Which MCP Server Should You Choose?
Choose Blackwall Mcp when:
You need dedicated capabilities in the Security domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (Freemium).
You have access to required keys: BLACKWALL_API_KEY, BLACKWALL_MODE.
You need dedicated capabilities in the Security domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).

Primary tools included: Policy enforcement on every file and shell action, Destructive command blocking and backup-before-write, Human approval gating via local GUI or API.
Pre-action risk gate for AI agents. One forecast tool the agent calls before any irreversible action (send money, run SQL, delete data); returns a risk score (0–100), reversibility class, named red flags from 28 failure modes, and a gate: proceed / confirm / human-required.
Runtime policy enforcement for AI agents - prevents accidental damage to your systems, unauthorized agent access and automates backup-before-write for any touched files.
Category & Scope
Tools & Capabilities Breakdown
Blackwall Mcp Tools (2)
forecast
Call this BEFORE taking ANY irreversible or high-stakes action — sending an email, making a payment, running SQL, deleting files or data, posting public content, calling an external API that changes state. It returns a risk score (0–100), a recommendation (GO / CAUTION / STOP), and named red flags. If the recommendation is STOP, do not take the action — surface the flags to the user instead. If CAUTION, confirm with the user first.
observe
Call this AFTER an action runs (or after deciding NOT to run it because BLACK_WALL returned STOP/HUMAN_REQUIRED) to report what actually happened. Closes the loop with the earlier forecast — BLACK_WALL compares your observation to the prediction to track accuracy and improve future forecasts. FREE — no tokens charged. Always call this if you have a forecast_id from a recent `forecast` call.
AI Runtime Guard Tools (6)
Policy enforcement on every file and shell action
Destructive command blocking and backup-before-write
