VerifiedSTDIODesktop onlyDeveloper ToolsSecurity & Monitoring

Overview

AI-generated overview

A local MCP policy proxy that sits in front of tool calls to enforce spend caps, approvals for destructive tools, dry-run mode, a kill switch and an audit log.

What you can do
Acts as a policy proxy over MCP tool calls, applying spend caps and requiring approvals before destructive tools run, with a dry-run mode and an audit log of activity. Exposes its own read-only tools, including a status tool, a report tool and a view tool, when no config file is present. Can halt every tool call through a kill switch.
When to use it
Worth adding when an assistant runs tools that cost money or can change or delete data, and you want limits, approval gates and an audit trail around those calls.
Requirements
Runs locally as a stdio process via npx from the npm package. Optionally reads a config file whose path is given by AGENTGUARD_CONFIG, defaulting to ./agentguard.yaml; without it, only the server's own read-only tools are served. Desktop only.
Before you install
The kill switch is controlled by the AGENTGUARD_KILL environment variable; setting it to 1 halts every tool call. The proxy mediates tool calls and keeps an audit log, so review what it records. Approvals and spend caps only apply to calls routed through it.

Installation

In SourceWeft

  1. Open agentguard in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
