MCP Integrations

Use Bizora's tax research capabilities directly in Claude, Cursor, Kiro, Codex, or any MCP-compatible client.

For setup in specific apps, see Claude, Kiro, or Codex. For the complete LLM-agent-facing contract, see Capabilities.

Endpoint

Use the Streamable HTTP endpoint for new clients:

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

Note: The legacy /sse endpoint remains available for older clients, but new setups must use /mcp.

Configuration

Prerequisites

Direct Remote MCP

Use this when your client supports remote MCP servers:

{
"mcpServers": {
"bizora-tax": {
"url": "https://mcp.api-bizora.ai/mcp"
}
}
}

OAuth-capable clients can discover the Bizora OAuth flow automatically. They do not need Auth0 client IDs, secrets, or callback URLs.

API-Key Header Configuration

Passing credentials and options via HTTP headers is the recommended approach for clients that support headers.

Why headers?

  1. Security: Query strings are often logged by web proxies and gateways. Putting your API key in the Authorization header keeps it secure.
  2. Cleanliness: It avoids cluttering connection URLs with complex options.

Here is the recommended configuration file block containing both authentication and configuration options as headers:

{
"mcpServers": {
"bizora-tax": {
"url": "https://mcp.api-bizora.ai/mcp",
"headers": {
"Authorization": "Bearer sk_live_YOUR_API_KEY",
"X-Tools": "auto"
}
}
}
}

Note: Never put your API key in query parameters.

Stdio-Only Clients

For clients that do not support remote transport directly, use mcp-remote:

{
"mcpServers": {
"bizora-tax": {
"command": "npx",
"args": [
"-y",
"mcp-remote@latest",
"https://mcp.api-bizora.ai/mcp",
"--transport",
"http-only"
]
}
}
}

How MCP Tools Work

Bizora exposes tools based on the tools parameter in the URL. Choose the right value based on your needs:

SelectorExposed toolBackend routeBest for
omittedtax-researchtax_research_fast_researchDefault focused tax research.
tax-researchtax-researchtax_research_fast_researchSame as default.
tax-fast-researchtax-fast-researchtax_research_fast_researchExplicit fast research.
tax-deep-researchtax-deep-researchtax_research_deep_researchExplicit deep research.
audit-researchaudit-researchaudit_researchExplicit audit research.
allall concrete toolsexplicit per-tool routeExpose every concrete public tool once.
autoa single generic toolautoLet Bizora choose the best route for every query across all supported domains.
auto,tax-fast-research,tax-deep-researcha single generic toolconstrained autoLet Bizora choose between explicitly selected routes.

Pass selectors in the URL when possible:

https://mcp.api-bizora.ai/mcp?tools=tax-fast-research
https://mcp.api-bizora.ai/mcp?tools=tax-deep-research
https://mcp.api-bizora.ai/mcp?tools=audit-research
https://mcp.api-bizora.ai/mcp?tools=all
https://mcp.api-bizora.ai/mcp?tools=auto
https://mcp.api-bizora.ai/mcp?tools=auto,tax-fast-research,tax-deep-research

Header alternatives are X-Tools and X-Include-Tools. URL parameters take precedence over headers. Do not combine tools=all with tools=auto; all exposes separate tools while auto exposes one auto-routing tool.

Citations and Response Formats

By default, Bizora MCP uses the minimal response format and returns a compact JSON payload with the final answer and source identifiers for citation mapping:

{
"answer": "Final answer text...",
"sources": [
{
"s3_file_path": "s3://...",
"node_id": "..."
}
]
}

Use a custom response format only when the client needs richer source metadata such as page labels, source origins, or source text:

https://mcp.api-bizora.ai/mcp?response_format=answer,sources.sourceOrigin,sources.page_label,sources.text

If requested source fields are absent, the AI should not invent citations. Retry with response_format=full when debugging the source payload.

Other Response Formats

You can request usage, progress steps, or the full structured response:

https://mcp.api-bizora.ai/mcp?response_format=full
https://mcp.api-bizora.ai/mcp?response_format=answer,usage
https://mcp.api-bizora.ai/mcp?response_format=answer,steps

Top-level fields are answer, usage, sources, and steps. Usage fields can be selected with usage.prompt_tokens, usage.completion_tokens, and usage.total_tokens.

Structured Response Skeleton

With response_format=full or X-Response-Format: full, MCP returns this structure:

{
"answer": "AI-generated answer text",
"usage": {
"prompt_tokens": 120,
"completion_tokens": 650,
"total_tokens": 770
},
"sources": [
{
"type": "source_message",
"content": [
{
"s3_file_path": "s3://...",
"node_id": "...",
"page_label": 1,
"sourceOrigin": "https://...",
"metadata": {
"sourceOrigin": "https://..."
},
"text": "Source excerpt..."
}
],
"request_id": "thread_..."
}
],
"steps": [
{
"type": "step_message",
"title": "Processing Query",
"description": "Research step description",
"request_id": "thread_..."
}
]
}

The fields inside each sources[].content[] item vary by source type. The example shows common fields; unavailable fields are omitted.

Source item fields can be selected with paths such as sources.sourceOrigin, sources.s3_file_path, sources.page_label, sources.metadata, sources.text, sources.tool, sources.citation_label, and sources.node_id. Default minimal includes only sources.s3_file_path and sources.node_id. If a selected field is missing, that field is omitted for that source item.

If you request both sources and nested source fields, sources wins and returns the complete source payload.

Zero Data Retention

Zero data retention is disabled by default for MCP requests. The default mode supports standard service operations such as usage analytics, abuse monitoring, reliability, billing, and security. To explicitly enable zero data retention, pass true:

https://mcp.api-bizora.ai/mcp?zdr=true

For clients that support custom headers:

{
"mcpServers": {
"bizora-tax": {
"url": "https://mcp.api-bizora.ai/mcp",
"headers": {
"Authorization": "Bearer sk_live_YOUR_API_KEY",
"X-Zero-Data-Retention": "true"
}
}
}
}

When zero data retention is enabled, prompt and response content is not retained for that connection. Some models or providers may be unavailable because they do not support zero data retention. You should handle abuse monitoring for zero data retention traffic because Bizora has limited content visibility for those requests.

Only true and false are valid values.

Capabilities Resource

The MCP server exposes the customer-facing capabilities guide as a standard MCP resource:

bizora://docs/capabilities

Clients that support MCP resources can read this resource to understand available tools, setup parameters, citation behavior, response formats, and known limitations.

Authentication Details

OAuth-capable clients discover Bizora's protected-resource metadata from:

https://mcp.api-bizora.ai/.well-known/oauth-protected-resource

For API-key based clients:

Authorization: Bearer sk_live_xxxxx

API keys must start with the sk_ prefix. Get your key from https://platform.bizora.ai.

Long-Running Requests

Tax research queries can take 60+ seconds. The server sends MCP progress notifications every 5 seconds when the client supplies a progressToken. Clients must support progress-based timeout reset for those notifications to prevent request timeouts.
