Overview

Bifrost provides 100% compatible endpoints for OpenAI, Anthropic, and Gemini APIs, making it seamless to integrate with any agent that uses these providers. By simply pointing your agent’s base URL to Bifrost, you unlock powerful features like:
  • Universal Model Access: Use any provider/model configured in Bifrost with any agent (e.g., use GPT-5 with Claude Code, or Claude Sonnet 4.5 with Codex CLI)
  • MCP Tools Integration: All Model Context Protocol tools configured in Bifrost become available to your agents
  • Built-in Observability: Monitor all agent interactions in real-time through Bifrost’s logging dashboard
  • Load Balancing: Automatically distribute requests across multiple providers and regions
  • Advanced Features: Governance, caching, failover, and more - all transparent to your agent

Configuration

Agent integrations work with your existing Bifrost configuration. Ensure you have:

​
Monitoring Agent Traffic

All agent interactions are automatically logged and can be monitored at http://localhost:8080/logs. You can filter by provider, model, or search through conversation content to track your agents’ performance. Agent Monitoring For complete monitoring capabilities, see Built-in Observability.

​
MCP Tools Integration

This feature is only available on v1.4.0-prerelease1 and above.
Bifrost exposes all configured MCP tools through a dedicated MCP server endpoint at /mcp. This allows external MCP clients (Claude Code, Cursor, and other MCP-compatible applications) to connect directly and access your tools.

​
Connect Claude Code to Bifrost MCP

Add Bifrost as an MCP server to Claude Code: 
claude mcp add --transport http bifrost http://localhost:8080/mcp
Using Virtual Key Authentication: If you have virtual key authentication enabled in Bifrost, connect using the JSON configuration format: 
claude mcp add-json bifrost '{"type":"http","url":"http://localhost:8080/mcp","headers":{"Authorization":"Bearer bf-virtual-key"}}'
Replace bf-virtual-key with your actual Bifrost virtual key. Claude Code will only have access to the specific MCP tools permitted by the virtual key’s configuration. To grant access to additional tools, verify or modify the virtual key’s MCP tool permissions in the Bifrost dashboard.

​
Supported Agents

You can connect any MCP-compatible client to Bifrost’s MCP server:
  • Claude Code - Add via claude mcp add command
  • Cursor IDE - Configure in cursor settings
  • Custom Applications - Any app implementing the MCP protocol

​
Tool Access Control

Control which tools each client can access using Virtual Keys:
  • Create a Virtual Key for each client/environment
  • Configure which MCP servers and tools the key can access
  • Bifrost automatically enforces these permissions
For complete setup instructions and tool filtering options, see MCP Gateway URL.
