Secretctl: MCP server, setup and security
Secretctl is an open-source MCP server published on GitHub that lets an AI agent run commands with injected credentials without seeing plaintext secret values. Its repository has 11 stars and its last commit is from January 22, 2026 and it is licensed under Apache-2.0.
What Secretctl does
According to its repository: “Secrets manager that injects credentials into commands as environment variables so agents never see plaintext secrets, and sanitizes command output.”
The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. Secretctl is listed under Security, a category of 133 servers in the directory, where it ranks #91 by stars.
Topics declared by the repository: ai-agents, claude-code, cli, golang, local-first, secrets-management.
Installing and connecting Secretctl
No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.
It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: Go. Listed systems: macOS, Windows, Linux.
Security: what to check
Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.
None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Secretctl. 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 November 29, 2025, the forest6511/secretctl repository has 11 stars and 7 forks, with 3 open issues. It has more stars than 28% of the servers in the directory. Last change 9 months ago.
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
Verdict
Secretctl is still a modest project: read its code and compare it with the alternatives before using it.
