MCP-Bridge exposes FastAPI endpoints that implement the OpenAI chat completions API specification, intercepting incoming requests and dynamically injecting available MCP tool definitions into the request payload before forwarding to downstream LLM inference servers. This allows any OpenAI-compatible client (Claude Desktop, LM Studio, Ollama, etc.) to transparently access MCP tools without modification. The middleware performs request transformation at the HTTP layer, mapping between OpenAI tool schemas and MCP tool schemas bidirectionally.
Unique: Implements transparent request/response transformation at the HTTP middleware layer using FastAPI, allowing unmodified OpenAI clients to access MCP tools by injecting tool schemas into the request before forwarding to inference servers, then extracting and routing tool calls back to MCP servers — no client-side changes required.
vs alternatives: Unlike direct MCP client libraries that require application code changes, MCP-Bridge works with any existing OpenAI API client as a drop-in proxy, making it faster to integrate into legacy systems than rewriting client implementations.
MCP-Bridge maintains a configurable pool of connections to multiple MCP servers, handling lifecycle management (connection establishment, health checks, reconnection on failure) through an MCP Client Manager component. The system discovers available tools from each connected MCP server, aggregates their tool definitions, and maintains a unified tool registry. Connection configuration is typically specified via environment variables or configuration files, allowing runtime addition/removal of MCP servers without code changes.
Unique: Implements a centralized MCP Client Manager that maintains persistent connections to multiple MCP servers, aggregates their tool definitions into a unified registry, and handles connection lifecycle (reconnection, health checks) transparently — enabling a single bridge instance to serve tools from many MCP sources.
vs alternatives: Compared to applications that connect directly to individual MCP servers, MCP-Bridge's multi-server aggregation allows a single proxy to unify tools from many sources, reducing client complexity and enabling centralized access control.
MCP-Bridge includes a structured release process with version tagging and release notes. The project uses semantic versioning and maintains a changelog documenting changes across releases. Release artifacts are published to package registries (PyPI, GitHub Releases, etc.), allowing users to install specific versions. The release process is automated via CI/CD pipelines that build, test, and publish releases.
Unique: Implements semantic versioning and automated release process with published artifacts to package registries, enabling users to install and manage specific versions of MCP-Bridge with clear changelog documentation.
vs alternatives: Compared to projects without formal release processes, MCP-Bridge's versioning and changelog provide clarity on changes and enable stable, reproducible deployments.
MCP-Bridge implements a tool mapping layer that converts MCP tool definitions (with MCP-specific schema format) into OpenAI function-calling schema format for injection into requests, and conversely translates OpenAI tool_call objects back into MCP-compatible tool invocation requests. This translation handles differences in schema representation, parameter validation rules, and response formatting between the two protocols, ensuring semantic equivalence despite format differences.
Unique: Implements bidirectional schema translation at the tool definition level, converting between MCP and OpenAI formats while preserving semantic meaning — allowing tools defined in MCP format to be transparently used by OpenAI API clients without requiring tool authors to maintain dual definitions.
vs alternatives: Unlike solutions that require tools to be defined separately for each protocol, MCP-Bridge's translation layer allows a single MCP tool definition to be used with OpenAI clients, reducing maintenance burden and ensuring consistency.
When an LLM generates tool_call objects in response to a chat completion request, MCP-Bridge intercepts these calls, identifies which MCP server should handle each tool, routes the invocation to the appropriate server, and collects results. The system maintains a mapping of tool names to their source MCP servers, enabling correct dispatch even when multiple servers provide tools with similar names. Tool execution is synchronous with request processing, and results are formatted back into OpenAI API response format.
Unique: Implements a tool dispatch layer that maps tool_call objects to their source MCP servers and executes them synchronously within the request/response cycle, enabling agentic workflows where LLM tool calls are immediately executed and results fed back for further reasoning.
vs alternatives: Unlike client-side tool execution where applications must implement their own routing logic, MCP-Bridge's centralized dispatch ensures consistent tool execution semantics and error handling across all clients.
MCP-Bridge supports both streaming and non-streaming chat completion responses. For streaming requests, it implements a Server-Sent Events (SSE) interface that forwards LLM token streams to clients while managing tool calls that may occur mid-stream. The system buffers tool calls, executes them when complete, and injects results back into the stream context. This enables real-time token delivery while maintaining tool-calling semantics.
Unique: Implements a streaming response handler that manages both token streaming and mid-stream tool calls, buffering tool invocations until complete, executing them, and injecting results back into the token stream — enabling real-time streaming while maintaining tool-calling semantics.
vs alternatives: Unlike simple streaming proxies that cannot handle tool calls, MCP-Bridge's SSE bridge manages the complexity of tool execution during streaming, allowing clients to receive real-time tokens while tools are being executed in the background.
MCP-Bridge includes an authentication middleware layer (implemented in auth.py) that validates API keys on incoming requests before processing. The system supports optional API key authentication — when enabled, all requests must include a valid API key in the Authorization header. Authentication is configurable via environment variables, allowing operators to enable/disable it without code changes. The middleware intercepts requests early in the FastAPI pipeline, rejecting unauthorized requests before they reach downstream processing.
Unique: Implements optional API key-based authentication as a FastAPI middleware layer that validates requests early in the pipeline, allowing operators to enable/disable authentication via environment variables without code changes — providing basic access control for deployments.
vs alternatives: While simpler than OAuth2 or JWT-based approaches, MCP-Bridge's API key authentication is sufficient for basic access control and can be deployed quickly without external authentication services.
MCP-Bridge includes a model sampling system that allows clients to specify which inference server or model to use for chat completions. The system forwards the model parameter from client requests to the downstream inference server, enabling selection between multiple models or inference backends. This allows a single bridge instance to route requests to different inference servers based on client preference, supporting scenarios where different models have different capabilities or performance characteristics.
Unique: Implements model sampling as a pass-through parameter that allows clients to specify which inference server or model to use, enabling a single bridge instance to route requests to different backends based on client preference without requiring bridge-level model management.
vs alternatives: Unlike load balancers that distribute requests blindly, MCP-Bridge's model sampling gives clients explicit control over which inference backend processes their request, enabling use cases like model selection and A/B testing.
