MCP Bridge auto-generates Model Context Protocol tool definitions from any REST, GraphQL, SOAP or gRPC API and runs as a self-hosted Docker service.
- for
- Platform engineers, AI engineers, and enterprises building AI agents that need API access.
- pricing
- freemium · free trial
Key features
- Schema-driven tool generation — Imports OpenAPI, GraphQL, WSDL or .proto schemas and creates fully typed MCP tools automatically.
- Self-hosted deployment — Runs in a Docker container on any orchestrator (AWS ECS, Azure Container Apps, etc.) with zero SaaS dependencies.
- Code Mode token optimization — Reduces context window usage by ~98% using three meta-tools instead of hundreds of individual definitions.
- Enterprise auth & rate limiting — Supports Bearer, Basic, API Key, OAuth2, AWS Cognito SRP and configurable token bucket limits.
- Observability dashboard — Provides latency, throughput, token usage and error metrics via OpenTelemetry integration.
- Semantic tool search — Hybrid full-text, fuzzy and optional vector similarity search for quick tool discovery.
Use cases
- Expose internal micro-services to LLM agents without writing custom adapters.
- Build AI agents that call enterprise APIs with built-in auth, rate limiting and response post-processing.
- Replace hundreds of hand-crafted tool definitions with three meta-tools to cut token costs.

MCP Bridge by Appfactor FAQ
How do I generate tools for an API?+
Provide a schema URL, paste the content, or upload the file; MCP Bridge parses OpenAPI, GraphQL, WSDL or gRPC and creates tools automatically.
Do I need to run a separate gateway for my APIs?+
No, MCP Bridge translates APIs into MCP tool definitions rather than routing raw HTTP traffic.
Can I run MCP Bridge on my own infrastructure?+
Yes, it is delivered as a Docker container that can be deployed on any orchestrator such as AWS ECS or Azure Container Apps.
What is Code Mode and how does it help?+
Code Mode replaces hundreds of tool definitions with three meta-tools, reducing LLM context usage by about 98% while preserving functionality.
What authentication methods are supported?+
Bearer, Basic, API Key, OAuth2, AWS Cognito SRP and OIDC for the UI via providers like Entra ID, Keycloak, Auth0 or Okta.
