Overview

AI-generated overview

Provides Brazilian financial market data from B3, including quotes, fundamentals, dividends, REITs, BDRs, crypto, FX, and macro indicators.

What you can do
A hosted, read-only MCP server for Brazilian market data (B3). According to its documentation it covers quotes, fundamentalist data, dividends, REITs (FIIs), BDRs, crypto, currency exchange, and macro indicators such as Selic and inflation. The README lists zero tools in its tool table, so the exact tool names and parameters are not shown here; usage examples include quoting PETR4, VALE3 and ITUB4, comparing dividend yields of HGLG11 and KNRI11, and asking for the latest Selic and IPCA.
When to use it
Useful when an assistant needs Brazilian market context: stock and REIT quotes, dividend comparisons, or macro indicators like Selic and inflation. It is aimed at users of MCP clients such as Claude, Cursor, VS Code, or any client supporting MCP over HTTP.
Requirements
A remote MCP over HTTP endpoint; no local runtime or package is needed. The README says it is hosted by the platform with no credentials, but requires a monthly subscription starting from a free tier and a magic-link login (no password). The server URL is given in the README.
Before you install
The README states the server is read-only and no tool changes source data. It is a paid subscription service (plans from a free tier). Data returned by the tools is sent to the LLM host you choose, which is described as a sub-processor outside the provider's control; the README recommends plans with training opt-out. The server itself is proprietary and hosted, while the public repository is MIT.

Installation

In SourceWeft

  1. Open Mercado Financeiro BR in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.mcp-dir%2Fmercado-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

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.

Takes no parameters.

Takes no parameters.

marketplace

Marketplace

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/<slug> link that opens without login.

authenticate

Authenticate

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: "<jwt>" } after the user pastes, or with no args to get the link.
