Colloid

About

Colloid functions as an API gateway specifically designed for the Model Context Protocol (MCP), centralizing the management, security, and orchestration of diverse MCP servers. It sits between LLM applications and various MCP servers (such as GitHub, Slack, or custom tools), seamlessly distributing requests and enabling combined tool functionalities with namespacing. The gateway enhances resilience, observability, and security through features like authentication, rate limiting, and tracing, providing a robust and streamlined interface for integrating LLM-powered applications with external tools and services.

Key Features

• Comprehensive Security (API Keys, RBAC, rate limiting, audit logging, SSRF protection)
• Resilience (Circuit breakers, retries, timeouts, idempotency)
• Observability (OpenTelemetry tracing, structured logging, health checks)
• Workflow automation by chaining multiple tool calls
• Tool Aggregation with namespacing
• 0 GitHub stars

Use Cases

• Securing LLM application interactions with external tools through robust authentication and rate limiting.
• Centralizing access and management for multiple MCP servers across an organization.
• Building automated workflows by orchestrating tool calls from diverse MCP services.
