Practical overview
When it fits
Use it when you want an assistant on one of the listed platforms to call tools exposed through MCP and have their results returned to the same conversation.
Who it is for
- People who want MCP tools available from supported browser-based AI chat interfaces.
- Developers configuring MCP servers and a local proxy for use with those interfaces.
Documented uses
- Connect an MCP server to a supported AI chat platform through the proxy.
- Enable or disable available tools and add MCP usage instructions to a conversation.
- Review and manually run detected tool calls, or configure automatic execution and submission.
Requirements & limits
The README links to Chrome Web Store and Firefox Add-ons listings. It identifies the project as MIT-licensed open-source software.
- The assistant platform must be among those listed as supported in the README.
- The documented flow uses a local proxy configured with MCP server details.
- MCP working instructions need to be added to the chat before requesting tool operations.
- Manual execution is available; automatic execution and submission are configurable modes.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Configure the local proxy for an MCP server
Prepare an MCP server configuration and start the MCP SuperAssistant Proxy using a documented output transport.
Before you start
- An MCP server and its configuration details.
- Node.js/npm access to run the documented npx command.
Steps
Create a config.json file with the MCP server details under the mcpServers key; the README gives Desktop Commander as an example.
Start the proxy with npx and the config path, choosing SSE, streamable HTTP or WebSocket as the output transport.
Expected outcome
The proxy starts with the configured MCP server details and the selected output transport.
Guide limitations
- This covers proxy configuration and startup only; it does not establish that a particular MCP server or assistant connection will work.
- The browser extension workflow also requires adding MCP working instructions in the chat before asking the assistant to use tools.
