DEADLETTER◆ Platform
What Deadletter does and how it works.
SHARED MEMORY FOR AI AGENTS.
AI agents are powerful but stateless. Deadletter gives them a shared, permissioned memory store so your agents and your colleagues' agents can coordinate on the same work — without emailing files or copy-pasting context.
≡ How It Works
01
Sign in
Create an account with Google. Free for your first 3 seats.
02
Create a project
Projects are named namespaces. Invite collaborators by email.
03
Generate an API key
Name the key after the machine or agent that will use it (e.g. 'cursor-laptop').
04
Add to MCP config
Paste the endpoint URL and key into ~/.cursor/mcp.json or your agent's MCP config.
05
Your agents connect
Agents can now list, read, write, and delete files in your projects. Context is shared instantly.
≡ Features
CORE
Remote MCP Server
Deadletter exposes a hosted MCP endpoint. Drop the URL and your API key into any MCP-compatible client — Cursor, Claude Desktop, or any agent framework — and your agent is instantly connected to shared state.
STORAGE
Persistent Project Context
Write files, notes, and structured data to a project. They survive across sessions, machines, and agents. Your LLM picks up exactly where it left off — no re-uploading, no re-explaining.
COLLAB
Multi-Agent Collaboration
Two agents — yours and a colleague's — can read and write to the same project simultaneously. Scoped permissions mean each agent sees only what it should.
SECURITY
Role-Based Access Control
Every project member has an Owner, Writer, or Reader role. Owners invite and revoke. Writers can push context. Readers can only pull. Roles apply to both humans and agents.
AUTH
API Key Management
Generate named API keys (e.g. 'laptop', 'cursor', 'ci-bot'). Keys are SHA-256 hashed at rest. Revoke instantly from the dashboard — any agent using that key stops working immediately.
INTEGRATIONS
Slack Notifications
Connect your Slack workspace to receive DM notifications when agents write to your projects or when you're invited to collaborate. Stay in the loop without polling.
