Strategos.Ontology.MCP

MCP tool surface for Strategos ontology. Exposes ontology exploration, querying, and action dispatch as MCP tools for AI agent integration.

Installation

dotnet add package LevelUp.Strategos.Ontology.MCP

Requires Strategos.Ontology (included as a dependency).

MCP Tools

Four tools are auto-generated from your ontology definitions:

Tool Purpose
ontology_explore Browse domains, object types, actions, links, events, interfaces
ontology_query Query object sets with filters, link traversal, interface narrowing
ontology_action Dispatch actions (single or batch) through IActionDispatcher
ontology_validate Check a design intent against the frozen ontology graph

Tool Discovery

OntologyToolDiscovery generates tool descriptors enriched with constraint summaries:

var discovery = new OntologyToolDiscovery(ontologyGraph);
IReadOnlyList<OntologyToolDescriptor> tools = discovery.Discover();

Each action tool descriptor includes ActionConstraintSummary records with hard/soft constraint counts, enabling agents to assess action availability directly from tool discovery. It also carries typed requires and ensures predicate metadata in the closed Contracts 0.10 wire vocabulary. Arbitrary-precision integers and exact decimals remain canonical strings on the wire, and unknown predicate tags are rejected.

Features

  • Schema Exploration: 7 scopes (domains, objectTypes, actions, links, events, interfaces, workflowChains) with BFS link traversal
  • Object Queries: Composable filter, link traversal, interface narrowing, and include expressions
  • Action Dispatch: Single-object or batch execution routed through IActionDispatcher
  • Constraint Summaries: Hard/soft constraint counts embedded in tool descriptions for zero-shot agent reasoning
  • Typed Action Contracts: Lossless recursive requirements and guarantees in MCP _meta
  • Python Stubs: OntologyStubGenerator produces .pyi-style type stubs for agent tooling

Direct action-tool callers must bind the authenticated caller explicitly:

var principal = new ActionPrincipal("User", "user-42");
var result = await actionTool.ExecuteAsync(
    principal,
    objectType: "Order",
    action: "submit",
    request: request,
    objectId: "order-7");

Passing no principal is refused before the dispatcher is called. The MCP hosting package resolves this value from the authenticated request automatically.
