- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,767 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

## Tools (4)

- `find_alternatives`: 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.
- `get_repo`: 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`: 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.
- `trending_repos`: 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.
