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
| Transport | Streamable HTTP (JSON-RPC 2.0 over POST) |
| Auth | OAuth 2.1 with PKCE (S256); bearer tokens; per-project authorization |
| Registration | Dynamic Client Registration (RFC 7591) — no static API key |
| Capabilities | 8 tools · 0 resources · 0 prompts |
| Registry name | one.zerno/zerno-lite |
| Manifest | https://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).
Tools (8)
| Tool | Does | Writes? |
|---|---|---|
zerno_get_project_brief | Project orientation: focus, next action, do-not-do, memory index | no |
zerno_get_agent_context | Compiled project memory + recent events for an agent run | no |
zerno_list_tasks | Filtered backlog listing | no |
zerno_get_task | Full detail for one task | no |
zerno_update_task | Patch task fields/status (ICE recomputed) | mutates |
zerno_submit_task_triage | Submit triage proposals (pending human approval) | creates proposals |
zerno_create_agent_intake_task | File a review task from an agent report | creates a task |
zerno_capture_session_event | Append a session summary to project memory | creates memory event |
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.
