AI agents are flying blind.
Today's AI agents are remarkably capable — they can reason, plan, and execute complex workflows. But they share a critical weakness: they lack context. Enterprise data is scattered across dozens of tools, siloed in formats that agents can't access, and impossible to query in real time.
The result? Agents that hallucinate, make decisions on incomplete information, and require constant human intervention. The bottleneck isn't intelligence — it's context.
mantle is the missing layer.
mantle 1.0 is a semantic context layer that sits between your data and your AI agents. It connects to 42 data sources, builds a real-time knowledge graph with entity resolution, and serves quality-scored, token-optimized context via the Model Context Protocol (MCP).
One API call. Every data source. Perfect context.
What's in 1.0
42 Zero-Copy Connectors
Read your data in place — CRM, data warehouse, documents, chat, email. No ETL pipelines, no sync jobs, no data duplication. Your data stays where it lives.
Semantic Knowledge Graph
Automatic entity resolution and relationship mapping across every connected source. mantle understands that "John Smith" in Salesforce and "jsmith@acme.com" in Slack are the same person.
Quality-Scored Context
Every piece of context is scored for relevance, freshness, and reliability. Your agents receive only the signal, never the noise.
MCP-Native Delivery
Built on the Model Context Protocol from day one. Token-optimized payloads delivered in under 100ms. Works with any MCP-compatible agent framework.
Enterprise-Grade Security
SOC 2 Type II compliant. End-to-end encryption. Role-based access controls. Your data governance policies enforced at every layer.
Built for developers.
Five lines of code to add deep context to any AI agent. SDKs for TypeScript, Python, and Go.
What's next.
This is just the beginning. We're a team of three engineers who believe that the context layer will become as fundamental to AI infrastructure as the database is to applications.
mantle 1.0 is available now in early access. Free tier included — 1,000 queries per month, no credit card required.
