Destructive · High delete_check_account This tool permanently removes a bank account (check account) from the sevdesk accounting system.

POLICY

How to control Sevdesk

PolicyLayer is an MCP gateway — it sits between your AI agents and Sevdesk, and nothing reaches the server without passing your rules. These are the rules we recommend:

Block financial tools by default
{
  "book_voucher_payment": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Requires human approval."
      }
    ]
  }
}

Financial tools should be explicitly enabled per use case, not open by default.

Deny destructive operations
{
  "delete_check_account": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations
{
  "add_tag_to_object": {
    "limits": [
      {
        "counter": "add_tag_to_object_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "export_datev": {
    "limits": [
      {
        "counter": "export_datev_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

  1. Create a free account and register Sevdesk — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Sevdesk

Can an AI agent move money through the Sevdesk MCP server? +

Yes. The Sevdesk server exposes 1 financial tools including book_voucher_payment. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. PolicyLayer lets you block financial tools by default, require human approval, or set per-tool rate limits — enforced on every call.

Can an AI agent delete data through the Sevdesk MCP server? +

Yes. The Sevdesk server exposes 18 destructive tools including delete_check_account, delete_communication_way, delete_contact. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Sevdesk? +

The Sevdesk server has 41 write tools including add_tag_to_object, book_invoice_payment, change_order_status. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Sevdesk.

How many tools does the Sevdesk MCP server expose? +

103 tools across 4 categories: Destructive, Financial, Read, Write. 41 are read-only. 62 can modify, create, or delete data.

How do I enforce a policy on Sevdesk? +

Register the Sevdesk MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Sevdesk tool call.

Deterministic rules across all 103 Sevdesk tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
