OCL Context Layer

OCL standard

OCL is an experimental open format for giving AI systems structured, scoped, and verifiable business meaning for Odoo.

An Odoo connector explains how to reach records. An OCL context pack explains what relevant records and fields mean, which tempting interpretations are wrong, what ambiguity must be resolved, and which safety boundaries still apply.

question -> OCL context -> AI reasoning + existing connector -> Odoo

Use OCL

Choose the surface that fits your product:

Route	Call	Benefit	Alpha availability
MCP for AI agents	get_context, resolve_noun, explain_field	Put scoped Odoo meaning directly in an agent's tool loop	Public example or invitation runtime
CLI	get-context "What is revenue?"	Inspect a context pack and its warnings immediately	Public examples now
Python validator	validate_entry(entry, schema)	Read and produce interoperable OCL documents	Available now
TypeScript integration	Five production operation shapes	Connect a product to the verified hosted runtime	Source alpha and invitation runtime

Clone and try the context behavior:

git clone https://github.com/Nantiai/ocl-standard.git
cd ocl-standard
python reference/python/ocl_examples.py get-context "What is revenue?"

The result asks which revenue definition applies and returns the paired warning against treating account.move.amount_total as universal revenue.

Add the example MCP to an agent

{
  "mcpServers": {
    "ocl-public-examples": {
      "command": "python",
      "args": [
        "/absolute/path/to/ocl-standard/reference/python/ocl_examples.py",
        "serve-mcp"
      ]
    }
  }
}

This local server demonstrates the real OCL tool contract using ten public candidate examples. It is not the commercial Odoo 19 runtime.

See Using OCL for the integration flow, MCP calls, CLI commands, SDK examples, response handling, and current access boundary. Connector and MCP implementers should freeze against the connector runtime contract and its conformance fixture. Hosted runtime clients can follow the verified alpha call guide. Developers can first try one live verified decision, then start a scoped seven-day trial without GitHub, package installation, Odoo credentials, or customer data. The GitHub request and email paths remain available as fallbacks.

This repository contains the open interoperability layer:

• JSON Schemas for semantic entries and request-scoped context packs;
• a dependency-light Python validator and TypeScript client shape;
• ten Odoo 19 candidate examples covering the major knowledge types;
• an executable conformance suite;
• an example-only resolver and MCP server;
• public benchmark methodology.

It does not contain nanti.ai's commercial registry, production assembler, verification harness, source fingerprints, private benchmarks, tenant overlays, memory, or unreleased ontology candidates.

Status

Version 0.1.0 is an experimental technical alpha. The format can change while independent implementations test it. The examples demonstrate the format; they are not the commercial verified registry and do not carry a lifetime guarantee.

Odoo 19 is the only current stock-version focus.

External developer alpha

Developers can now clone the standard, run conformance, integrate the example MCP server, and report an independent implementation. See the developer alpha guide.

The public alpha is an interoperability surface, not free bulk access to the commercial verified registry. A bounded verified runtime is live at https://api.context.nanti.ai; its native form immediately issues a scoped, expiring evaluation key.

Core idea

meaning -> evidence -> rule -> assertion -> applicability -> confidence

Facts do not become verified because an LLM wrote plausible JSON. A conforming document describes evidence and assertions. A registry operator separately decides which verification policy is sufficient for a release claim.
