Overview

AI-generated overview

A remote MCP server that pins key spans of an agent's context before compaction, audits what was lost, and re-injects or halts.

What you can do
  • Pin invariants verbatim before compaction, classifying and hash-pinning spans, or pin a single span at write time.
  • Compare post-compaction context against the pinned snapshot and get an Ed25519-signed receipt naming degraded or lost spans.
  • Restore degraded or lost spans verbatim, or halt on critical loss when allow is false, using the audit's signed receipt.
When to use it
Useful when an assistant works with long contexts that get compacted or summarized and important instructions, constraints or facts must survive. It suits workflows where you want an explicit, verifiable record of what was dropped and a way to restore it or stop the run.
Requirements
A remote streamable HTTP endpoint at textforagents.com; no packages, environment variables or headers are declared. The audit step is described as a metered event, so an account or billing arrangement may be involved.
Before you install
The audit is metered, so repeated use may incur charges. Re-injecting spans writes content back into the context, and halting can stop a run; both depend on the signed receipt from the audit. Context spans are sent to a third-party service.

Installation

In SourceWeft

  1. Open Compaction-loss audit 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%2Fcompaction-loss-audit/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
