Agentguard47 MCP Server
Stop runaway agents with runtime checks in Python. AgentGuard checks budgets, repeated tool calls, retries, and elapsed time in instrumented Python code. Guards raise exceptions so your application can stop the next operation. The base SDK has no runtime dependencies and needs no account. It runs locally over stdio via the published package.
People who work with ai safety, developer tools and guardrails and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Agentguard47
Claude Code
claude mcp add bmdhodl-agent47 -- npx -y @agentguard47/mcp-serverClaude Desktop / Cursor / VS Code - add to config

Security posture
What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

npm package @agentguard47/mcp-server - the @agentguard47 scope differs from the repo owner (bmdhodl); confirm it's the project's official package
registry namespace io.github.bmdhodl is GitHub-verified and matches the repo owner
