About MCP Bridge — Connect any API to any AI agent

MCP Bridge (by AppFactor) converts existing API schemas into Model Context Protocol (MCP) tools so AI agents can discover and invoke enterprise services without custom adapters or rewrites. It imports OpenAPI/GraphQL/WSDL/gRPC schemas, auto-generates typed tool definitions with parameter mappings and behavioural annotations, validates and maps inputs at runtime, handles authentication, and post-processes responses to reduce token usage. Designed for self-hosted, high-throughput deployments (implemented in Rust), MCP Bridge is intended for platform and enterprise teams who need secure, governed, and scalable access to internal and third-party APIs from LLM agents.

Key Features

Schema Import: Supports OpenAPI (JSON/YAML), GraphQL introspection, WSDL (SOAP) and gRPC (server reflection or .proto files) via URL, paste, or file upload to onboard APIs without code changes.
Auto-generated MCP Tools: Converts each API operation into a fully typed MCP tool with input/output schemas, parameter mappings, descriptive documentation, and behavioural annotations for accurate agent discovery and invocation.
Runtime Validation & Mapping: Validates inputs against generated schemas, maps parameters and authentication details, and forwards requests to backend services while preventing malformed calls.
Response Post-processing: Normalizes and trims API responses to reduce token consumption and produce agent-friendly outputs, improving cost-efficiency and relevance when used by LLMs.
Authentication & Governance: Centralizes handling of API authentication, rate limiting, and access controls so agents call services securely without shipping credentials or custom glue code.
High-performance Rust Core: Built in Rust for memory safety and high throughput to support production-scale deployments with minimal runtime dependencies.
Deployability & Marketplaces: Self-hosted in minutes with availability via AWS Marketplace and Microsoft Azure Marketplace, enabling enterprise deployment patterns and marketplace procurement.
Code Mode & Extensibility: Provides a code/configuration mode for advanced customizations and scaling, allowing platform teams to extend mappings, annotations, and post-processing logic.
