Clerk, developed by Vulcanshen, is an MCP server tool built with Go, distributed as a direct binary download. It helps developers locally manage and organize their AI coding assistant sessions. Clerk connects to various AI providers, including Claude Code and OpenAI-compatible services, to summarize coding interactions, create searchable keyword indexes, and generate on-demand reports, all without sending user data off the local machine. This free tool is designed for privacy-conscious developers.

What does Clerk connect to?

Clerk integrates with multiple AI providers, notably Claude Code and any OpenAI-compatible service. This includes Groq, Gemini, OpenAI, and Ollama. It functions as an MCP server tool, operating entirely on the user's local machine. Its primary role is to process and manage AI coding session data, ensuring no information leaves the user's laptop. It acts as a local intermediary for AI coding assistant interactions.

Core features and tools

Clerk automatically summarizes AI coding sessions into local markdown files and creates a keyword index. It also generates on-demand reports from these summaries. The tool exposes three callable functions for AI clients: clerk-resume for context recovery, clerk-index-list for listing indexed items, and clerk-index-read for accessing specific indexed content. These tools enable structured management of coding assistant output.

Who is it for?

Clerk targets developers who utilize AI coding assistants and seek to maintain a local, searchable knowledge base of their AI interactions. It is ideal for those prioritizing data privacy and local control over their coding session summaries and reports. This is not the right fit if you require remote data storage or cloud-based session management.

How to get started

Authentication for Claude Code uses "Claude Code auth" and does not require an API key. For other providers like Groq, Gemini, and OpenAI, authentication involves setting an API key.

Use cases

• Automatically summarizing Claude Code sessions into local markdown files.
• Generating structured reports from session summaries, such as a weekly report using "clerk report --days 7".
• Enabling context recovery for AI sessions using the "clerk-resume" tool.

Clerk offers a local solution for developers to manage and organize their AI coding assistant sessions. It provides tools for summarizing, indexing, and reporting on AI interactions while keeping all data on the user's machine. This approach supports privacy and local control for developer workflows. Start by registering Clerk and configuring your preferred AI provider.
