- Block high-risk write tools while allowing read-only SaaS access
[ HOW TO CONNECT ]
Connect Composio to Bifrost in three steps
Install Bifrost
Start the gateway locally or deploy in your VPC.
npx -y @maximhq/bifrost
Add Composio in MCP Gateway
Open MCP Gateway in the Bifrost dashboard, click New MCP Server, and choose HTTP. Or register via the API below.
• Create or copy your Composio MCP server URL from the Composio dashboard.
• Pass your Composio API key via headers (commonly x-api-key). Confirm the header name in current Composio docs.
Point clients at Bifrost /mcp
Configure Claude Desktop, Cursor, or Claude Code to use your Bifrost endpoint with a virtual key instead of connecting directly to Composio.

}'[ WHY BIFROST ]
Run Composio through one governed gateway
Access control
Virtual keys, RBAC, and tool allowlists per team or agent.
Cost governance
Attribute MCP tool spend alongside LLM usage in one view.
Observability
Log every tool call with latency, server, and virtual key metadata.
Credential isolation
Upstream secrets stay in the gateway — not on every laptop.
[ FAQ ]
Common questions
What does the Composio MCP server do?
Composio exposes hundreds of saas toolkits, managed oauth to downstream apps, tool filtering per agent to MCP-compatible AI clients. Bifrost connects to it as an upstream MCP client and exposes approved tools through one governed /mcp endpoint.
How does Composio authenticate when used with Bifrost?
Composio uses Composio API key. Store credentials in Bifrost's environment or credential configuration so they stay at the gateway instead of being copied into every AI client.
Can Claude Desktop, Cursor, or Claude Code use Composio through Bifrost?
Yes. After registering Composio in Bifrost, point any HTTP MCP-compatible client at the Bifrost /mcp endpoint and authenticate with a virtual key. The client sees only the tools allowed for that key.
