Show HN: Hahooh – Give AI agents the power to build their own MCP tools

https://hahooh.xyz/download
2•hahooh•1h ago
I built Hahooh because I was tired of writing the same boilerplate every time I wanted to give Claude or a local agent access to a new database schema or a random REST API.

While there are many great MCP servers out there, they are often fragmented or require manual setup. I wanted to create a "WordPress for MCP" experience where:

1. Non-authed/Public tools: You can quickly bridge a public API to an agent. 2. Agent-Centric CLI: Instead of a human configuring everything, the CLI is designed so an agent can eventually say "I need access to this DB" and (with permission) create its own bridge. 3. Security: I’m using GCP Secret Manager for credentials and bcrypt for API key hashing.

The stack is Go (backend), Vue 3 (frontend), and a Go-based CLI.

I’m really interested in the "agent-as-builder" paradigm. If agents can build their own tools, the engineering bottleneck for AI workflows disappears.

I'd love to hear your thoughts on the security model and how you’re handling MCP server management.
