# set_grain_policy

Create or update the wisdom-layer publish policy for ONE content grain in the current company. gate_mode 'human_pre_gate' reserves the grain for human approval; 'autonomous' lets an agent publish it directly. A brand-new grain defaults to human_pre_gate (fail-safe). Because this governs an agent's own publishing autonomy, the change routes to operator approval — it does not take effect silently. [sensitive-tier — first use may require a manager's approval; a from-now-on approval makes future calls seamless, a just-once approval re-asks next time.]

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `note` | string | no | Human-readable note on why this grain has this policy. |
| `grain` | string | yes | The content grain key, lowercase_with_underscores (e.g. faith_values, harness_education, professional). |
| `companyId` | string | yes | FreedomOS company id to act within (you must be a member). Required for company-scoped tools. |
| `gate_mode` | string | no | 'autonomous' = an agent may auto-publish this grain; 'human_pre_gate' = it must route to a human first. |
| `curate_only` | boolean | no | If true, an agent may only assemble this grain from source_corpus_ref, never originate de-novo content. |
| `source_corpus_ref` | string | no | For curate_only grains: the corpus an agent may assemble from (e.g. a knowledge collection key). |

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "set_grain_policy",
    "arguments": {
      "grain": "<grain>",
      "companyId": "<companyId>"
    }
  }
}
```

## Why set_grain_policy is rated Medium

This tool modifies policy settings that control agent publishing behavior. While it affects publishing autonomy, it is reversible (can be updated again), does not irreversibly delete data, does not execute arbitrary code, and does not move money. The approval requirement and 'fail-safe' default (human_pre_gate) mitigate risk.

From the tool's own definition: "Tool 'set_grain_policy' creates or updates a publish policy that governs publishing autonomy ('gate_mode' can be set to 'human_pre_gate' or 'autonomous')."

## Use case

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