Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Read TOConline customers, suppliers, products, sales documents, receipts and purchases.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

It passed 3 of 3 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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed –, and the latest version (1.6.4) reached the registry today.
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 in developer mode.

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 TOConline credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/toconline/
An Empresário opens Empresa → Configurações → Dados API, identifies the integrator, and receives a temporary access link containing the company's Client ID, Client secret, OAuth URL and API URL. Enter these on the connector's login page. Use the matching numeric API and OAuth shard URLs supplied by TOConline.
The registered redirect URI defaults to https://oauth.pstmn.io/v1/callback. If changed in TOConline, enter its exact HTTPS value. The connector captures the authorization code directly from the vendor response without visiting that callback. A customer, product or supplier record with a company relationship is required to identify your company.
The 20 product tools read customers, suppliers, products, sales documents, receipts, purchases and reference data. They do not change accounting records.
