Authenticated Mcp Agent

mikerawsonnz/gosce-agents

This is a JWT-authenticated gateway to Google Vertex AI's Gemini models via LangChain. You register and log in through bcrypt-secured endpoints, get a JWT token, then use it to hit a completion endpoint that routes your prompt through LangChain's orchestration layer before hitting Gemini. It's one of several agents in the GOSCE portfolio, all built by an automated pipeline that scans GitHub dependencies and spins up monetizable combinations as MCP servers. The auth layer makes it suitable when you need metered access or user-scoped LLM calls rather than direct API keys. Part of the getvda.ai hosted agent ecosystem with x402 micropayment support.

Install

From registry metadata
$ npx add-mcp https://bcrypt-langchain-core-mcp-25b8f1.getvda.ai/mcp --name authenticated-mcp-agent

Run in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.

Review the command, arguments and environment values before installing. MCP servers run with your local permissions.

Readme

GOSCE Agents

A portfolio of production remote MCP + A2A agents running on getvda.ai, discovered + quality-assured by the GOSCE Portfolio Router. Each agent is capability-scoped, speaks open A2A + MCP, and is metered with Nevermined x402 micropayments (discovery is free).

Generated by GOSCE (GitHub Open-Source Combination Engine) — an automated pipeline that mines the OSS dependency graph for monetizable package combinations and deploys each as a verified agent.
