Agentfit

agentfit-mcp

MCP server for @mukundakatta/agentfit. Lets Claude Desktop, Cursor, Cline, Windsurf, Zed, or any other MCP client estimate token counts and fit a chat history into a model's context budget on demand.

npx -y @mukundakatta/agentfit-mcp

Three tools:

• count_tokens — estimate tokens in a string or chat-message array, with per-model estimator families (openai, anthropic, google, llama, default).
• fit_messages — drop messages from a chat history until under a maxTokens budget. Supports drop-oldest, drop-middle, and priority strategies; honors preserveSystem, preserveFirstN, preserveLastN.
• list_estimators — list the built-in estimator families.
