MCP policy proxy: spend caps, approvals for destructive tools, kill switch, dry-run, audit log.
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.
Installation
In SourceWeft
- Open agentguard in the dashboard and add it to a workspace.
- 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.

Score
25% of the applicable checks met
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.
- Reached in the last 30 days25 pts
Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.
- Auth declared10 pts
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
