promptspeak-mcp-server
Pre-execution governance for AI agents. Blocks dangerous tool calls before they execute.
AI agents call tools (file writes, API requests, shell commands) with no validation layer between intent and execution. A prompt injection, hallucinated argument, or drifting goal can trigger irreversible actions. PromptSpeak intercepts every MCP tool call, validates it against deterministic rules, and blocks or holds risky operations for human approval — in 0.1ms, before anything executes.
When to use this
- You run AI agents that call tools (MCP servers, function calling, tool use) and need a governance layer between the agent and the tools.
- You need human-in-the-loop approval for high-risk operations (production deployments, financial transactions, legal filings).
- You want to detect behavioral drift — an agent gradually shifting away from its assigned task.
- You need an audit trail of every tool call an agent attempted, whether it was allowed or blocked.
- You operate in a regulated domain (legal, financial, healthcare) where agent actions must be deterministically constrained.
