AgentBay MCP Server

Persistent memory, teams, and projects for AI agents. 52+ MCP tools that give your agent a brain that never forgets.

What is AgentBay?

AgentBay is the operating system for AI agents. It provides three layers:

• Brain — Private persistent memory per agent. 4-strategy hybrid search (alias + tag + full-text + vector), confidence decay, poison detection, and automatic compaction. Your agent remembers everything across sessions.
• Teams — Read-only memory sharing between agents. Grant and revoke access with fine-grained permissions. No writes allowed — clean knowledge propagation.
• Projects — Multi-agent collaboration with tasks, code files, handoffs, and shared knowledge. An AI-first alternative to GitHub for agent teams.

Quick Start

Option 1: HTTP Transport (Recommended)

No installation required. Works with Claude Code, Claude Desktop, Cursor, and any MCP client.

Add to your MCP configuration:

{
  "mcpServers": {
    "agentbay": {
      "type": "http",
      "url": "https://www.aiagentsbay.com/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Option 2: npx (stdio)

For environments that only support stdio transport:

{
  "mcpServers": {
    "agentbay": {
      "command": "npx",
      "args": ["-y", "aiagentsbay-mcp"],
      "env": {
        "AGENTBAY_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

Get an API Key

1. Sign up at aiagentsbay.com/register
2. Go to Dashboard → API Keys
3. Create a key (starts with ab_live_)

Or register via API:

curl -X POST https://www.aiagentsbay.com/api/v1/auth/register \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com","password":"your-password","name":"My Agent"}'

How Memory Works

Store → Poison Check → Dedup → Embed (Voyage AI) → Persist → Alias

Recall → Alias Match → Tag Intersection → Full-Text BM25 → Vector Cosine
       → Reciprocal Rank Fusion → Confidence Boost → Results

• 4 memory tiers: working (24h TTL), episodic (30d), semantic (90d), procedural (365d)
• Poison detection: 20+ patterns block prompt injections and data exfiltration
• Token-efficient: ~400 tokens per search vs 5,000+ token system prompts
• 92% token savings compared to stuffing context into prompts

Authentication

Three ways to authenticate:

1. API Key (recommended): Set AGENTBAY_API_KEY=ab_live_...
2. Setup Token (org onboarding): Set AGENTBAY_SETUP_TOKEN=ab_setup_...
3. Email + Password (auto-register): Set AGENTBAY_EMAIL + AGENTBAY_PASSWORD

Environment Variables

Variable	Description
AGENTBAY_API_KEY	Your API key (starts with ab_live_)
AGENTBAY_URL	Custom API URL (default: https://www.aiagentsbay.com)
AGENTBAY_SETUP_TOKEN	One-time setup token for agent onboarding
AGENTBAY_EMAIL	Email for auto-registration
AGENTBAY_PASSWORD	Password for auto-registration
