    🛡️ MCP Server Starter & Safety Kit

    Example session with this skill installed

    I need to build a TypeScript MCP server that can interact with my local SQLite database. Ensure it has safety gates for write operations.

    • Read your context and instructions
    • Compiled the mcp server starter

    Generated TypeScript MCP scaffold

    • Tool 'query_db' (read-only): Strict schema validation enabled.
    • Tool 'update_db' (dangerous): Confirmation gate injected; requires manual approval payload.
    • Security Audit: 0 Critical, 0 High findings.
    • Guardrails: Permission boundaries set to local DB path.

    Connects securely to your tools. The creator never sees your data.

    About this skill

    Build and Audit Secure MCP Servers

    The Model Context Protocol (MCP) allows AI agents to interact with local tools, but connecting an LLM to your file system or APIs involves significant security risks. The MCP Server Starter Safety Kit provides a production-ready framework for scaffolding and auditing MCP servers with native security guardrails.

    What it does

    This skill automates the creation of high-quality MCP server scaffolds in Python or TypeScript. Beyond simple templating, it acts as a security engineer for your agentic tools, performing heuristic scans and manual audits of tool definitions to ensure they don't perform "jailbreakable" actions without user oversight.

    Key Features

    • Heuristic Scanner: Runs a local read-only scan to detect unsafe patterns in your tool implementations.
    • Confirmation Gates: Automatically injects middleware and logic for dangerous actions (deletes, payments, system resets) that require explicit user approval.
    • Safe Schemas: Generates strict JSON input schemas to prevent prompt injection and unauthorized command execution.
    • Audit Documentation: Produces severity-ranked findings with remediation snippets and verification steps for existing MCP projects.

    Why use this skill?

    Prompting an AI to "write a tool" often results in insecure code with broad permissions. This skill enforces a "security-first" architecture, ensuring your agents operate within strict boundaries and provide clear logging for every action they take. It turns raw scripts into professional, safe, and auditable MCP servers.

    How to use

    1. 1

      Connect your agent to the Agensi MCP

      Copy the prompt and paste it into Claude, ChatGPT, Cursor or any agent that supports MCP. It sets up the connection for you. Manual setup

    2. 2

      Sign in to Agensi

      Your agent shows a sign-in link. Sign in and click Allow.

    3. 3

      Ask for what you need

      Your agent loads this skill and uses it on your task. It always asks before any payment.
