MCP Servers

Integrate any MCP server in 2LY

2LY integrates any Model Context Protocol (MCP) server available on the market—from official provider implementations to community packages. Configure once in the Tool Registry, use across all agents.

What are MCP Servers?

MCP is an open standard protocol developed by Anthropic for AI tool interfaces. It provides:

  • Standardized APIs: Consistent interface patterns across tools
  • Type Safety: Well-defined schemas for inputs and outputs
  • Self-Documentation: Automatic capabilities and parameters discovery
  • Error Handling: Standardized error reporting

Reference: Model Context Protocol

Tool Registry

All configured MCP servers are stored in 2LY's Tool Registry—a centralized catalog of available tools:

  • Configure MCP servers once
  • Access from any agent
  • Test tools before deployment

The Tool Registry ensures consistent tool access across your entire agent ecosystem.

Supported Server Types

2LY supports all MCP server communication patterns:

STDIO Servers

Standard process communication via stdin/stdout:

{
  "type": "stdio",
  "command": "npx",
  "args": ["@modelcontextprotocol/server-filesystem", "/data"],
  "env": {
    "PATH_ROOT": "/data"
  }
}

Common use: Node.js packages, Python scripts, local binaries

HTTP Servers

RESTful MCP implementations:

{
  "type": "http",
  "url": "https://api.example.com/mcp",
  "headers": {
    "Authorization": "Bearer ${API_TOKEN}"
  }
}

Common use: Cloud services, remote APIs, enterprise systems

WebSocket Servers

Real-time bidirectional communication:

{
  "type": "websocket",
  "url": "wss://api.example.com/mcp",
  "protocols": ["mcp-v1"]
}

Common use: Streaming data, live updates, persistent connections

Adding MCP Servers

2LY provides two ways to add MCP servers to your Tool Registry:

1. Browse Official Catalog

Access the official Anthropic MCP server catalog directly from 2LY:

  • Curated Registry: Pre-validated, community-maintained servers
  • One-Click Add: Deploy catalog servers with minimal configuration
  • Quality Assurance: Servers validated by Anthropic and community
  • Automatic Updates: Server definitions sync from official registry

Examples: Filesystem, GitHub, PostgreSQL, Slack, Brave Search

2. Add Manually

Configure any custom or community MCP server:

  • Simplified UI Workflow: Step-by-step configuration wizard
  • Connection Testing: Validate server connectivity before saving
  • Environment Variables: Secure credential management
  • Custom Sources: Private servers, internal tools, experimental packages

Configuration Workflow

  1. Select Source: Choose from Anthropic catalog or manual entry
  2. Configure Connection: Set server type, command/URL, and parameters
  3. Add Credentials: Environment variables for API keys and secrets
  4. Test Server: Validate connectivity and tool discovery
  5. Save to Registry: Add to Tool Registry for agent access

Testing Features

Before deploying MCP servers, 2LY provides built-in testing:

  • Connection Validation: Verify server starts and responds
  • Tool Discovery: Confirm available tools are detected
  • Test Execution: Run sample tool calls with mock data
  • Error Reporting: Detailed diagnostics for troubleshooting

Security

Credential Management:

  • Environment variables for sensitive data
  • Secrets stored encrypted
  • No credentials in agent code
  • Centralized credential rotation

Access Control:

  • Assign tools to specific agents
  • Tool-level permissions
  • Audit logging for all tool calls
