@toducthanh/housecallpro-mcp

MCP server and Claude Code plugin for the Housecall Pro public API. Manage customers, book jobs, create estimates, track invoices, handle leads and more — all from natural language in Claude Code.

Requirements

• Claude Code installed
• Housecall Pro MAX plan account
• A Housecall Pro API key (how to get one)
• Node.js 20+

Installation — 3 steps

Step 1 — Register the marketplace

/plugin marketplace add toducthanh/housecallpro-mcp

Step 2 — Install the plugin (skills)

/plugin install housecallpro-mcp@toducthanh

This loads the Housecall Pro skill into Claude Code — workflow guides, field formats, example prompts, and tool reference.

Step 3 — Register the MCP server with your API key

claude mcp add housecallpro --scope user \
  -e HOUSECALL_API_KEY=your_api_key_here \
  -- npx -y @toducthanh/housecallpro-mcp@latest

Replace your_api_key_here with your real API key.

Verify it's working

Restart Claude Code, then run:

/skills    ← should list housecallpro
/mcp       ← should show housecallpro connected

Then try a live test:

Use the housecallpro MCP to get my company information

Getting your API key

1. Log into your Housecall Pro account
2. Go to App Store → API Key Management → Generate
3. Copy the key and keep it secure

API access requires the MAX plan. If you get a 403 error, check your plan.

Workflow guides

Book a job for an existing customer

Claude Code will automatically chain these steps:

1. list_customers → find customer_id
2. list_customer_addresses → find address_id
3. create_job → create the job
4. update_job_schedule → schedule it
5. dispatch_job → assign a technician (optional)

Example prompt:

Find customer John Smith, get his first address, create a job there
scheduled for 2025-05-01 9am-10am with 60 min arrival window,
notify the customer, and dispatch to employee Mike Johnson

Book a job for a brand new customer

Create a new customer Sarah Connor, phone +1 555 999 0000,
add her address 123 Main St Austin TX 78701,
then book a job there for 2025-05-02 at 2pm for 2 hours

Create an estimate with options

Estimates use a two-level structure — Options first, then Line Items inside each Option.

Create an estimate for customer {customer_id} at address {address_id},
add an option called "Standard Package" with a labor line item at $150,
then approve it

Lead to job conversion

Create a lead for customer {customer_id},
show me the pipeline statuses,
move it to the next status,
then convert it to a job and schedule it for next Monday at 10am

Field formats

| Field | Valid format | Invalid | |---|---|---| | Dates | "2025-05-01T09:00:00" | "05/01/2025", "next Monday" | | Phones | "+1 555 123 4567" | "555-PLUMBER" | | Work status | "scheduled", "completed" etc | "done", "pending" | | Money | Integer cents — $150 = 15000 | 150.00 | | IDs | Non-empty strings | "" (empty) |

Valid work status values: unscheduled · scheduled · in_progress · completed · canceled

Fetch all pages

Several list tools support fetch_all: true to automatically retrieve all pages:

Fetch all customers with fetch_all true
Fetch all completed jobs with fetch_all true from 2025-01-01 to 2025-03-31

Supported on: list_customers, list_jobs, list_estimates, list_leads, list_invoices, list_employees, list_events, list_tags, list_materials, list_pricebook_services

Capped at 20 pages (~200 records) by default. Use explicit page + page_size for larger datasets.

Authentication

API Key (single-company use — recommended)

claude mcp add housecallpro --scope user \
  -e HOUSECALL_API_KEY=your_key \
  -e HOUSECALL_AUTH_METHOD=apikey \
  -- npx -y @toducthanh/housecallpro-mcp

OAuth 2.0 (multi-company / partner apps)

claude mcp add housecallpro --scope user \
  -e HOUSECALL_AUTH_METHOD=oauth \
  -e HOUSECALL_OAUTH_TOKEN=your_oauth_token \
  -- npx -y @toducthanh/housecallpro-mcp

Known limitations

• Pipeline moves forward only — you cannot set a lower-order status
• Availability/booking slot endpoints — use get_booking_windows for available slots
• Estimates use Options → Line Items (not direct like Jobs)
• Materials require material_category_uuid — call list_material_categories first
• Payment processing — not available via public API, use HCP dashboard
• fetch_all is capped at 20 pages by default
• Rate limits — not published by HCP; server auto-retries up to 3 times with backoff
