Connect Claude to Bizora with a remote custom connector. This uses Bizora's Streamable HTTP MCP endpoint and Claude's OAuth flow.

Setup​

This setup uses Claude's remote custom connector flow in Claude.ai and Claude Desktop where Customize > Connectors is available.

  1. Open Claude and go to Settings > Customize.
  2. Choose Add custom connector.
  3. Name the connector Bizora Tax.
  4. Use this connector URL:
https://mcp.api-bizora.ai/mcp
  1. Save the connector and complete the browser sign-in when Claude asks for authorization.

  1. Start a new Claude chat and ask a tax research question.

What Claude Receives​

  • Tool access through Bizora MCP at https://mcp.api-bizora.ai/mcp.
  • OAuth discovery through https://mcp.api-bizora.ai/.well-known/oauth-protected-resource.
  • Compact source identifiers for citations in the default minimal response: sources.s3_file_path and sources.node_id.
  • The default tax-research tool, backed by tax_research_fast_research.

For tool selectors, response formats, ZDR, and long-running request behavior, use the MCP Server page as the source of truth.

Troubleshooting​

Do not add the Bizora remote MCP URL to claude_desktop_config.json; that local config file is for local stdio-style MCP servers.

If Claude Desktop shows Some MCP servers could not be loaded and mentions claude_desktop_config.json, the local Desktop config is invalid JSON or is using a config shape Claude cannot load.

For this guide, use the remote custom connector flow above. It avoids local JSON setup and uses the current /mcp endpoint directly.
