Limits, troubleshooting and FAQ
What the connector does NOT do (by design)
Section titled “What the connector does NOT do (by design)”The connector is read-only. Actions are yours to take, in the B2Brouter web app or via the API, as always. This isn't a temporary limitation: it's the security design (see Why it's read-only).
| Doesn't do | What to do instead |
|---|---|
| Create, modify, send or delete invoices and documents | B2Brouter panel or REST API |
| Chase payments, send reminders | Panel (the assistant explains how) |
| Actions on the subscription or account configuration | Panel |
| Automatically tell you if your account is "ready" for an authority (Verifactu, DGFiP, KSeF...) | Check the authority's documentation and review the configuration in the panel |
| Search the directory for companies by approximate name | Search by exact tax ID (NIF, SIRET, Partita IVA, NIP, VAT number...); search by name is under consideration |
| An aggregated summary of all your accounts at once | Ask account by account, or let the assistant go through them (slow with large portfolios) |
Usage limits
Section titled “Usage limits”| Limit | Detail |
|---|---|
| Directory | 50 searches per day and user; other features have no specific limit |
| Listings | 25 results per page by default, up to 100; the assistant paginates on its own |
| Financial summary | One currency per summary; multi-currency accounts, separately |
| Plan | Active paid account to connect; Professional or higher for invoices, reports and finances |
If something isn't working
Section titled “If something isn't working”| Symptom | Likely cause | Solution |
|---|---|---|
| "An account with an active subscription is required" | Your user doesn't have access to any account with an active paid subscription | Activate or renew a subscription, or ask to be added to a paid account |
| Authorization doesn't finish / doesn't return to the assistant | Pop-up blocking or session expired mid-flow | Allow the B2Brouter window, sign in and repeat the connection |
| The assistant doesn't offer B2Brouter | The platform doesn't have the connector in its directory | Add it manually by URL (https://app.b2brouter.net/mcp) following the steps for each client |
| The assistant doesn't show any B2Brouter tools | The connector is turned off in this conversation, authorization wasn't completed, or you've blocked the functions in the assistant's settings | Turn on the connector in the conversation, review its permissions in the assistant's settings and, if needed, reconnect it |
| The assistant asks you to sign in again, or says "A valid OAuth bearer token is required" | The authorization has expired or was revoked from Authorized applications | Disconnect the connector in the assistant and connect it again |
| "Not found or not authorized" when querying an invoice or report | The identifier doesn't exist or you don't have permission to see it (the message is intentionally the same) | Check the identifier and that your user has access to that section of the account; if it's a client account, its plan might not include the connector |
| "Rate limit reached" on the directory | You've exceeded the 50 daily searches | Wait until the next day or check the directory from the panel |
If the problem persists, contact B2Brouter support through the usual channel.
Frequently asked questions
Section titled “Frequently asked questions”Do I need an API key?
No. The connection is made with your B2Brouter user, with an authorization you approve in the browser.
Do I need to know how to code?
No. Connecting it is three steps in your chat assistant, and from then on you just talk. The technical detail in this guide is optional.
Can everyone in the company use it?
Each person connects their own user and has their own scope. Access and permissions are never shared.
Is there a limit on accounts?
No: the assistant sees every account where you're a member.
Are the financial summary figures reliable?
They come from the same engine as the panel's dashboard: they're the same figures. For critical tax or accounting decisions, always verify against the primary source.
Can the assistant make up answers about regulations?
The data in your account always comes from B2Brouter. For questions about regulations or how the product works, the connector points the assistant to the official documentation; if the assistant can't read it, it will answer from its general knowledge, which can be wrong. Before a decision with tax consequences, confirm with your advisor or with support.
Why can't it fix the invoice if it can already see what's wrong?
A deliberate security decision for this first version: everything is read-only. Write capabilities will be studied later, with their own risk analysis.
Why does it tell me "Not found or not authorized" if the invoice exists?
Because your user doesn't have access to it (section, account or plan). The message doesn't distinguish "doesn't exist" from "not authorized", for security.
Can I use it from my code editor?
Yes. Any MCP-compatible coding agent (Claude Code, Cursor, VS Code...) connects with the same URL and the same authorization flow. See the steps for each client.
What languages does it work in?
Ask in whatever language you like: the assistant translates. B2Brouter's official documentation is published in Catalan, English, Spanish and French.
