The knowledge graph your AI agents can safely write to

Schema-first data platform with deduplication, field-level permissions and tamper-evident audit — plus a native MCP server so your agents work inside the rules, not around them.

Built for structured, trustworthy data

Most "agent memory" tools are a loose blob. Retesco gives agents a governed schema with rules that are enforced at the database — not in a prompt.

⬡

Declarative schema registry

Types, predicates and identity policies versioned as drafts → validated → published. Your data model is code, not convention.

⇄

Statements, not rows

Every fact carries provenance, validity windows and confidence — agents attach sources instead of overwriting blindly.

⚿

Field-level permissions

Groups get granular read/write rights down to a single predicate. An agent sees exactly what it may touch — nothing more.

✎

Tamper-evident audit

Hash-chained audit events for every mutation. Who changed what, when and why — provable, not plausible.

⧉

Deduplication & identity

Identity keys merge the same real-world entity across imports and agent writes — no parallel records for one person.

⛨

Tenant isolation by design

Postgres RLS enforced on every query — workspaces share infrastructure, never data. Hosted on a European, non-US provider.

MCP server, first class

Point Claude Desktop (or any MCP client) at your workspace with a scoped API token and the agent reads, creates and links entities through governed tools — with capability checks and audit on every call.

$ claude mcp add --transport http retesco https://mcp.retesco.com/mcp \
--header "Authorization: Bearer <YOUR_API_TOKEN>"

# create a scoped token in the app, then the agent calls typed tools:
entities.create(type_id:'person', fields:{full_name:'Alex Morgan'})
relations.create(subject_id:'<person-id>', predicate:'works_for', object_id:'<company-id>')
