# Claude

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:

```txt
https://mcp.api-bizora.ai/mcp
```

5. Save the connector and complete the browser sign-in when Claude asks for authorization.

6. 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](../overview.mdx) 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.
