# unarchive_project

Restore an archived project you own to the data plane. Restoring consumes one of your plan's active-project slots, so at the limit this returns an error telling you to archive another project or upgrade. Idempotent for an already-active project. Requires an ACCOUNT-scoped token and the config scope.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {

## Why unarchive_project is rated Medium

The tool creates a state change (archived → active) in the system, making it a Write operation rather than a Read. It is not Destructive because unarchiving is reversible (the project can be archived again). It is not Financial, though it does mention plan slots and limits, as the financial transaction (if any) occurs at subscription time, not here.

From the tool's own definition: "Tool description states it will 'Restore an archived project you own to the data plane,' which modifies the state of a project by moving it from archived to active status."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json

  "tools": {
    "unarchive_project": {
      "limits": [
        {
