MCP

Ontoly MCP exposes deterministic capabilities backed by the Query Engine.

The MCP runtime does not expose raw graph mutation and does not parse source. Every capability reads from SoftwareGraph.

When an LLM-capable client uses Ontoly MCP, LLM Enhancement is mandatory. MCP returns deterministic graph facts; the LLM-facing workflow must preserve evidence, confidence, and explicit fallback behavior. Non-LLM tools may call the same capabilities directly.

import { createMcpRuntime } from "@0xsarwagya/ontoly-mcp";
 
const runtime = createMcpRuntime(graph);
const response = runtime.execute({
  capability: "TraceExecution",
  input: { id: "fn:src/index.ts:main" },
});

If a History artifact is available, pass it into the runtime so temporal capabilities and Evidence Packs include repository evolution facts:

const runtime = createMcpRuntime(graph, { history });
