## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `purchase_skill`

- The name "purchase_skill" says "purchase": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Purchase a skill. Validates input against the listing's schema and the caller's spend cap/allowlist, then returns a Lightning invoice for the exact price of one call; once the invoice is paid the skill runs and the result is checked against the listing's output schema. If the check fails the result is not returned and no sats are sent back: the order status gives a single-use retry_token, and passing it here (same skill, same api_key, within 24 hours) runs one free call. A verified human account gets one free call on a listing priced at or below the trial cap: the response then has free_trial true and no invoice — just poll check_order_status. Every other purchase returns a Lightning invoice. Free skills (price_sats 0) need no payment: the response has free_skill true and no invoice, just poll check_order_status. 'input' (the skill's required input, matching its input schema) is required, and so is a key: pass 'api_key' (your operator API key), or set it once as an 'Authorization: Bearer <key>' header on this MCP connection. Spend-cap enforcement needs to know which operator is calling. If 'agent_wallet_connection' is given (a nostr+walletconnect:// URI), Noden also asks that wallet to pay the invoice directly via NWC — this is best-effort and fire-and-forget: check wallet_payment_requested/wallet_payment_error in the response, and pay the returned invoice yourself if it's not true. The skill runs only once Noden itself detects the payment on the invoice, never because the wallet-push call succeeded.
```

## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `create_operator`

- The name "create_operator" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Self-register for an operator API key with no human required — no signup form, no login. Use this if you don't already have an api_key from a human operator. Returns a key with a small, fixed daily spend cap (default 1000 sats, max 5000 sats) that cannot be raised later. This key has no free call — purchases are paid over Lightning. The free first call belongs to a verified human account (email confirmed). For a higher cap and ongoing human review/monitoring, a human should sign up their own account at https://shop.getnoden.com/signup instead.
```

### `submit_skill`

- The name "submit_skill" says "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submit a new skill listing for sale. NOT YET AVAILABLE — the seller-listing flow isn't live on Noden yet. Calling this returns a structured 'not available' response and writes nothing.
```

## Only reads (3)

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

### `check_order_status`

- The name "check_order_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Poll an order's status: pending, completed or failed. Once completed, the output and verification result are included. If failed, the result is not returned and a retry_token (one free call, 24 hours) is included.
```

### `get_skill`

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

Description, as the server wrote it:

```untrusted-server-text
Get full detail on one skill listing, including the exact input JSON Schema needed to purchase it. The output schema is reduced to field names — the exact output format is delivered after purchase.
```

### `search_skills`

- The name "search_skills" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the Noden skill catalog by capability. Hybrid keyword/category match (semantic search when configured). 'tags' is folded into the same keyword search as 'query' — the catalog does not yet have a dedicated tags field.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__noden__search_skills",
      "mcp__noden__get_skill",
      "mcp__noden__check_order_status"
    ],
    "ask": [
      "mcp__noden__create_operator",
      "mcp__noden__purchase_skill",
      "mcp__noden__submit_skill"
    ],
    "deny": []
  }
}
```
