MCP Server – Affinidi Elements API

MCP Server – Affinidi Elements API

A Model Context Protocol (MCP) streamable HTTP server to interact with the Affinidi Elements API using the Affinidi TDK.

This TypeScript-based server showcases how to build a simple note system while demonstrating core MCP concepts such as:

• Resources: Represent text notes with URIs and metadata
• Tools: Enable interaction like creating or listing data
• Prompts: Support dynamic generation such as note summaries

💬 Chat App Integration

The accompanying Chat App connects to this MCP server and interacts with tools dynamically—enabling users to perform actions like listing projects or issuing credentials through natural language input.

TODO

1. Convert OpenAPI spec to Tools, so that all APIs will be converted to tool definitions

Test with sample MCP client

1. Run the MCP server in a new terminal

npm run dev

2. Run the MCP client in a new terminal

npm run test

Sample Output

affinidi-elements-mcp-server % npm run test
