Available tools 22

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

fub

fub_add_note

Add a note to a contact's timeline. FUB: POST /v1/notes.

fub_check_duplicate_person

Check if a contact with this email or phone already exists anywhere in the account (even ones this user cannot see) and who it is assigned to. Use before adding a lead. FUB: GET /v1/people/checkDuplicate.

fub_create_deal

Create a deal in a pipeline stage (stage ids from fub_list_pipelines). Include userIds — a deal with no users is invisible to agents. FUB: POST /v1/deals.

fub_create_task

Create a task on a contact, assigned to a user (assignedUserId or assignedTo is required). FUB: POST /v1/tasks.

fub_get_identity

Who the credential belongs to: the account (id, domain, owner) and the authenticated user. A cheap way to confirm the API key works. FUB: GET /v1/identity.

fub_get_person

Fetch one contact by id. Pass fields="allFields" to include custom fields and everything else. FUB: GET /v1/people/{id}.

fub_list_appointments

Calendar appointments with invitees, type and outcome. Filter by person, user, or a start+end window (both required together). FUB: GET /v1/appointments.

fub_list_calls

Logged phone calls with outcome, direction and duration. Filter by person or number. FUB: GET /v1/calls.

fub_list_custom_fields

The account's contact custom fields: label, API name (customXxx), type and dropdown choices. Use the name as a key in customFields. FUB: GET /v1/customFields.

fub_list_deals

Deals (transactions) with stage, price, people, agents and commission. Filter by pipeline, user, person or status. The response metadata includes totalByStageId. FUB: GET /v1/deals.

fub_list_events

Lead activity: registrations, inquiries, viewed/saved properties, website visits, etc. Filter by person or type. Some events are only visible in the FUB app. FUB: GET /v1/events.

fub_list_pipelines

Deal pipelines with their stages (the stage ids that fub_create_deal / fub_update_deal take). FUB: GET /v1/pipelines.

fub_list_stages

Contact lifecycle stages (Lead, Nurture, Past Client, Trash…) with people counts — the names fub_search_people and fub_update_person take as "stage". FUB: GET /v1/stages.

fub_list_tasks

Tasks (follow-ups, calls, showings…). Filter by person, assignee, type, completion, or due window (due="today"|"overdue"|"upcoming"). FUB: GET /v1/tasks.

fub_list_text_messages

Text messages for a person or a phone number (message bodies may be hidden by FUB for privacy). FUB: GET /v1/textMessages.

fub_list_users

Users in the account (agents, brokers, lenders) — the ids to assign people, tasks and deals to. FUB: GET /v1/users.

fub_log_call

Record a phone call made or received outside FUB, with its outcome. Does not place a call. FUB: POST /v1/calls.

fub_search_people

Search contacts and leads. Criteria combine with AND. Name filters are partial matches. Newest first by default. People in the Trash stage are excluded unless includeTrash is true. Not every field is returned by default — pass `fields` (e.g. "allFields" or a comma list) for more. FUB: GET /v1/people.

fub_send_lead_event

Add a new lead or record activity on an existing one — FUB's documented way to create leads. FUB de-duplicates by email/phone (or use person.id to target a contact), routes the lead per Lead Flow, notifies the agent and runs action plans for Registration / Inquiry types. A 204 means the lead flow for this source is archived and the event was ignored. FUB: POST /v1/events.

fub_update_deal

Update a deal — move it to another stage, change price, dates, people or agents. peopleIds/userIds replace the full list. FUB: PUT /v1/deals/{id}.

fub_update_person

Update a contact's fields. CAUTION: `tags` REPLACES all tags unless mergeTags is true; `phones` and `emails` REPLACE the full list (send existing ones too). Setting contacted=true pauses action plans. source/sourceUrl cannot be changed after creation. FUB: PUT /v1/people/{id}.

fub_update_task

Update a task — mark it complete, rename, retype or reassign it. FUB: PUT /v1/tasks/{id}.
