Agentleak: MCP server, setup and security

What Agentleak does

According to its repository: “Local privacy testing for AI agents: scan code for PII and secrets, score execution traces across internal channels, redact text, and track new or fixed findings through MCP tools.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Agentleak is listed under Security, a category of 133 servers in the directory, where it ranks #93 by stars.

Topics declared by the repository: ai-agents, cli, crewai, eu-ai-act, gdpr, langchain.

Installing and connecting Agentleak

No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: Python.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Agentleak. That does not replace reading the code.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on June 21, 2026, the yagobski/agentleak repository has 11 stars and 1 forks, with 0 open issues. It has more stars than 28% of the servers in the directory. It received changes this month.

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
