# Overview

> GOI over the Model Context Protocol, search, similarity, and analytics across ~20M verified organizations, exposed to AI agents.

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](https://modelcontextprotocol.io).

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](/goi/goi_start_page) 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.

<Note>
  GOI MCP is undergoing review for publication in connector stores, including Claude and ChatGPT. Until it is listed there, [request beta access](https://index.istari.ai/goi-mcp-access) with your ISTARI account.
</Note>

## Get access

1. Sign up or sign in at [index.istari.ai](https://index.istari.ai). The same account works for the GOI dashboard, the API, and GOI MCP.
2. [Request beta access](https://index.istari.ai/goi-mcp-access). We enable approved accounts for early use.
3. After approval, follow [Connect](/mcp/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](/mcp/connect#standard-plan-quotas)). For higher quotas, see [GOI access plans](https://www.istari.ai/en/technology) 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`                                                                                  |                 100 requests |
| 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.

For full quota tables across dashboard, MCP, and API, see [Pricing and limits](/docs/pricing). For higher quotas on a commercial plan, see [GOI access plans](https://www.istari.ai/en/technology) or contact [support@istari.ai](mailto: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](https://www.istari.ai/en/technology).
* **`/health`** returns `200 OK` with `{"healthy": true, "service": "goi-mcp"}` whenever the service is reachable.
