Read and write Less Annoying CRM contacts, notes, tasks, events, pipelines and groups. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"less-annoying-crm": {
"url": "https://less-annoying-crm.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"less-annoying-crm": {
"type": "http",
"url": "https://less-annoying-crm.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
The login page asks for your Less Annoying CRM API key.
Create one in Less Annoying CRM → Settings → Programmer API. The key's read/create/edit permissions apply, and API access requires a paid plan (or trial). Your key is used only to call the 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 Less Annoying CRM 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.
Turn on the Less Annoying CRM connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
lacrm_get_user | read | Get the current user Return the user who owns this API key — UserId, name, email and timezone. A cheap way to confirm the key works, and the UserId to use for AssignedTo. LACRM: GetUser. |
lacrm_list_users | read | List users List the users on the account that you can see (admins see all), with their UserIds — needed to assign contacts, tasks or filter by owner. LACRM: GetUsers. |
lacrm_search_contacts | read | Search contacts and companies Search (or list) contacts and companies. With no search_terms, returns everything visible, paged. Returns { HasMoreResults, Results }. LACRM: GetContacts. |
lacrm_get_contact | read | Get a contact or company Fetch one contact or company record with all its fields (emails, phones, addresses, custom fields, owner). LACRM: GetContact. |
lacrm_list_notes | read | List notes List notes, newest first by default — across the whole CRM, or for one contact. Filter by date range and author. LACRM: GetNotes. |
lacrm_list_tasks | read | List tasks List tasks due in a date range, optionally only incomplete/complete, for given users. If contact_id is given, ALL of that contact's tasks are returned regardless of dates or status. LACRM: GetTasks. |
lacrm_list_events | read | List calendar events List calendar events in a date range, filterable by user or calendar. If contact_id is given, all events attached to that contact are returned and other filters are ignored. LACRM: GetEvents. |
lacrm_list_pipelines | read | List pipelines List the account's pipelines (e.g. Sales Leads) with their statuses (StatusId, Name, IsActive) and optionally their custom fields. This is the setup, not the items — use lacrm_list_pipeline_items for those. LACRM: GetPipelines. |
lacrm_list_pipeline_items | read | List pipeline items List the items in one pipeline (deals, leads...), optionally only in given statuses or for given users. An empty status filter returns items in all ACTIVE statuses. LACRM: GetPipelineItems. |
lacrm_get_contact_pipeline_items | read | Get a contact's pipeline items All pipeline items attached to one contact or company, grouped by pipeline. LACRM: GetPipelineItemsAttachedToContact. |
lacrm_list_groups | read | List groups List the contact groups you can see (GroupId, Name, Sharing, Color), optionally with member counts. LACRM: GetGroups. |
lacrm_list_contacts_in_group | read | List contacts in a group List the contacts that are members of one group. Identify the group by group_id (preferred) or group_name — not both. LACRM: GetContactsInGroup. |
lacrm_get_contact_groups | read | Get a contact's groups List the groups one contact or company belongs to. LACRM: GetGroupsAttachedToContact. |
lacrm_list_custom_fields | read | List custom fields List the account's field definitions (name, type, options) for contacts, companies or pipelines — use the Name values as keys in custom_fields when creating/editing contacts. LACRM: GetCustomFields. |
lacrm_create_contact | write | Create a contact or company Create a new contact (person) or company record. For a person, company_name links them to that company (creating it if needed). Company names must be unique. If assigned_to is omitted, the record is assigned to the API key's own user (one extra GetUser call). Returns { ContactId }. LACRM: CreateContact. |
lacrm_edit_contact | write | Edit a contact or company Update fields on an existing contact or company. Only the fields you pass change; omitted fields are left alone. Multi-value fields (email, phone, address, website) are REPLACED by the list you pass. Set is_company=true when renaming a company. LACRM: EditContact. |
lacrm_create_note | write | Add a note to a contact Attach a plain-text note to a contact or company's history (newlines kept, HTML/markdown escaped). Returns { NoteId }. LACRM: CreateNote. |
lacrm_create_task | write | Create a task Create a to-do on a user's task list (date only, no time — use lacrm_create_event for timed things). Optionally attach it to a contact. Returns { TaskId }. LACRM: CreateTask. |
lacrm_edit_task | write | Edit or complete a task Update a task — including marking it complete (is_complete=true) or re-opening it (false). Only passed fields change. LACRM: EditTask. |
lacrm_create_event | write | Schedule a calendar event Create a timed (or all-day) event on your calendar, optionally with contacts/users as attendees. The timezone of start_date becomes the event's timezone. Returns { EventId }. LACRM: CreateEvent. |
lacrm_create_pipeline_item | write | Add a contact to a pipeline Create a pipeline item (deal, lead...) on a contact in a given pipeline and status, with an optional note. Returns { PipelineItemId }. LACRM: CreatePipelineItem. |
lacrm_update_pipeline_item | write | Move or annotate a pipeline item Move a pipeline item to another status (e.g. Prospect → Won) and/or add a note to its history. LACRM: EditPipelineItem. |
lacrm_add_contact_to_group | write | Add a contact to a group Add a contact or company to a group (creates a group membership). Identify the group by group_id (preferred) or group_name — not both. LACRM: CreateGroupMembership. |
lacrm_usage_status | 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. | |
lacrm_request_feature | Request a missing feature Tell usefulapi that the user needs something the Less Annoying CRM 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. | |
lacrm_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Less Annoying CRM (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. | |
lacrm_cancel_subscription | Cancel the Pro subscription Cancel the caller's Less Annoying CRM 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 lacrm_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Less Annoying CRM server only. Subscribe with lacrm_upgrade (it returns a Stripe Checkout link). Cancel any time with lacrm_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running lacrm_upgrade before then undoes the cancel. Or write to [email protected].
No. usefulapi is an independent service. It is not affiliated with or endorsed by Less Annoying CRM. The server calls the Less Annoying CRM API with your own Less Annoying CRM access, so it sees only the data that your account can see.
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.
The login page asks for your Less Annoying CRM API key. See Before you connect for where to find it.
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 Less Annoying CRM 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Less Annoying CRM 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 Less Annoying CRM.
Yes, if you approve it. 9 of the 23 Less Annoying CRM tools can create or change data. The other 14 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
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 Less Annoying CRM server only. Cancel any time: Pro then runs to the end of the paid period. Run lacrm_usage_status to see how many calls you used.
Ask the AI to run lacrm_upgrade: it returns a Stripe Checkout link. To cancel, run lacrm_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with lacrm_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.
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.
