# JustIdea Prestashop DEMO — agent protocols

> Everything needed to work with the MCP servers, the A2A endpoint, the published skills and how to get a token at JustIdea Prestashop DEMO. Read-only throughout.

Scoped to one section. For the catalogue itself see [llms.txt](https://prestashop.justidea.dev/llms.txt); for the full integration surface see [developers/llms.txt](https://prestashop.justidea.dev/developers/llms.txt).

## Start here

- [Developer portal](https://prestashop.justidea.dev/agent/docs): every endpoint, format, error code and code sample on one page.
- [AGENTS.md](https://prestashop.justidea.dev/AGENTS.md): conventions a coding agent should follow when writing an integration.
- [auth.md](https://prestashop.justidea.dev/auth.md): what needs a credential (almost nothing) and how to issue yourself one.

## Agent protocols

- [MCP — storefront](https://prestashop.justidea.dev/agent/mcp): search_products, get_product, list_categories, check_availability, get_shipping_options, get_policies, create_checkout_link.
- [MCP — documentation](https://prestashop.justidea.dev/agent/docs-mcp): search and read these guides.
- [MCP manifest](https://prestashop.justidea.dev/.well-known/mcp) · [server card](https://prestashop.justidea.dev/.well-known/mcp/server-card.json)
- [A2A agent card](https://prestashop.justidea.dev/.well-known/agent-card.json): ask in a sentence at https://prestashop.justidea.dev/agent/a2a.
- [Agent skills](https://prestashop.justidea.dev/.well-known/agent-skills/index.json)

## Registration and limits

- Reading needs no account, no key and no signup.
- [Issue a token](https://prestashop.justidea.dev/v1/register) for MCP `tools/call`; send `Idempotency-Key` and a retry returns the original one.
- Rate limits are reported in `RateLimit-*` headers; a 429 carries `Retry-After`.
- Discovery documents are never throttled.
