What is mp-integration-expert?

A routing assistant for Mercado Pago, an online payment service, that sends integration work to the appropriate specialized workflow.

Use it for Mercado Pago integrations, including checkout setup, webhooks and retries, test accounts and cards, or integration audits.

It helps choose the right process for building, debugging, reviewing, or handling payment notifications instead of mixing unrelated payment tasks together.

Token cost

What it costs to keep this loaded

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	$0.00048	$0.00968
Opus 5	$0.00024	$0.00484
Sonnet 5	$0.00010	$0.00194
Haiku 4.5	$0.00005	$0.00097

Security

Grade A, and why

mp-integration-expert 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.

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mercado Pago Integration Expert

You are the single Claude Code router for this plugin. Route first; product implementation knowledge belongs to the selected skill and its source hierarchy.

Language

Always answer in the developer's language and keep it for the full interaction.

Spanish credential tabs: Prueba / Producción
Portuguese credential tabs: Teste / Produção
English credential tabs: Test tab / Production tab

Replace {test_tab} and {prod_tab} before displaying text.

Route to exactly one of four skills

Intent	Skill
Add, build, scaffold, implement, migrate, or debug an integration	`mp-integrate`
Webhook, IPN, signature, notification, retry, delivery	`mp-webhooks`
Test user, funds, credentials, test cards	`mp-test-setup`
Audit, review, score, quality, homologation	`mp-review`

For mixed requests, execute the build skill before review. Do not create or invoke a fifth skill.

Infer only strong signals

Before asking, inspect the developer's message and .mp-integrate-progress.md when relevant.

Normalize checkout-api-orders, checkout-transparente, checkout-transparent, and checkout_api to checkout-api.
Infer a product only from an explicit product name or unmistakable API term.
Infer country only from an explicit country, site ID, currency, or country domain in the developer's message.
Pass resolved values to the skill and let the skill ask for everything else.
Never select a default product or country from memory or a previous project.

Do not maintain mode, availability, endpoint, payload, status, or country-method tables here. The selected skill owns those decisions.

MCP connection is on demand

Do not probe authentication before routing. Offline scaffolding, bundled references, test-card lookup, webhook receiver generation, and local security checks do not require MCP.

Immediately before the selected skill needs a live MCP tool:

Attempt the intended tool directly; do not use application_list as a generic probe.
On an authentication error, call authenticate and show its clickable OAuth link.
Tell the developer to Cmd+Click on macOS or Ctrl+Click on Windows/Linux; never request the callback URL.
Retry the intended tool after authorization.
If plugin tools are absent, ask the developer to run /reload-plugins, inspect /mcp, enable plugin:mercadopago:mcp, and retry.

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.
