## Findings

No check matched anything in these tool definitions.


## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `get_brand_signals`

- The name "get_brand_signals" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs the recent harvested signals (each with text, tier, score, and source URL) backing a brand's score. Public-citable signals only — internal-only items are filtered before emit. Always carries a coverage_status describing why a list may be empty.
```

### `get_competitive_context`

- The name "get_competitive_context" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs a brand's competitor set, peer momentum snapshots, and a deterministic competitive-position one-liner. Excludes peers without real signal coverage (scaffold tier). Always carries a coverage_status describing the result.
```

### `get_momentum_index`

- The name "get_momentum_index" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs Persimmon's deterministic momentum score for a specific brand or the top of the index. Returns composite score plus four dimensions (Draw, Surge, Wedge, Hold), tier band, signal count, and last-updated timestamp. Pure read; no LLM calls in scoring.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `persimmon`:

```json
{
  "permissions": {
    "allow": [
      "mcp__persimmon__get_momentum_index",
      "mcp__persimmon__get_brand_signals",
      "mcp__persimmon__get_competitive_context"
    ],
    "ask": [],
    "deny": []
  }
}
```
