Provides structured, provenance-backed context for Shopify applications by ingesting and analyzing data from app listings, websites, and help centers into a graph-based memory system.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@ContextBuilder (ctx)get the starter context for the Notify Me! app"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
ContextBuilder (ctx)
Context-as-a-Service MCP server for Hengam's multi-agent system. Maintains app-isolated, structured, provenance-backed context for Shopify apps and delivers "just enough context" to other agents.
Features
App-scoped context: Isolated context for 4 Shopify apps (Notify Me!, Subi, Discounty, Convi)
Agentic Graph Memory: Graph-based retrieval with multi-hop traversal, not just vector search
Hybrid delivery: Push starter context bundles + Pull targeted context slices
Observation Masking: Budget-aware compression with full transparency on what was included/excluded
Provenance tracking: Every statement traceable to source URL + snapshot timestamp + content hash
Configurable LLM: Provider-agnostic (OpenAI, Anthropic, Gemini) with editable prompt templates
Schema-validated: All data objects validated with Zod at boundaries
Quick Start
# Install dependencies
pnpm install
# Set up LLM API key (at least one required for refresh)
export OPENAI_API_KEY=sk-...
# or
export ANTHROPIC_API_KEY=sk-ant-...
# Run the MCP server
pnpm dev
# Run tests
pnpm testMCP Tools

Architecture
Ingestion → Extraction → Graph → Delivery
fetch summarize build push/pull
parse extract traverse mask
snapshot score validate provenancePipeline Flow
Ingestion: Fetch public web sources (listing, website, help center), parse HTML, create snapshots with content hashes
Extraction: LLM-powered structuring — summarize pages, extract concepts/procedures, score observations, detect conflicts
Graph: Build context graph with nodes (features, procedures, constraints, FAQs, entities) and typed edges (explains, depends_on, resolves, etc.)
Delivery: Serve context via push (starter bundles) or pull (targeted slices) with observation masking and provenance
Configuration
All configuration is in config/:
apps.yaml— App source URLs and crawl settingsmodel-profiles.yaml— LLM provider configs (model, temperature, rate limits)settings.yaml— Task bindings, budgets, masking thresholds, graph settingsprompt-templates/*.hbs— Handlebars templates for all 8 LLM tasks
