Tools & prompts

Every tool the BeeL. MCP server exposes, the guided workflow prompts, and the inline invoice PDF viewer.


Through the BeeL. MCP server your assistant can do everything the BeeL. API offers — issue and manage invoices, customers, products, NIFs, payments and more — plus a few helper tools and guided prompts that keep fiscal steps in the right order. The tool set covers the whole API and grows with it.

Tools are named beel_<action> and grouped by resource. Each needs specific scopes; the assistant can only use a tool if the scopes you approved on the consent screen cover it.

Helper tools

A few tools help the assistant orient itself before it acts:

ToolDescription
beel_get_setup_statusOne-call checklist of every NIF's readiness with a recommended next action — the fastest way to see what's missing.
beel_docs_searchSearch these docs from inside the client.
beel_docs_getRead a documentation page in full.
beel_docs_listList the available documentation pages.

Guided prompts

Prompts are templates you invoke like a command; they seed the conversation with the correct order of operations so the assistant doesn't skip a fiscal step.

PromptWhat it does
issue-invoiceIssue a compliant invoice: F1 vs F2, validate the NIF, set regime keys, clear the VeriFactu gates.
fix-invoiceFix an issued invoice the right way: void (anulación) vs corrective (rectificativa R1–R5).
onboard-nifGet a NIF ready to issue Live end to end: readiness → default series → VeriFactu → payments → first Test invoice.
setup-representationSet up the AEAT fiscal representation (apoderamiento) a NIF needs for VeriFactu — resolves the NIF_REPRESENTATION_REQUIRED blocker.
invite-memberInvite a collaborator (gestoría) or teammate and grant the right role, account-wide or per-NIF.
connect-paymentsConnect Stripe to a NIF or account-wide, and verify it is active.
upgrade-integrationBring an existing BeeL. API integration up to current best practices.

Inline invoice PDF

When the assistant fetches an invoice PDF, the BeeL. MCP server returns it as an MCP App: a client that supports MCP UI (such as Claude) renders the invoice inline in the chat as an embedded viewer, instead of a bare download link — so you review the document without leaving the conversation.
