Supergateway MCP Bridge
MCPOfficialOpen SourceMIT83.6
by supercorp-ai • Blockchain & Crypto
Exposes MCP stdio-based servers over SSE, WebSocket, or Streamable HTTP to enable remote access, debugging, and client integration.
Example Use Cases
- 1
Expose a local stdio-only MCP server to web clients or remote tools via SSE or WebSocket for real-time interaction.
- 2
Integrate a remote SSE or Streamable HTTP MCP into local CLI workflows by bridging it to stdio.
- 3
Run MCP servers in containers or behind tunnels (ngrok/Docker) for debugging, inspection, or secure remote access.
Description
Supergateway converts MCP stdio servers into network-accessible transports (SSE, WebSocket, or Streamable HTTP) and can also connect remote SSE or Streamable HTTP MCPs to local stdio. It supports multiple modes (stdio→SSE/WS/StreamableHTTP, SSE→stdio, StreamableHTTP→stdio), header and OAuth2 auth, CORS, stateful session handling for Streamable HTTP, and Docker images for easy deployment. This makes it easy to debug, expose, or integrate stdio-only MCP servers with web clients, agent frameworks, and remote tooling like Claude, Cursor, or MCP Inspector.
Capabilities(14 total)
Tools (14)
read_file
Read the complete contents of a file as text. DEPRECATED: Use read_text_file instead.
path:string*tail:numberhead:number
read_text_file
Read the complete contents of a file from the file system as text. Handles various text encodings and provides detailed error messages if the file cannot be read. Use this tool when you need to examine the contents of a single file. Use the 'head' parameter to read only the first N lines of a file, or the 'tail' parameter to read only the last N lines of a file. Operates on the file as text regardless of extension. Only works within allowed directories.
path:string*tail:numberhead:number
read_media_file
Read an image or audio file. Returns the base64 encoded data and MIME type. Only works within allowed directories.
path:string*
read_multiple_files
Read the contents of multiple files simultaneously. This is more efficient than reading files one by one when you need to analyze or compare multiple files. Each file's content is returned with its path as a reference. Failed reads for individual files won't stop the entire operation. Only works within allowed directories.
paths:array*
write_file
Create a new file or completely overwrite an existing file with new content. Use with caution as it will overwrite existing files without warning. Handles text content with proper encoding. Only works within allowed directories.
path:string*content:string*
