MCP Permission Guard — Pre-Action Authorization for AI Agents
Intent-based permission system with risk scoring, rule engine, and audit trail. Zero dependencies, pure Python stdlib.
The Problem
Agents execute destructive actions without guardrails. Binary allow/deny prompts don't work (93% auto-approved). The "lethal trifecta" — private data + untrusted content + external communication — creates risks no single tool can detect.

The Solution
MCP Permission Guard classifies tool calls into 14 intent categories, scores risk 0-100, evaluates rules, and produces deterministic allow/deny/ask decisions with full audit trail.
Tools (11)
Tool | What it does |
| Map tool call → intent category (14 types) |
| Score 0-100 with lethal trifecta detection |
| Add allow/deny/ask rule by intent |
| Full evaluation: classify + risk + rules → decision |
| Query decision history |
| Show all registered rules |
| Delete a rule |
| Global policy: allow_all / deny_all / ask_all / rules_based |
| Read current policy |
| Decision statistics |
| Clear all state |
