FOCUS_NFE_TOKENAPI key for focus-nferequiredsecret

Names read from the package code (@codespar/mcp-focus-nfe@0.2.2). Descriptions and flags come from its manifest. Self-hosted, you hold the credentials. On the CodeSpar runtime the credential you connect is stored encrypted (AES-256-GCM, key derived per organization), and the runtime adds it to the provider call itself; the agent never receives it.

Compatibility

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

Through the CodeSpar runtime, codespar_discover finds this server's tools, and a tools/call runs with the credential connected in your project, a test key included.

Questions

Before you install.

How do I install the Focus NFe MCP server?

Run npx -y @codespar/mcp-focus-nfe@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. Prefer hosted? Add the CodeSpar endpoint with a test key and connect Focus NFe in your project; codespar_discover finds its tools.

What can my agent do with Focus NFe?

Focus NFe exposes 19 tools for fiscal. Your agent calls them directly; the full list is above.

How does Focus NFe authenticate, and how are credentials stored?

Focus NFe uses API Key. Self-hosted, you hold the credentials: the server reads them from its environment variables. On the CodeSpar runtime the credential you connect is stored encrypted for your organization, and the runtime adds it to each provider call, so the agent never handles it.

How does Focus NFe 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 Focus NFe open source? How do I report a bug?

Yes. Focus NFe is MIT-licensed and published on npm as @codespar/mcp-focus-nfe, 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.
