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 GOI MCP gives you

A single MCP endpoint that lets an AI agent run the same queries a GOI user would run, with all results scoped to that user’s account and plan:
  • Search organizations by natural-language description, exact keywords, or a hybrid of both.
  • Find lookalikes to one or more reference organizations 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 organization profiles by exact domain.
  • Resolve free-text place names to canonical filter values.
GOI MCP is undergoing review for publication in connector stores, including Claude and ChatGPT. Until it is listed there, request beta access with your ISTARI account.

​
Get access

  1. Sign up or sign in at index.istari.ai. The same account works for the GOI dashboard, the API, and GOI MCP.
  2. Request beta access. We enable approved accounts for early use.
  3. After approval, follow Connect to add GOI MCP in Claude, Cursor, or another MCP client.
Once GOI MCP is published in a connector store, you can add it from that store’s directory (for example Connectors → Browse Connectors → ISTARI GOI in Claude).

​
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).
CapabilityTool groupMonthly limit
Searchsearch_organizations, find_similar_organizations, find_similar_with_steering, filter_organizations100 requests / 1,000 results
Fetchget_organization_details100 requests / 1,000 results
Aggregateaggregate_organizations100 requests
Metadatadescribe_filters, resolve_locationunlimited
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. For full quota tables across dashboard, MCP, and API, see Pricing and limits. For higher quotas on a commercial plan, see GOI access plans or contact support@istari.ai. A server-level burst cap (60 requests / minute per IP) also applies, independent of the monthly plan quota to maintain fair usage.

​
Troubleshooting

  • Monthly request quota exceeded: quotas reset on the first of the month (UTC). To raise your limits, see GOI access plans.
  • /health returns 200 OK with {"healthy": true, "service": "goi-mcp"} whenever the service is reachable.
For everything else: support@istari.ai.
