized under AI & Agents and integrates with all MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing on mcp.site to verify ownership, receive the Verified badge, and ensure information stays up to date.
