Verisk Underwriting MCP Server

Verisk Underwriting Intelligence is a provider-hosted MCP connector that brings Insurance Services Office (ISO) loss cost analytics into Claude. Announced May 5, 2026 alongside a sibling connector for restoration estimating, it gives underwriters and actuaries natural-language access to the same regulatory-grade ISO data they would otherwise pull from ISOnet, without switching between filing systems, indication reviews, and experience reports.

The connector exposes three underlying ISO data products: Loss Cost Activity (history of filed loss cost changes and their impact), Experience Index (loss experience trends and pure premium movement), and Indications Center (current ISO loss cost review details, including indicated and selected changes by coverage, class, and territory, plus trend selections). Users do not need to call these tools by name. Claude routes plain-English questions to the right data set based on whether the question is about history, emerging experience, or the latest indication.

The connector is provider-hosted by Verisk and surfaced through the Claude Connectors directory. It is restricted to Claude Enterprise workspaces and inherits the user's existing Verisk/ISOnet entitlements, so a user only sees lines of business and jurisdictions they are already licensed for. Verisk has not published a self-hostable GitHub implementation; setup is OAuth via the Verisk sign-in flow with MFA.

Tools

Verisk Underwriting Intelligence is a provider-hosted Claude Connector. There is no package to install and no self-hosted server URL to configure manually. It is enabled from inside Claude.

Prerequisites

• Claude Enterprise plan (the connector is not available on Free, Pro, or Team).
• Workspace admin has enabled the Verisk Underwriting Intelligence connector for your workspace.
• Active Verisk / ISOnet account with entitlements to the ISO loss cost products you intend to query (Loss Cost Activity, Experience Index, Indications Center).
• A registered MFA device or authenticator app for Verisk login.
• Outbound network access to claude.ai and Verisk authentication endpoints, with popups allowed on claude.ai for the OAuth handoff.

Steps

1. In Claude, open Settings, then Connectors (on some Enterprise workspaces this appears under Settings, Integrations).
2. Search for "Verisk Underwriting Intelligence" and click Connect.
3. You are redirected to Verisk's sign-in page. Enter your Verisk/ISOnet username and password, then complete MFA. Claude does not see or store the password.
4. After consent, you return to Claude with the connector active. The four underlying tools become callable automatically when you ask underwriting questions.

Disconnecting

Go to Settings, Connectors, Verisk Underwriting Intelligence, Disconnect. This revokes the OAuth token immediately. Access through Claude then stops matching your existing ISOnet entitlements.

Note on configuration JSON

Because this is a hosted Claude Connector (not a local MCP server), there is no mcpServers JSON block for Claude Desktop. Setup is entirely through the Claude UI on Enterprise.

• Pull the latest ISO indicated and selected loss cost changes for a specific line, jurisdiction, and coverage segment without logging into Indications Center directly.
• Investigate what is driving a current indication: trend selections, pure premium movement, and class or territory level signals.
• Compare filed loss cost activity over the last several review cycles to spot direction and magnitude of change in a state or program.
• Brief an underwriting committee on emerging experience trends across multiple jurisdictions in plain language, with the underlying ISO data cited.
• Triage which lines or states to prioritize for pricing review based on Experience Index movement.

• "What is the latest ISO indicated and selected loss cost change for commercial auto liability in Texas, and what are the main drivers?"
• "Summarize loss cost activity for homeowners in Florida over the last three review cycles."
• "Show me pure premium trend movement for general liability premises and operations in California for the most recent experience period."
• "Across the Midwest states, which commercial property territory segments have the largest indicated changes this cycle?"
• "Explain the trend selections driving the current businessowners indication in New York."

• Official, vendor-hosted connector built and maintained by Verisk, with data sourced directly from ISO rather than scraped or reformatted.
• Inherits existing ISOnet entitlements and MFA, so it fits inside an insurer's existing access controls and audit trail.
• Collapses three separate ISO products (Loss Cost Activity, Experience Index, Indications Center) into one conversational interface.
• Read-only by design, which keeps it suitable for regulated underwriting and actuarial workflows.

• Limited to Claude Enterprise; not available on Free, Pro, Team, or via local MCP clients like Claude Desktop or Cursor.
• Requires an active paid Verisk/ISOnet subscription with the right product entitlements; users without ISO access get nothing back.
• Public technical documentation is sparse. There is no published OpenAPI spec, tool schema, or self-hostable repo, so behavior must be discovered through use.

• Verisk Xactimate Estimating Intelligence connector for Claude (sibling MCP connector focused on property restoration estimates rather than ISO loss costs).
• Direct ISOnet web access for users who need full filing PDFs and circulars rather than conversational summaries.
• Internal actuarial data warehouses queried through a generic SQL or BI MCP server, for carriers that have already replicated ISO data in-house.
