Search, similarity, and analytics across approximately 20 million active, verified organizations across 232 countries and territories — exposed to AI agents via the Model Context Protocol.
The Global Organization Index (GOI) is ISTARI's curated, organization-level dataset, built through a multi-step validation pipeline that prioritizes quality over volume. See the GOI product documentation for dataset methodology, schema, and coverage statistics.
What this connector gives you¶
A single MCP endpoint that lets an AI agent run the same queries a GOI dashboard user would run, with all results scoped to that user's account and plan:
- Search companies by natural-language description, exact keywords, or a hybrid of both.
- Find lookalikes to one or more reference companies via embedding similarity, optionally steered with boost / penalize terms.
- Filter and list by country, state, region, district, municipality, NACE sector, organization type, size, and commercial-register attributes.
- Aggregate counts and distributions across any combination of those dimensions (one- or two-dimensional breakdowns, with optional time bucketing).
- Look up full company profiles by exact domain.
- Resolve free-text place names to canonical filter values.
Setup for Claude¶
- Sign up at index.istari.ai. The same account works for the GOI dashboard, the API, and this MCP connector.
- In Claude, go to Connectors > Browse Connectors > ISTARI GOI. And simply add it.
- Sign in when prompted. If you don't have an account at index.istari.ai yet, you can just create one during the sign-in process.
Plan access¶
New accounts start on the Standard plan — most functionality with monthly limits (see Connect). For higher quotas, see GOI access plans on the ISTARI technology page.
Standard plan quotas¶
All new accounts start on the Standard plan. Quotas reset on the first of each month (UTC).
| Capability | Tool group | Monthly limit |
|---|---|---|
| Search | search_organizations, find_similar_organizations, find_similar_with_steering, filter_organizations | 100 requests / 1,000 results |
| Fetch | get_organization_details | 100 requests / 1,000 results |
| Aggregate | aggregate_organizations | unlimited |
| Metadata | describe_filters, resolve_location | unlimited |
When a call would exceed the limit, the tool returns an error string beginning with Error:. A short consumption indicator appears in the response footer once you cross 80% of any limit.
To raise your quotas, see the GOI access plans on the istari.ai technology page.
A server-level burst cap (60 requests / minute per IP via Cloud Armor) also applies, independent of the monthly plan quota.
Troubleshooting¶
Monthly request quota exceeded— quotas reset on the first of the month (UTC). To raise your limits, see GOI access plans./healthreturns200 OKwith{"healthy": true, "service": "goi-mcp"}whenever the service is reachable.
For everything else: support@istari.ai.
