Overview

AI-generated overview

Hosted BigTime connector that lets an assistant read staff, projects, clients, tasks, time, expenses, invoices and payments, run saved reports and log time…

What you can do
  • List and look up staff members, clients and projects, including project budgets, billing setup and assigned teams
  • List project tasks and staff tasks, and fetch a single task
  • Read timesheets, project time entries, single time entries and per-day hour totals
  • Read expense entries and expense reports
  • List issued and draft invoices, client invoices, payments and single invoices
  • Get saved report definitions and run saved reports with JSON filters
When to use it
Useful when you want to ask questions about BigTime project, time and billing data in plain language, such as hours logged per person, projects over budget, or draft invoices by client, and occasionally log time without opening BigTime.
Requirements
Remote MCP endpoint, no local install. Sign-in is via OAuth; on first connect you supply a BigTime API token and your BigTime firm id, which a firm administrator creates in BigTime. The server stores them per user. A free plan allows 50 tool calls per month; paid plans are available.
Before you install
The server holds your BigTime API token and firm id, so grant it only to a trusted host. bigtime_create_time_entry writes new time entries and can submit them for approval, so confirm before use. Paid plans involve payment through a checkout link, and cancelling does not refund the current period. Usage is metered per month.

Installation

In SourceWeft

  1. Open BigTime MCP by usefulapi in the dashboard and add it to a workspace.
  2. 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%2Fbigtime/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

Other MCP clients

Add this to your client's mcpServers config.

README

BigTime MCP by usefulapi

Use your BigTime account from Claude, Cursor, or any MCP client. Read staff, projects, clients, tasks, time, expenses, invoices and payments, run saved reports and create time entries. Hosted, no local install: connect with your own credentials.

Live endpoint: https://bigtime.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://bigtime.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http bigtime https://bigtime.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": {    "bigtime": {      "url": "https://bigtime.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 BigTime credentials.

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

On first connect you provide a BigTime API token and your BigTime firm id (a firm administrator creates the token in BigTime). The server validates it and stores it per user. No keys go in config files.
