ObraAberta MCP

Read-only MCP server providing access to Brazilian public works data, including property details, builder directories, ratings, timelines, and nearby services. It enables agents to search for properties, compare records, and consult public transparency information without exposing personal data or allowing write operations.

Endpoint and access

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Ferramentas somente de leitura sobre dados públicos de obras e construtoras no Brasil (ObraAberta). Use `search_projects` e `find_projects_nearby` para descobrir empreendimentos, `get_project` para a ficha completa, `get_project_timeline`, `get_project_ratings` e `get_project_nearby_services` para detalhes, `list_builders`, `get_builder` e `get_builder_projects` para construtoras, `get_public_sources` para a procedência dos dados e `health` para disponibilidade. Nenhuma ferramenta escreve, publica ou altera dados. Não são expostos dados pessoais, cadastrais internos ou de autenticação. Ao citar dados, atribua à ObraAberta (obraaberta.com.br) e preserve a atribuição ODbL do OpenStreetMap nos serviços próximos. Não invente coordenadas, avaliações, nomes ou vínculos jurídicos: relate apenas o que os campos retornarem.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http obraaberta-mcp https://obraaberta.com.br/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add obraaberta-mcp --url https://obraaberta.com.br/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable obraaberta-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "obraaberta-mcp": {
      "url": "https://obraaberta.com.br/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "obraaberta-mcp": {
      "type": "streamableHttp",
      "url": "https://obraaberta.com.br/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start obraaberta-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "obraaberta-mcp": {
      "type": "http",
      "url": "https://obraaberta.com.br/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http obraaberta-mcp https://obraaberta.com.br/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "obraaberta-mcp": {
