Mercado Livre (Latin America's largest marketplace) via the official API, seller profile and reputat
Scored across 20 tools
The Mercado Livre tools are mostly distinct (get, list, search, authenticate, etc.), but three tools stand out: `authenticate`, `connect`, and `marketplace` overlap in purpose (all deal with authentication and connections). The `marketplace` tool is a meta-tool that runs other MCPs, which could be confused with the server's own tools. However, the Mercado Livre domain tools are clearly separated by resource (category, item, order, question, shipment, user).
The Mercado Livre tools follow a consistent pattern `mercadolivre_<verb>_<resource>` (e.g., `mercadolivre_get_items`, `mercadolivre_list_orders`), which is good. However, the non-Mercado tools (`authenticate`, `connect`, `marketplace`, `report_bug`, `show_version`, `toolkit_info`) use a different, generic style, mixing lowercase single words and snake_case. This mixed convention breaks the overall naming consistency.
With 20 tools, the server is at the high end of the 'reasonable' range. The Mercado Livre specific tools (14) cover a well-scoped domain, but the extra 6 tools for MCP platform management (authenticate, connect, marketplace, report_bug, show_version, toolkit_info) feel like a separate concern appended to the server, making the count slightly bloated for a single-purpose server.
The Mercado Livre tools provide solid read coverage (get, list, search, visits) but lack write operations: there's no create, update, or delete for items, orders, questions, or shipments. For a 'Vendedor' (seller) server, this is a significant gap—sellers would expect to at least update items or answer questions. The absence of any mutation tools makes the surface incomplete for typical seller workflows.
MCP.AI for IDE agents (Cursor, etc.): log in in the browser, copy the access token. Best: add it to this server's config as a header Authorization: Bearer <token> for a permanent, non-expiring connection. Or paste it here for a session-only login: call with { token: "" } after the user pastes, or with no args to get the link.
Inputs: token.
Returns connection status and URLs. When all providers are connected, returns authenticated:true and empty pending[]. When credentials are missing, returns connect_url for the toolkit and per-install URLs.
Inputs: no named parameters.
The official mcp.ai marketplace — the in-platform catalog of every MCP/tool, AND the way to run them. Covers capability requests like "find an MCP that does X", "consulta um CPF", "is there a tool for Y". Core flow: action=search discovers MCPs by intent → describe returns one MCP's full profile (every tool with its id + params, pricing, auth) so you pick the right tool_id → invoke RUNS that tool. KEY: invoke works even when the MCP is NOT installed — it runs the tool pontualmente (one-off), without adding the MCP to the toolkit and without bloating the tool list. If the MCP needs a credential/login, invoke returns a connect link; if it is paid and the wallet is empty, invoke returns a checkout/top-up link (the user opens it, then you retry). Use install only to make an MCP PERMANENT in the active toolkit (its tools then show up natively in future sessions); prefer invoke for a single/occasional use. list_tools lists what is callable right now. subscribe/cancel handle per-MCP billing; report_bug sends feedback; request_mcp asks us to build a NEW MCP when nothing fits. Search/describe flag installed_in_toolkit vs installed_in_workspace. Writes (install/uninstall/subscribe/cancel and the one-off install behind invoke) require workspace owner/admin. It also carries the mcp.ai PROMPT LIBRARY, which is about ready-made prompt TEXT rather than MCPs: search_prompts finds one, get_prompt returns its full text with {{variables}} filled, and publish_prompt saves a prompt and returns a shareable mcp.ai/p/ link that opens without login.
