Overview

AI-generated overview

Remote MCP server that lets an assistant screen outbound agent messages for worm-like propagation, check payload fingerprints, and read fleet spread telemetry.

What you can do
  • Score outbound messages against inbound context and quarantine worm-like forwards
  • Look up whether a payload fingerprint has been seen propagating across the fleet
  • Write to and read from a shared store, with reads returning data context unless a valid elevation token is given
  • Report per-cluster spread telemetry and R estimates
  • Verify that loop-breaking controls are enabled and untampered
When to use it
For teams running fleets of agents that want an assistant to check messages before they leave, trace known payloads, and watch how far something is spreading across clusters.
Requirements
A remote streamable HTTP endpoint at the provider's site; no packages, environment variables, headers or authentication are declared. Network access to the provider is required.
Before you install
The server writes to a shared store and reads from it, so data can be changed and exposed; reads are only data context unless an elevation token is supplied. Outbound message content is sent to a third-party service for scoring, and fingerprint queries reveal payload identifiers. No authentication is declared, so anyone reaching the endpoint may use it.

Installation

In SourceWeft

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

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.textforagents%2Fpropagation-breaker-agent-worms/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

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.
