## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `check_dependency_upgrade`

- 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
Use when a coding agent needs a cited go/no-go risk decision without steps before changing an existing npm or PyPI dependency between two exact versions. Returns action_allowed, vulnerability delta, compatibility, EOL, and breaking-change evidence. Use plan_dependency_upgrade instead for ordered migration work. Do not use to choose a target, install a new package, search general docs, or analyze another ecosystem. Read-only and safe to retry.
```

### `plan_dependency_upgrade`

- 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
Use when a coding agent needs a migration checklist, refactor actions, ordered review actions, changelog links, or test steps for exact current and target npm/PyPI versions. Use check_dependency_upgrade instead for a go/no-go without steps. Do not use to choose a target, install a package, or provide a general tutorial. Read-only and safe to retry.
```

### `review_dependency_upgrade`

- 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
Use when an agent reviews a Dependabot, Renovate, npm, or PyPI version change before merge. One cited result combines security delta, runtime compatibility, breaking changes, go/no-go risk, and ordered migration actions for exact current and target versions. Do not use for new installs, unknown versions, general documentation, or other ecosystems. Read-only and safe to retry.
```

## Only reads (1)

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

### `find_safe_upgrade_target`

- The name "find_safe_upgrade_target" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use only when an existing npm or PyPI dependency has an exact current version but no chosen target. Ranks candidates; candidates are not declared safe and require check_dependency_upgrade or plan_dependency_upgrade. Do not use when a target is stated, for a new install, or as authorization to edit files. Read-only and safe to retry.
```

## Claude Code permissions

      "mcp__upgradelens__find_safe_upgrade_target"
    ],
    "ask": [
      "mcp__upgradelens__review_dependency_upgrade",
      "mcp__upgradelens__check_dependency_upgrade",
      "mcp__upgradelens__plan_dependency_upgrade"
    ],
    "deny": []
