ZERNO Lite — MCP Server

Official metadata for the ZERNO Lite Model Context Protocol (MCP) server.

ZERNO Lite is a remote MCP server that connects AI agents to ZERNO project context — project briefs, task and agent context, and structured intake workflows — over a secure, OAuth-authorized endpoint. It's built for coding agents, product agents, and automation workflows that need to understand a project before acting, without unrestricted backend access.

This repository is the public "front door" for the hosted server: metadata, server.json, and the tool catalog for MCP directories. It does not contain the backend source — the server runs as a hosted service at the endpoint below.

Endpoint

https://zerno.one/mcp
TransportStreamable HTTP (JSON-RPC 2.0 over POST)
AuthOAuth 2.1 with PKCE (S256); bearer tokens; per-project authorization
RegistrationDynamic Client Registration (RFC 7591) — no static API key
Capabilities8 tools · 0 resources · 0 prompts
Registry nameone.zerno/zerno-lite
Manifesthttps://zerno.one/.well-known/mcp

Quickstart

Add a remote connector named zerno with URL https://zerno.one/mcp, then complete the OAuth consent in the browser.

  • Claude Code / Claude Desktop: Settings → Connectors → add custom connector (name zerno, URL above).
  • Codex CLI: codex mcp add zerno --url https://zerno.one/mcp
  • Cursor: Settings → MCP → Add server → URL https://zerno.one/mcp

For user-scoped tokens, tell the agent which project with a project_slug (e.g. zerno-one).

Full machine-readable schemas: tools-list.json. No tool deletes data or calls third-party services. tools/list is scope-filtered — a read-only token sees only the four read tools.

Security & privacy

Every call requires OAuth; nothing is exposed unauthenticated. Bearer tokens are hashed at rest, no secrets are returned in tool output, and every call is audit-logged. Access is tied to the user's authorized ZERNO workspace/project.

Limitations

Requires a ZERNO account and an authorized project. Remote/hosted only (no stdio or packaged distribution). Tools only — no MCP resources or prompts.
