# mcp-sns-server MCP Server A Model Context Protocol server for interacting with DAOs on the Internet Computer This is a TypeScript-based MCP server that implements an interface to Service Nervous System (SNS) DAOs. It demonstrates core MCP concepts by providing tools to interact with decentralized autonomous organizations. [Demo](https://www.youtube.com/watch?v=Ljg0ee-8UFM) ## Setup add your seed phrase to env file ``` cp .env.example .env ``` ## Features ### Tools - `list_proposals` - List all proposals for a specific DAO - Takes DAO name as parameter - Returns list of proposals from the specified DAO - `list_votable_neurons` - List all votable neurons for a user in a DAO - Takes DAO name and principal ID as parameters - Returns neurons that can vote on proposals - `get_system_parameters` - List all configuration parameters for a DAO - Takes DAO name as parameter - Returns system parameters for the specified DAO - `wallet` - Get the user's wallet information - Returns the principal ID of the current wallet - `vote_proposal` - Vote on a proposal - Takes DAO name, principal ID, neuron ID, proposal ID, and vote preference - Allows voting yes, no, or unspecified on proposals - Registers vote with the DAO governance system ## Development Install dependencies: ```bash npm install ``` Build the server: ```bash npm run build ``` For development with auto-rebuild: ```bash npm run watch ``` ## Installation To use with Claude Desktop, add the server config: On MacOS: `~/Library/Application Support/Claude/claude_desktop_config.json` On Windows: `%APPDATA%/Claude/claude_desktop_config.json` ```json { "mcpServers": { "mcp-sns-server": { "command": "/path/to/mcp-sns-server/build/index.js" } } } ``` ### Debugging Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector), which is available as a package script: ```bash npm run inspector ``` The Inspector will provide a URL to access debugging tools in your browser.
