Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to usefulapi.io, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Hosted MCP server that lets an assistant browse Open To Close properties, contacts, teams, notes and tasks, and create contacts or property notes.

What you can do: List and search agents, contacts, teams, tags, time zones and contact/file roles
List properties with team and agent summaries, plus property contacts, documents, notes and tasks
Read individual property notes and tasks
Create a contact record and add notes to a property
Check monthly usage, request a missing feature, upgrade or cancel the subscription
When to use it: Useful when you work in Open To Close and want an assistant to look up properties, contacts, tasks and notes, or to add a contact or property note without opening the app.
Requirements: Remote endpoint added by URL only; the server signs in with OAuth and the login page asks for Open To Close credentials. An API token is generated in the Open To Close Apps & API Dashboard, and usage and billing are per token. A free plan allows 50 tool calls per month.

Before you install

Two tools write data: creating a contact and adding a property note, which adds another note on each call, so confirm details first. Paid plans are billed per API token through a payment link, with no refund for the current period on cancellation. The integration can read transaction records.

Installation

In SourceWeft

Open Open To Close MCP by usefulapi in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fopen-to-close/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Open To Close MCP by usefulapi

Hosted at https://open-to-close.usefulapi.io/mcp.

Connect

Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://open-to-close.usefulapi.io/mcp.
Claude Code: claude mcp add --transport http open-to-close https://open-to-close.usefulapi.io/mcp, then run /mcp to log in.
VS Code: Add to VS Code.
Cursor and other clients: add the URL as a remote MCP server:

json

{  "mcpServers": {    "open-to-close": {      "url": "https://open-to-close.usefulapi.io/mcp"    }  }}

{  "mcpServers": {    "open-to-close": {      "url": "https://open-to-close.usefulapi.io/mcp"    }  }}

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, and the login page asks for your Open To Close credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/open-to-close/

Generate an API token in the Open To Close Apps & API Dashboard. Usage and billing are per API token. The integration can read transaction records and, when requested, create contacts and property notes.
