Search and filter contacts in Propstack CRM.
Use this tool to:
- Find contacts by name, email, or phone number
- List recent leads (sort by created_at desc)
- Find uncontacted leads (last_contact_at is null)
- Filter by broker assignment, status, tags, or GDPR status
- Search across all contact fields with 'q' parameter
The 'q' parameter searches across: first name, last name, all emails,
all addresses, and all phone numbers.
Phone search ('phone_number') ignores formatting — both 015712345678
and 0157-123-456-78 will match.
Returns paginated results. Use expand=true for full details including
custom fields.
Custom fields: pass 'custom_filters' as an object of custom-field-name →
value to filter by agency-specific fields (use list_custom_fields to
discover field names). Each entry becomes a cf_<name> query parameter,
e.g. { marketing_channel: "Website" }.
Data minimization (Art. 25 DSGVO): pass 'fields' with an array of contact
field names to return only those fields per contact (e.g. ["first_name",
"last_name", "email"]). Omit 'fields' to return the default set unchanged.
Unknown field names produce an error listing the valid options.

"Empfehlung", etc. with their IDs.

Look up a contact by phone number.
This is the go-to tool for voice agent caller identification. When a call
comes in, use this tool with the caller's phone number to instantly find
the matching contact.
Phone matching ignores formatting — all of these find the same contact:
015712345678, 0157-123-456-78, +49 157 12345678
Returns the matching contact(s) with key details. If no match is found,
the caller is unknown and you should create a new contact.
Search and filter properties (Objekte) in Propstack CRM.
Use this tool to:
- Find properties by address, ID, or exposé ID (use 'q' for fulltext)
- Filter by status, type, marketing type, or project
- Find properties in a price/rent range
- List properties by size, rooms, or construction year
- Filter by custom fields via the 'custom_filters' object (see below)
The 'q' parameter searches: unit_id, street, zip code, city, district, exposé ID.
Range filter pattern: 11 numeric fields each have _from and _to variants.
For example, price_from=200000 & price_to=400000 finds properties priced 200–400k.
Available range fields: price, base_rent, total_rent, property_space_value,
living_space, plot_area, number_of_rooms, number_of_bed_rooms,
number_of_bath_rooms, floor, construction_year.
Common queries:

- "All available rentals": marketing_type=RENT, status=<available_id from get_property_statuses>
- "Properties on market 90+ days": sort_by=created_at, order=asc
- "What's in Project X?": project_id=<id>
Custom fields: pass 'custom_filters' as an object of custom-field-name →
value (use list_custom_fields to discover field names). Each entry becomes
a cf_<name> query parameter, e.g. { energy_class: "A" }.
Always returns total count. Use expand=true for custom fields.
Data minimization (Art. 25 DSGVO): pass 'fields' with an array of property
field names to return only those fields per property (e.g. ["id", "title",
"price", "city"]). Omit 'fields' to return the default set unchanged.
