crewai - 💡(How to fix) Fix Proposal: MAI-1 tool resolver for structured agent tool discovery

What this proposes

A MAI1Resolver utility that lets CrewAI agents resolve tools from a MAI-1 contract registry rather than constructing them manually.

MAI-1 is a minimal JSON contract describing a tool's interface, reliability, and installation:

{
  "aid": "pypi-requests",
  "logic":  { "input_schema": {"type": "url"}, "output_schema": {"type": "json"} },
  "trust":  { "reliability_score": 0.99, "latency_ms": 85 },
  "action": { "install_cmd": "pip install requests" }
}

Proposed usage

from crewai import Agent, Task, Crew
from crewai.tools.mai1_resolver import MAI1Resolver

tools = MAI1Resolver.search("web scraping")   # returns List[Tool]
agent = Agent(role="Researcher", tools=tools)

The resolver fetches contracts from aiaam.xyz, a public registry of pre-compiled contracts for common libraries.

Why it might be useful

• Agents can discover and load tools dynamically without hard-coding tool definitions
• Contracts expose reliability scores and latency so agents can choose tools by quality
• No changes to existing CrewAI APIs — purely additive

Questions before writing code

• Is dynamic tool discovery from an external registry something CrewAI wants to support?
• Would this fit inside crewai/tools/ or better as an optional add-on package?
• Any concerns about the dependency on an external service?

Happy to discuss before writing any code. Feel free to close if it doesn't align with the roadmap.
