Insurance at the speed of conversation.

What Is the Thimble MCP Server?

Connect your AI assistant directly to Thimble’s insurance platform.

Instead of navigating separate tools or writing API requests, brokers can describe what they need in plain language. The AI assistant handles the workflow and returns results directly in the conversation.

Who is this for?
Licensed insurance brokers who have an active Thimble broker account. A broker account is required to authenticate and use this server. If you are a licensed broker interested in selling Thimble insurance, you can request access at broker.thimble.com.

Features

The Thimble MCP server exposes the following capabilities.

Search Business Activities
Find covered activities by location and category. Check whether a client’s occupation or event type is eligible before requesting a quote.

Get Insurance Plans
Retrieve available plans for a specific activity and ZIP code. Returns plan names, coverage types, and descriptions.

Get Coverage Options
Retrieve customizable options— coverages, limits, deductibles, and add-ons — before creating a quote.

Create a Quote
Generate a priced quote for a client. Accepts contact details, business info, coverage dates, and plan options. Returns a quote ID and payment breakdown.

Usage Examples

Here’s what you can do once connected.

Example 1 — Search for covered activities

PROMPT
“What activities does Thimble cover for businesses in California?”

WHAT HAPPENS
The assistant calls thimble_search_activities with a California ZIP code and returns a list of covered occupations and event types available in that state.

EXAMPLE RESPONSE
Here are some covered activities available in California:

• Photography & Videography
• Personal Training & Fitness Instruction
• Yoga & Pilates Instruction
• Handyman & General Contracting
• Event Planning
• Tutoring & Educational Services
• Cleaning & Janitorial Services

… and more

Would you like to see insurance plans for any of these?

Example 2 — Generate a quote

PROMPT
“Get me a quote for a yoga instructor in Phoenix for one day, starting next Monday.”

WHAT HAPPENS
The assistant chains four tools in sequence:

1. thimble_search_activities — finds the activity ID for yoga instruction in the given ZIP code
2. thimble_get_insurance_plans — retrieves available plans for that activity
3. thimble_get_options — fetches coverage limits and add-ons
4. thimble_create_quote — generates the priced quote using your broker credentials

EXAMPLE RESPONSE
Here’s the quote I generated:

I found Yoga Instructors as a covered activity in Phoenix. To finalize a quote for one day starting Monday, I need a few details:

Required:

• Your name and email
• Business name (or your name if it’s a sole proprietorship under your name)
• Business address (street + ZIP — Phoenix has many ZIPs; 85001 is downtown)
• Estimated annual revenue
• Coverage time window (e.g., 9:00 AM – 5:00 PM, or all day)

After providing all details you will get a quote

Yoga for all — General Liability, $1M limit · Annual policy · May 4, 2026 → May 4, 2027 · Casa Grande, AZ

Would you like to proceed, or adjust the coverage details?

Example 3 — Full broker workflow

PROMPT
“I have a client who does commercial photography in Austin, TX and needs a week of coverage starting May 1st. Can you find plans and give me a quote?”

WHAT HAPPENS
The assistant handles the full workflow — searches activities, retrieves plans, gets options, and creates the quote — asking for any missing details (client name, email, business address) along the way.
