Declaw Ai MCP Server

Declaw MCP Server

MCP server for Declaw — secure sandbox execution for AI agents with network policies, PII scanning, prompt injection defense, and audit logging.

Works with Claude Desktop, Claude Code, Cursor, Windsurf, and any MCP-compatible AI tool.

Quick Start

Claude Desktop / Cursor / Windsurf

Add to your MCP config:

{
  "mcpServers": {
    "declaw": {
      "command": "npx",
      "args": ["-y", "@declaw/mcp-server"],
      "env": {
        "DECLAW_API_KEY": "your-api-key"

Tools

Security Presets

When creating a sandbox, choose a security preset:

• none — No guardrails. Full internet access.
• standard (default) — PII scanning + audit logging. Full internet access.
• strict — PII scanning + prompt injection defense + audit logging + network deny-all.

You can also pass allowed_domains to restrict outbound traffic to specific domains:

create_sandbox with template="python", security_preset="strict", allowed_domains=["pypi.org", "github.com"]
