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
- API key from https://platform.bizora.ai for API-key based clients.
- An MCP-compatible client.
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?
- Security: Query strings are often logged by web proxies and gateways. Putting your API key in the
Authorizationheader keeps it secure. - 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:
| Selector | Exposed tool | Backend route | Best for |
|---|---|---|---|
| omitted | tax-research | tax_research_fast_research | Default focused tax research. |
tax-research | tax-research | tax_research_fast_research | Same as default. |
tax-fast-research | tax-fast-research | tax_research_fast_research | Explicit fast research. |
tax-deep-research | tax-deep-research | tax_research_deep_research | Explicit deep research. |
audit-research | audit-research | audit_research | Explicit audit research. |
all | all concrete tools | explicit per-tool route | Expose every concrete public tool once. |
auto | a single generic tool | auto | Let Bizora choose the best route for every query across all supported domains. |
auto,tax-fast-research,tax-deep-research | a single generic tool | constrained auto | Let 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.
