Overview

AI-generated overview

Hosted MCP server that lets an assistant read and write Gripp business data: companies, contacts, projects, tasks, hours, invoices and offers.

What you can do
  • List and filter companies, contacts, employees and tags
  • List projects, tasks, hours, offers and invoices, with paging and ordering
  • Fetch a single record by id and list the lines of an invoice
  • Register hours, create tasks and create contact persons
  • Check monthly usage, request a feature, upgrade or cancel the subscription
When to use it
Useful when you work in Gripp and want an assistant to answer questions about projects, unpaid invoices, registered hours or account managers, or to log hours and create tasks and contacts without opening Gripp.
Requirements
Remote endpoint, no local install. Connect with the server URL only; sign-in is via OAuth and the login page asks for a Gripp API key, which the server stores per user. The key requires application administrator rights in Gripp. A free plan allows 50 tool calls per month.
Before you install
Write tools create hours, tasks and contacts, and each call creates a new record, so repeats produce duplicates; confirm before running them. The server holds your Gripp API key and reads customer, employee and invoice data. Paid plans cost money and are billed through a payment link; cancellation runs to the end of the paid period with no refund for the current period.

Installation

In SourceWeft

  1. Open Gripp 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%2Fgripp/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

Gripp MCP by usefulapi

Use your Gripp account from Claude, Cursor, or any MCP client. Read companies, contacts, projects, tasks, hours, invoices, offers and employees, register hours, and create tasks and contacts. Hosted, no local install: connect with your own credentials.

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

Connect

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

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

On first connect you provide a Gripp API key (Gripp → Settings → API keys; you must be an application administrator). The server validates it and stores it per user. No keys go in config files.
