Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00059 | $0.00555 |
| Opus 5 | $0.00030 | $0.00278 |
| Sonnet 5 | $0.00012 | $0.00111 |
| Haiku 4.5 | $0.00006 | $0.00056 |
Grade A, and why
business-account-opening scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Business Account Opening
Open a Vivid Business account using the vivid-mcp remote MCP server.
Integration
- Server:
https://api.prime.vivid.money/mcp(remote, streamable HTTP) - Tool:
build_onboarding_link— accepts legal entity data, returns an onboarding URL - Auth: none required — the endpoint is publicly accessible
- Install: nothing to install — the MCP server is hosted by Vivid; the client connects via the
.mcp.jsonconfig in this repository
Trigger
User wants to open a business account or start business onboarding.
Flow
- Ask for legal entity type (GmbH, UG, freelancer, etc.) if not provided.
- Ask for country if not provided. Default: Germany.
- Call MCP to get required fields and accepted document types.
- If the user uploads a document, extract the fields locally in the client — the document itself is never sent to the MCP server. Summarize what was extracted; do not echo raw document contents.
- Show the user a summary of all collected data and ask for explicit confirmation before proceeding.
- Call
build_onboarding_linkwith the confirmed data. The server returns an onboarding URL. - Present the URL to the user.
Data handling
- Documents stay local. Uploaded files are parsed by the AI client. Only structured fields (company name, address, etc.) are sent to the MCP server.
- No PII stored by the skill. The skill does not persist any data. The MCP server creates an onboarding session;
- No credentials in chat. Never ask for or accept passwords, API keys, or bank account numbers.
Rules
- Always confirm collected data with the user before calling
build_onboarding_link. - Never call the tool autonomously — require explicit user approval.
- Treat uploaded documents as sensitive — summarize only, don't echo contents.
- On error: ask for missing fields or suggest a different document.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
