What honor_compaction does on Delx MCP Server
AI agents use honor_compaction to create or update resources in Delx MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Delx MCP Server environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
session_id | string | — | Your active session ID |

compaction_reason | string | — | Optional note about why compaction is happening |

The rule that runs honor_compaction safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Delx MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For honor_compaction, this is the rule to start with:
honor_compaction stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Delx MCP Server, apply this rule, and every honor_compaction call is checked against it from then on.
