About Hydra

Hydra is an MCP server published by iflow-mcp in the AI category: context hydration engine for second brains — turns scattered agent work into a connected Obsidian vault. 100% Swift: SwiftUI app, CLI, and MCP server.

Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.

Install

From source
git clone https://github.com/iflow-mcp/mcp-hydra

This server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

Questions

About Hydra

How do I install Hydra?

No package has been published for this server, so install it from source: clone the repository and follow its README.

Is Hydra safe to use with an AI agent?

Its trust score is 47 out of 100 (fair). It passes 2 of the 3 static security checks run so far; the failures are listed above. It has no ConduID identity yet, so agent calls to it are not receipted.

Is Hydra still maintained?

The last commit was 7 months ago. That's long enough that you should check whether the maintainer is responding to issues before depending on it.
