Getting your agent authenticated with third-party services shouldn't require a custom connector for each one. Add Latchkey once and agents prepend latchkey to standard curl calls. Credentials are detected and injected automatically. They're stored encrypted on your machine, and never show up in logs or chat transcripts. 25+ services supported out of the box. Register any HTTP API at runtime. Works with Claude Code, OpenCode, Codex, and more. Open source software by Imbue.
Imbue's engineers have been thinking about a problem that didn't have a clean solution yet:
How do local AI agents authenticate with third-party services? Without making it painful for the developer, the end user, or anyone's privacy?
MCP servers work, but you need one for every service. Centralized connectors work, but now a third party sits between your agent and your data. Manual token management works, until you hand the tool to someone non-technical.
Latchkey was built to cut through that.
sent this to a couple of engineers i know who are building local agent setups. they've been duct-taping credential management together for months, this is right up their alley.
I use Claude Code and Cursor daily and I've learned that you can't just trust the output blindly - agents will tell you they implemented something and you'll find out later it was half done or the tests were never actually run. How does Vet handle cases where the agent made a reasonable interpretation of an ambiguous request? Does it flag those as potential issues or only catch clear deviations?
The credentials never showing up in logs or chat transcripts detail is the actually important thing here. I've seen agent setups where the auth storage is secure but the credential ends up in tool call output anyway - solved the wrong problem. Does token rotation work automatically? If a service refreshes the token mid-session does latchkey pick that up, or does the agent need to restart?

Who hunted Latchkey?
Latchkey was hunted by Alexander Tibbets. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
