What is a Role Brain?

A Role Brain is a persistent decision-pattern repository that captures the tacit knowledge and instincts of key personnel. When an executive departs, their Role Brain remains as a corporate asset, allowing a successor to operate at full capacity from Day 1.

How does StackFast differ from standard RAG implementations?

Standard RAG retrieves text without understanding context. StackFast provides a reasoning layer that applies judgment through structured logic, builds persistent Role Brains that compound over time, and enforces knowledge sovereignty through a 3-layer governance gate.

What is Knowledge Sovereignty?

Knowledge Sovereignty means your organization's intelligence never leaks into third-party training sets. Every brain entry is tagged for compliance and M&A readiness, with audit trails generated automatically for EU AI Act, SOC2, and HIPAA compliance.

How does StackFast reduce Key-Person Risk?

StackFast captures executive decision patterns, client relationship nuances, and institutional knowledge into structured Role Brains. When key personnel leave, their judgment and instincts remain as a corporate asset, reducing onboarding time for replacements and preserving institutional intelligence.

StackFast Governed Decision MCP

StackFast Governed Decision MCP exposes the public decision-support surface behind `stackfast.think.decide`, giving approved agents a bounded way to ask complex questions, evaluate artifacts, and produce evidence-aware decision packets without exposing protected internal reasoning names.

Who it is for

Agent builders, executives, operators, advisors, and enterprise teams that need traceable decision support rather than generic chat answers.

Problem it solves

It turns open-ended strategic, operational, technical, or artifact-review questions into structured options, gaps, hidden factors, confidence notes, and review boundaries that a human can inspect before acting.

Activation model

Assisted install through the StackFast MCP control plane with wallet authentication, tenant scope, MASK policy, bounded reasoning budget, and human review for high-impact recommendations.

Capabilities

governed decision analysis

mcp

Analyze a question, artifact, or decision packet and return decision options, gaps, confidence notes, and review boundaries.

Agent use
Calls stackfast.think.decide through the StackFast MCP control plane to run bounded governed decision analysis over a question, artifact, or decision packet. Use for traceable non-autonomous decision support with evidence pointers, candidate options, gaps, confidence notes, and render-boundary metadata.
