Model Context Protocol (MCP) Server: io.github.solhammer/agent-toolbox

The io.github.solhammer/agent-toolbox MCP server provides 26 deterministic, offline pre-action safety gates for AI agents. Each gate issues a signed verdict, intended to be evaluated before an agent takes an action. The server is positioned around agent-tooling and AI-agents workflow checks, with focus on hallucination detection and LLM usage.

🛠️ Key Features

26 deterministic pre-action safety gates
Offline execution
Signed verdicts per gate

🚀 Use Cases

Pre-action safety validation for AI agents
Hallucination detection before allowing agent actions
Agent tooling in LLM-driven workflows

⚡ Developer Benefits

Predictable, deterministic gate behavior
Offline-friendly safety checking
Tooling aligned with MCP and developer-focused TypeScript/LLM stacks

⚠️ Limitations

Only described as a set of offline pre-action gates; no additional tools or runtime behavior beyond signed verdicts are specified.

Install

No clone or build needed:

json

{
  "mcpServers": {
    "agent-toolbox": { "command": "npx", "args": ["-y", "agentoolbox-mcp"] }
  }
}

Or build from source:

bash

git clone https://github.com/solhammer/agentoolbox
cd agentoolbox
pnpm install
pnpm --filter "agentoolbox-mcp..." build   # builds the server + its workspace deps

This produces packages/mcp/dist/index.js (use "command": "node" with its absolute path).
