## Findings

- **warn** Annotations that disagree with the tool in `find_alternatives` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "find_alternatives" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "find_alternatives" says "find": a word for reading.
```


## Can't be undone (1)

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

### `find_alternatives`

- The name "find_alternatives" says "find": a word for reading.
- The description's first verb is "open": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Open-source alternatives to an app, product or service ("Photoshop", "Notion", "Heroku", "Postman"), from the GitHub repos RepoAlerts tracks, with real star counts and growth. Optionally for a platform or constraint ("Mac", "self-hosted"). Repos whose own page lists that app as something they replace come first.
```

## Changes things (1)

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

### `trending_repos`

- 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
What's rising on GitHub right now: the repos that gained the most stars today, this week or this month, with star farms filtered out. Optionally only one topic (agents, models, infra, creative, desktop, web) or one kind (app, mcp_server, library…). Use it when the user asks what's new, hot, trending or taking off in open source.
```

## Only reads (2)

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

### `get_repo`

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

Description, as the server wrote it:

```untrusted-server-text
Everything RepoAlerts knows about one GitHub repository (owner/name or URL): what it is and who it's for, stars and recent growth, a summary of its star curve, licence, last push, the apps it can replace, Hacker News stories and similar repos. Use it to check a repo before recommending or installing it. If the repo isn't in the directory, it says so (it may be unknown or excluded for fake stars).
```

### `search_repos`

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

Description, as the server wrote it:

```untrusted-server-text
Find real, actively growing open-source GitHub repositories for a need described in plain words ("a calendar MCP server", "free Photoshop alternative for Mac", "self-hosted analytics"). Semantic search over the RepoAlerts directory, which leaves out repos with fake (bought or farmed) stars. Use it instead of recalling package or repo names from memory, whenever the user asks for a tool, library, app, framework or MCP server. Returns for each repo: what it is, who it's for, stars and stars gained in 24 hours and 7 days, licence, last push, its RepoAlerts page and GitHub URL.
```
