## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `pubfi.route.execute`

- The name "pubfi.route.execute" says "execute": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Execute one exact GET or POST path through the authenticated PubFi account lane and the same Registry v2 matcher and typed executor as the HTTP gateway. Append :free only when the capability catalog publishes that exact account-scoped free variant.
```

### `pubfi.substrate.runtime_upgrade.verify`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Verify one reviewed Substrate System.apply_authorized_upgrade extrinsic through the authenticated account lane. Supply the expected Blake2b-256 hash of the FRAME System AuthorizedUpgrade code payload, not the active :code hash at the apply block. The server streams and discards provider runtime code, persists only a compact proof, and returns independent comparison evidence.
```

## Only reads (2)

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

### `pubfi.capabilities.get`

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

Description, as the server wrote it:

```untrusted-server-text
Return the full typed request, response, metering, and readiness contract for one exact capability id from the installed Registry generation.
```

### `pubfi.capabilities.list`

- The name "pubfi.capabilities.list" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Enumerate the complete installed Registry v2 catalog as deterministic compact pages. The server does not rank, infer intent, or choose a capability.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__pubfi__pubfi_capabilities_list",
      "mcp__pubfi__pubfi_capabilities_get"
    ],
    "ask": [],
    "deny": [
      "mcp__pubfi__pubfi_route_execute",
      "mcp__pubfi__pubfi_substrate_runtime_upgrade_verify"
    ]
  }
}
```
