Limitations

  • The package manifest does not declare 3 of the 3 variables the code reads.
  • The package manifest declares CIELO_API_KEY, which the code does not read.
  • Hosted calls with a test key are not available: connecting this provider needs credentials it issues to an operator.

Compatibility

MCP is a protocol. Any client that speaks it can mount this server.

codespar_discover lists this server's tools, but connecting it needs credentials the provider issues to an operator (a certificate, signed keys or paired headers), which a test key cannot produce.

Run npx -y @codespar/mcp-cielo@0.2.2 and add the config block above to your MCP client: Claude Code, Cursor, Claude Desktop, VS Code, or any MCP-compatible client. No build step, no SDK required.

What can my agent do with Cielo Acquirer?

Cielo Acquirer exposes 22 tools for payments. Your agent calls them directly; the full list is above.

How does Cielo Acquirer authenticate, and how are credentials stored?

Cielo Acquirer uses API Key. Self-hosted, you hold the credentials: the server reads them from its environment variables.

How does Cielo Acquirer handle upstream API changes?

Every server is versioned independently on npm. The command on this page pins 0.2.2, the version whose tools are listed here; your agent keeps running it until you change the version.
