## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `nebula_overview`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Organisation facts (name, founding year, location, public contacts), founders, services, industries and frameworks of Nebula Personalization Tech Solutions Pvt. Ltd.
```

## Only reads (2)

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

### `nebula_search`

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

Description, as the server wrote it:

```untrusted-server-text
Keyword search across Nebula organisation, services, industries, frameworks, Answers and blog titles. Returns up to 6 matching records with their section path.
```

### `nebula_section`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return one section or record by dotted path. Sections: organization, people, services, industries, frameworks, research, externalAssets, answers, blogs. Examples: "services", "answers.4", "organization.address".
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__nebula__nebula_search",
      "mcp__nebula__nebula_section"
    ],
    "ask": [
      "mcp__nebula__nebula_overview"
