Compatibility

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

codespar_discover lists this server's tools, but a project with a test key cannot call them yet: the runtime has not recorded what this provider does in test mode, and refuses rather than guess.

Questions

Before you install.

How do I install the Zenvia MCP server?

Run npx -y @codespar/mcp-zenvia@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 Zenvia?

Zenvia exposes 18 tools for messaging. Your agent calls them directly; the full list is above.

How does Zenvia authenticate, and how are credentials stored?

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

How does Zenvia 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.

Is Zenvia open source? How do I report a bug?

Yes. Zenvia is MIT-licensed and published on npm as @codespar/mcp-zenvia, source on GitHub (link in the Details panel). Report issues on the package repository; security issues go to security@codespar.dev, and we respond within 24 hours.
