What it can do

Tool names and descriptions exactly as the server reported them on Nov 14, 2026. The maker wrote them, not us; we show them as plain text.

builderprime_list_projects

builderprime_get_project
Read one project and its customer/status/value fields. Requires projects.read.
builderprime_list_meetings
Read meetings beginning in a required date range (epoch milliseconds). Requires meetings.read; page is zero-based, limit max100.
builderprime_get_meeting
Read one meeting; requires meetings.read.
builderprime_list_employees
Read employees; requires employees.read. Pagination is zero-based, limit max100.
builderprime_get_employee
Read one employee; requires employees.read.
builderprime_list_meeting_types
Read meeting-types; requires meetingtypes.read. Pagination is zero-based, limit max100.
builderprime_get_meeting_type

builderprime_get_meeting_result
Read one meeting result; requires meetingresults.read.
builderprime_create_project
Create a project attached to an existing client opportunity; projects.create required. Show the exact fields to the user before calling. Executes immediately, may trigger vendor workflows.
builderprime_update_project
Modify only supplied project fields; projects.edit required. Status names must exactly match the account. Runs immediately; status changes may trigger workflows. No deletion/archiving.
builderprime_create_meeting
Create a meeting for a client opportunity. meetings.create required. Confirm dates, timezone, attendee and type before calling; writes immediately and vendor notifications may occur.
builderprime_update_meeting
Reschedule or edit meeting details; meetings.edit required. Runs immediately, no separate enforced approval. Blank location clears it. Read the existing meeting to check any unchanged start/end time before changing only one date.

Common questions

Is Builder Prime MCP by usefulapi safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (1.10.2) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

Builder Prime MCP by usefulapi

Hosted endpoint: https://builder-prime.usefulapi.io/mcp

Connect

Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://builder-prime.usefulapi.io/mcp.
Claude Code: claude mcp add --transport http builder-prime https://builder-prime.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:

"mcpServers": { "builder-prime": { "url": "https://builder-prime.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 Builder Prime credentials.

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

Verification limitation: real-account authentication, reads and writes have not been tested. Published example-tenant probes return a generic JSON 400 for missing and synthetic keys. This release passed mock integration and hosted Worker tests; real-tenant verification remains outstanding.
