- Runs on your computer with your user’s permissions (files, network, apps).
- The registry lists no key to fill in.
Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.

Common questions
Is Secret safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.6.0) reached the registry 4 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.
What can I use instead?

Secret
Let coding agents use your credentials without reading them.
A local credential CLI, a names-only MCP server, and a guard hook for coding agents.
Agents see key names, labels and paths, never values through the names-only interface. The CLI passes selected values directly to programs; the guard denies known store-reading operations.
How it works
- The agent asks for a credential by key name, not its value.
secrethands the selected value directly to the program's environment.secret runredacts loaded literal values from stdout and stderr.
Accident prevention, not a sandbox.
Install
Install or update the Secret CLI to the latest release.
Linux/macOS:
curl -fsSL https://raw.githubusercontent.com/avhn/secret/v0.6.0/install.sh | shWindows PowerShell:
irm https://raw.githubusercontent.com/avhn/secret/v0.6.0/install.ps1 | iexNo GitHub account or gh is needed; rerunning updates the installation.
See pins, paths and verification.
Use it
In your own terminal, stash a value with a hidden prompt. Agents can use show and run, but must never enter or retrieve values. These are illustrative paths:
secret stash ~/.secrets.env API_TOKENsecret show ~/.secrets.env secret run -f ~/.secrets.env --key API_TOKEN -- ./deploy.sh
Register names-only MCP using the installed executable's concrete absolute path and an exact human-approved store reference. Do not discover or read stores:
claude mcp add --transport stdio --scope user secret -- "/ABSOLUTE/INSTALL DIR/secret" mcp --store "file:/ABSOLUTE/STORE DIR/STORE.secret"Reconnect the client and verify list/show/diff/health. See Windows equivalents and client setup.
Use it to launch other MCP servers
For a human-configured client launcher, exec supplies selected values without filtering the server's stdio. It works on macOS, Linux and Windows; Windows long-lived exec shipped in v0.3.4. -f takes a plain store path, not file::
"/ABSOLUTE/INSTALL DIR/secret" exec -f "/ABSOLUTE/STORE DIR/.secrets.env" --key OPENPROJECT_API_TOKEN -- uvx openproject-ce-mcp@0.4.1This is not the names-only server or an agent retrieval route. Output is unfiltered and can disclose values. Review the server and configure this yourself; see client JSON, Windows paths and shutdown limits.
Next steps
- Set up clients, including the Claude Desktop MCPB and MCP Registry name
io.github.avhn/secret; see the release status for the currently published record. - Verify, update or roll back, with explicit Bash rollback at
compat/secret. - Windows support and limits.
- Security model and reporting.
Guard hook
The optional Claude Code and Codex plugins install the Bash guard and agent skill, not an MCP registration. Codex requires explicit hook trust in /hooks, including re-trust after changes. Install the protective ripgrep config and review the manual-hook instructions there. Go hooks remain inactive; installation and synthetic tests do not prove host fail-closed protection.
More workflows
See detailed usage, providers, labels, operator commands and templates, encrypted age stores, inactive 1Password scaffolding and pass stores.
Security limits
Literal redaction does not catch base64, URL encoding, substrings or other transformations. The guard cannot contain a determined agent, arbitrary child behavior or tools it never sees, including MCP search tools. Metadata can reveal names, labels, paths and provider account IDs. Treat this as one layer, not the boundary. Read the full threat model.
Development
See CONTRIBUTING.md for synthetic tests and PR guidance, AGENTS.md for agent rules and ROADMAP.md for milestones.
