io.github.antikasPublished by GitHub account antikasv0.1.3Updated Oct 25, 2026
Read-only OpenIM search for institutional buy-side investment models and architecture.
The publisher's own server: model.tools — Zero-Auth Agent Utilities
Overview
A local, read-only MCP server that lets an assistant search the Open Investment Model reference for buy-side investment domains, services, entities and glossary
- What you can do
- Search all OpenIM model elements, optionally filtered by element type, and retrieve a single element by its OpenIM identifier. Map a stated buy-side architecture requirement to the most relevant model elements. List released exports such as schemas, ontologies and graph files, and return the canonical OpenIM identity, version, scope and official sources. Expose the identity and catalogue as MCP resources.
- When to use it
- Useful when an assistant needs to ground answers about institutional buy-side investment architecture in the OpenIM reference model, or to find which model elements relate to a stated requirement. It is a reference lookup, not an advisory or transactional tool.
- Requirements
- Node.js 20 or later, run locally via npx from the npm package. No API key, no accounts and no network calls at runtime; the model catalogue ships inside the package.
Installation
In SourceWeft
- Open Open Investment Model in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
README
OpenIM MCP server
Read-only, source-cited access to the Open Investment Model (OpenIM), the open reference model for institutional buy-side investment management.
The server searches and retrieves OpenIM Business Domains, Service Domains, Service Operations, canonical entities, relationships, glossary terms and generated model exports. Every response identifies the exact OpenIM release and links to the official versioned source. It does not provide investment advice, execute transactions or expose an implementation environment.
Run
Node.js 20 or later is required.
Generic MCP client configuration:
The server needs no API key and performs no network calls at runtime. Its catalogue is generated from the released OpenIM model when the package is built.
Tools
openim_search: search all model elements, optionally filtered by type.openim_get: retrieve one element by its OpenIM identifier.openim_map_requirement: find the model elements most relevant to a stated buy-side architecture requirement.openim_list_exports: list downloadable schemas, ontologies, graph files and other released artefacts.openim_get_identity: return the canonical OpenIM identity, version, scope and official sources.
The server also exposes openim://identity and openim://catalog as MCP resources.
Development
From the mcp/ directory in the OpenIM repository:
The build derives dist/model-index.json from ../model, ../metadata/openim.json and ../exports. It bundles the reachable stdio runtime into dist/server.js. The package version in package.json is injected into that bundle and generates server.json.
The quality command runs the source production audit, unit and MCP tests, bundle inventory, packed consumer test, identity scan and reproducible pack check. The packed consumer calls all five tools through the installed tarball and checks the model version and official source in every response.
The package carries OpenIM's MIT licence in dist/LICENSE. Bundled third-party packages are listed with their licence texts in dist/THIRD_PARTY_NOTICES.txt. Linked legal comments remain beside the entry point in dist/server.js.LEGAL.txt.
Licence
MIT. OpenIM is a reference model, not a standard, investment product or production system.
Privacy Policy
This server runs locally on your machine. The model content ships inside the package; the server has no accounts, sends no telemetry, and operates no backend service. Full policy: https://openinvestmentmodel.org/privacy/
