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.

Market Pricing and Product Research MCP

Market Pricing and Product Research MCP exposes stackfast.market.* tools on the shared StackFast MCP control plane so agents can produce THINK-routed evidence-backed pricing and positioning packets without purchasing, publishing, or writing raw crawl data into brain/wiki.

StackFast UI

Who it is for

Founders, operators, procurement teams, consultants, agencies, consumers, households, professional buyers, and agent builders that need fresh cited pricing or product research before changing offers, buying tools, or publishing claims.

Problem it solves

It prevents stale model-memory pricing, uncited competitor claims, premature purchasing, and noisy raw research dumps from driving commercial decisions.

Activation model

Inquiry-first assisted setup with source policy, budget policy, local working DB, tenant scope, approval gates, and Service Desk/CRM routing rules.

Proof and source paths

Enterprise spec exists
Rev2 THINK router + BYOC local-lane spec exists
stackfast.market.* V1 tools are wired into the StackFast MCP control plane
THINK routing records primary framework, derived queries, model_lane_used=local, framework result, Anti-BS scores, and CORE quality scores
Local SQLite/libSQL working store keeps raw research out of brain/wiki
Purchase and promotion packets are approval-required and do not execute side effects
Team Hire pricing research is the first internal use case

Capabilities

market research namespace

mcp

Research live or manually supplied market sources, normalize offers, and produce cited evidence packets.

Agent use
stackfast.market.research creates local SQLite/libSQL research runs with source URLs, retrieval dates, normalized offers, claims, THINK routing, derived queries, local model-lane cost discipline, raw_body_included=false, and next-tool guidance.

routed framework kernels

mcp

Route research through StackFast THINK into HARD, PRO, RESEARCH, FOOD/HEALTH, or BRIDGE framework outputs.

Agent use
stackfast.market.hard_spec_match, pro_service_evaluation, research_evidence_validate, food_health_product_scan, and bridge_gap_analysis expose the THINK-selected framework result from a prior run. V1 keeps these local-lane and evidence-backed; FOOD/HEALTH image/OCR and lab-evidence override remain an explicit V1.1 depth lane.

pricing and packet builders

mcp

Create price-anchor, comparison, cost-saving, purchase, and promotion packets from cited evidence.

Agent use
stackfast.market.compare, price_anchor, cost_savings, purchase_packet, and promo_packet consume a prior run_id and return approval-ready packets. purchase_packet executes_purchase=false and promo_packet publishes=false.

Connector proof

Catalog is not the same as customer-ready.

This product only becomes market-ready after a real host mounts the entitled tools, a safe call succeeds, metering records the event, and a customer-safe receipt exists. Until then, the page shows the strongest proven status without rounding up.

Catalog

Runtime registry and product manifest are present.

Entitlement

Execution requires OAuth or storefront entitlement scope.

Callable

14 tool(s) declared with no missing V1 tools.

Metering

MCP calls are routed through the metering receipt path.

Customer validated

Pending fresh host-surface call receipt.

Runtime registry status

Primary registry

stackfast.ai/api/mcp

Status

live public mcp

Install gate

Callable and smoke-backed, but assisted-only until tenant install, approval-routing, live provider policy, and promotion rollback evidence are packaged.

Callable tools

stackfast.market.research
stackfast.market.hard_spec_match
stackfast.market.pro_service_evaluation

Missing or gated tools

No missing tools declared for the current V1 boundary.

Public MCP registry exposes stackfast.market.* with wallet authentication.
V1 never purchases, cancels, contacts vendors, or publishes promotions autonomously.
