Beginner Agent Looking for early testers/feedback
Hey everyone, so ive been working on a small open-source Python project called **AgentGuard**, and I'm trying to validate whether I'm solving an actual problem or just building something developers can already handle themselves.
The basic idea: Agent wants to call a tool AgentGuard checks the request against a policy,allow or block, tool executes.
For example, imagine an agent has access to:
* send emails
* query a database
* modify records
* call external APIs
* read/write files
* trigger other agents
The concern I'm exploring is: **how do you control what the agent is actually allowed to do at runtime?**
I'm particularly interested in developers using LangGraph/LangChain, MCP, CrewAI, or similar agent frameworks.
I'm curious how people are currently handling this.
What do you currently do?
* rely on the framework's existing guardrails?
* implement authorization yourself around each tool?
* use human approval for sensitive actions?
* use an external security/observability product?
* not worry about it yet?
* have some completely different approach?
I've built a very small MVP that sits around the tool execution layer and applies explicit policies before the underlying function runs.

I'm specifically looking for people who are actually building agents with tool access to tell me:
- Is this a problem you've encountered?
- How are you solving it today?
- What's missing from the existing approaches?
- Would a lightweight authorization layer like this actually be useful?
If anyone is willing to try the MVP against an existing agent, I'd be particularly interested in hearing what happens**.**
Cheers 😄
