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 not yet listed in connector directories for Claude or ChatGPT. Add it as a custom connector — see Connect. Once store approval is complete, we will update the docs with one-click install instructions.

​
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. Submit the GOI MCP access request. No approval is needed: we email you the Client ID, Secret, and connection details.
  3. Follow Connect to add GOI MCP as a custom connector in Claude, ChatGPT, Cursor, or another MCP client.

​
Plan access

New accounts start on the Standard plan, most functionality with monthly limits (see Standard plan quotas). For higher quotas, book a demo to talk about Premium.

​
Standard plan quotas

All new accounts start on the Standard plan. Quotas reset on the first of each month (UTC). When a call would exceed the limit, the tool returns an error in the format Error [CODE]: message, for example Error [RATE_LIMITED_REQUESTS]: .... 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, book a demo or contact support@istari.ai. A per-IP safety limit of 60 requests/minute also applies on all GOI endpoints, independent of the monthly plan quota.

​
Troubleshooting

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