AAAA Nexus MCP
Wire formally verified AI safety checks into Claude Code or Cursor agents without building your own guardrail stack.
Overview
AAAA-Nexus MCP is an MCP server for the Ship phase that exposes 75+ formally verified AI safety APIs to agents with pay-per-call USDC x402 billing.
What is this MCP server?
- 75+ formally verified AI safety API endpoints exposed as MCP tools
- Pay-per-call billing via USDC x402 with no account signup
- Python stdio MCP package (`aaaa-nexus-mcp`) for local agent wiring
- Hosted safety APIs at atomadic.tech instead of self-hosted policy engines
- 75+ API endpoints
- Pay-per-call USDC x402 billing
- Package version 0.1.1
What problem does it solve?
Indie builders cannot easily add production-grade, verified safety APIs to agent loops without custom infra and long vendor sales cycles.
Who is it for?
Solo builders shipping AI agents or copilots who need external safety APIs without signup-heavy enterprise platforms.
Skip if: Teams that require fully on-prem safety with no micropayments or who only need simple static content filters in-app.
What do I get? / Deliverables
After you register the stdio server, your agent can call verified safety endpoints on demand and you pay only per invocation via x402.
- Agent-callable tools backed by 75+ safety API endpoints
- Usage-based safety checks without platform signup
- Documented stdio MCP entry in your agent config

Common Questions / FAQ
Who is AAAA Nexus MCP for?
It is for indie and solo developers wiring Claude Code, Cursor, or similar agents to formally verified AI safety APIs at build and ship time.
When should I use AAAA Nexus MCP?
Use it when you are hardening agent features before launch and want pay-per-call access to 75+ safety endpoints instead of building verification in-house.
How do I add AAAA Nexus MCP to my agent?
Install the PyPI package `aaaa-nexus-mcp`, run it as a stdio MCP server with `python -m aaaa_nexus_mcp`, and add that command to your agent’s MCP config; fund USDC x402 calls per Atomadic docs.
