Before you connect

The login page asks for your Follow Up Boss API key.

Find it in Follow Up Boss → Admin → API. Every user has their own key, with exactly the permissions of that user (an agent key sees only that agent’s contacts; a broker or owner key sees the whole account). Your key is used only to call the Follow Up Boss API on your behalf and to derive a private account id; it is never shown to anyone.

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Follow Up Boss API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Example prompts

Turn on the Follow Up Boss connector, then ask in plain words. The AI picks the tools.

Tools 29

ToolTypeWhat it does
fub_get_identityread
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_search_peopleread
Search people (contacts/leads)
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_get_personread
Get one person
Fetch one contact by id. Pass fields="allFields" to include custom fields and everything else. FUB: GET /v1/people/{id}.
fub_check_duplicate_personread
Check whether a person exists
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_list_eventsread
List lead 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_callsread
List calls
Logged phone calls with outcome, direction and duration. Filter by person or number. FUB: GET /v1/calls.
fub_list_text_messagesread
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_tasksread
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_appointmentsread
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_dealsread
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_pipelinesread
List deal pipelines
Deal pipelines with their stages (the stage ids that fub_create_deal / fub_update_deal take). FUB: GET /v1/pipelines.
fub_list_stagesread
List contact 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_usersread
List users (agents)
Users in the account (agents, brokers, lenders) — the ids to assign people, tasks and deals to. FUB: GET /v1/users.
fub_list_custom_fieldsread
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_action_plansread
List action plans
The account's action plans (drip campaigns): id, name and status. Gives the names for the actionPlanId values of fub_list_person_action_plans. FUB: GET /v1/actionPlans.
fub_list_person_action_plansread
List action plans applied to people
Which people are on which action plan, with the status of each assignment (e.g. "Running", "Paused"). Give personId for one contact's plans, or actionPlanId for everyone on one plan. For many contacts, list each active plan's people (limit 100; page with offset until _metadata.total is covered) instead of one call per contact. Shows classic action plans only; Automations 2.0 are in fub_list_person_automations when that tool is listed. FUB: GET /v1/actionPlansPeople.
fub_lead_source_reportread
Lead source report by agent
Count leads from lead sources (e.g. Zillow) per assigned agent, how many reached the closed stage(s) (conversion rate), and leads per lender user (e.g. Zillow Home Loans loan officers). Use it to count instead of paging through fub_search_people. The numbers approximate FUB's in-app Lead Source report, which has no API, and cover only the people the API key can see (use an owner, admin or broker key for the whole account). At most 100 FUB requests per call (one per count). FUB: GET /v1/people totals, GET /v1/users.
fub_send_lead_eventwrite
Send in a lead / 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_personwrite
Update a 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_add_notewrite
Add a note
Add a note to a contact's timeline. FUB: POST /v1/notes.
fub_log_callwrite
Log a call
Record a phone call made or received outside FUB, with its outcome. Does not place a call. FUB: POST /v1/calls.
fub_create_taskwrite
Create a task
Create a task on a contact, assigned to a user (assignedUserId or assignedTo is required). FUB: POST /v1/tasks.
fub_update_taskwrite
Update a task
Update a task — mark it complete, rename, retype or reassign it. FUB: PUT /v1/tasks/{id}.
fub_create_dealwrite
Create a 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_update_dealwrite
Update a 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_usage_statusmeta
Usage status (free-tier meter)
Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
fub_request_featuremeta
Request a missing feature
Tell usefulapi that the user needs something the Follow Up Boss tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
fub_upgrademeta
Upgrade to Pro (unlimited*)
Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Follow Up Boss (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $19/month or $190/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter.
fub_cancel_subscriptionmeta
Cancel the Pro subscription
Cancel the caller's Follow Up Boss Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run fub_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

Is this an official Follow Up Boss product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Follow Up Boss. The server calls the Follow Up Boss API with your own Follow Up Boss access, so it sees only the data that your account can see.

Can I connect Follow Up Boss to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your Follow Up Boss API key. See Before you connect for where to find it.

Do I put my Follow Up Boss key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Follow Up Boss API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Follow Up Boss credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Follow Up Boss API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Follow Up Boss.

Can the AI change my Follow Up Boss data?

Yes, if you approve it. 8 of the 25 Follow Up Boss tools can create or change data. The other 17 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Follow Up Boss server only. Cancel any time: Pro then runs to the end of the paid period. Run fub_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run fub_upgrade: it returns a Stripe Checkout link. To cancel, run fub_cancel_subscription. Pro continues to the end of the paid period.

What if a Follow Up Boss tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with fub_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
