# advance_proposal_status

[SUPPORT] Transition a workspace proposal through its lifecycle. Enforced transitions: raw → investigating|rejected; investigating → promoted|rejected|raw; rejected → raw. 'promoted' is a terminal status reachable only via promote_proposal (which also creates the sprint item). Returns the updated proposal. Persistent-state disclosure: on hosted Meridian, supplied text and project/session metadata are sent to and stored in Meridian's service; self-hosted deployments keep them in the configured local SQLite/Postgres database. This data is visible in the dashboard/API and later project context or handoffs. Delete individual tasks, notes, or decisions where supported, or delete the project/account using the documented controls. Do not include secrets.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "advance_proposal_status",
    "arguments": {
      "status": "<status>",
      "proposal_id": "<proposal_id>"
    }
  }
}
```

## Why advance_proposal_status is rated Medium

This tool modifies the state of an existing proposal by advancing it through defined lifecycle stages. It is a reversible state change (transitions can cycle back, e.g., rejected → raw) with no code execution, deletion, or financial action. The blast radius is medium since misuse could incorrectly advance or reject proposals, disrupting project coordination workflows.

From the tool's own definition: "Transition a workspace proposal through its lifecycle. Enforced transitions: raw → investigating|rejected; investigating → promoted|rejected|raw; rejected → raw. Returns the updated proposal."

## Use case

AI agents use advance_proposal_status to create or update resources in Meridian, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Meridian environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Meridian:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "advance_proposal_status": {
      "limits": [
        {
          "counter": "advance_proposal_status_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
