Overview

AI-generated overview

Hosted MCP server for Collmex ERP: lets an assistant look up customers, vendors, products, stock, invoices, orders, accounting data and projects, and create…

What you can do
  • Search and read customers, vendors and the shared address book, including contact, bank and VAT fields
  • Search products and check currently available stock per product
  • Review customer invoices and credit notes, sales orders, payment terms and open items with overdue days and dunning level
  • Inspect accounting postings and account balances per fiscal year, filtered by account, cost centre or business partner
  • Review projects with budgets and rates, and recorded time-tracking activities
  • Create new customers and address-book entries, plus check usage, request features, upgrade or cancel the subscription
When to use it
Useful when you want an assistant to answer questions about Collmex business data, such as which invoices are still open, how much stock a product has, or what a customer was billed last quarter, without exporting data by hand. Also fits light data entry, like adding a new customer or address-book entry after checking for duplicates.
Requirements
Remote MCP endpoint added by URL only; no API key or Authorization header in the client config. Sign-in uses OAuth, and the login page asks for your Collmex credentials. A Collmex account is required. The free plan allows 50 tool calls per month; paid plans raise the limit.
Before you install
Two tools write to Collmex: creating a customer and creating an address-book entry. Each call creates a new record and never overwrites, so duplicates are possible if you do not check first; confirm before running them. The server returns business and personal data such as addresses, bank details (IBAN/BIC) and VAT ids, and it is a third-party host, so your Collmex data passes through it. Paid plans cost money and are billed through a Stripe checkout link; cancellation runs to the end of the…

Installation

In SourceWeft

  1. Open Collmex 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%2Fcollmex/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

Connect

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