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
- Sign up at aiagentsbay.com/register
- Go to Dashboard → API Keys
- 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:
- API Key (recommended): Set
AGENTBAY_API_KEY=ab_live_... - Setup Token (org onboarding): Set
AGENTBAY_SETUP_TOKEN=ab_setup_... - Email + Password (auto-register): Set
AGENTBAY_EMAIL+AGENTBAY_PASSWORD
Environment Variables
| Variable | Description |
