Every tool here is either a useful pipe between agents and real software, or a weekend repo dressed up like infrastructure. We read the source, check the maintainer, and say which is which. Aggregators may point us to a tool; the repo is the record.
MCP servers can read files, call APIs, and act with your credentials, depending on configuration. Inspect the source before installing, and never paste secrets into a tool you haven’t read.

Anthropic's collection of agent skills — folders of instructions and scripts that teach Claude document creation and other repeatable crafts. Less software, more standard operating procedure.
The reference web-fetch server: give an agent a URL, get back the page as readable markdown. Small, honest, and easier to misuse than it looks.
The reference server that gives an agent read/write access to your disk, fenced to directories you name. Simple, official, and the single sharpest tool in the drawer.
The reference server for local git — status, diff, log, commit, and branch operations on repositories you point it at. Your history becomes agent-writable, which is most of the point and all of the risk.
The reference memory server — a local knowledge graph where your agent files entities, relations, and observations between sessions. Simple, inspectable, and exactly as smart as what gets put in it.
A reference server that gives the model a numbered, revisable scratchpad for working through hard problems — thought, revise, branch, conclude. No network, no files, just protocol.
Feeds your agent current, version-specific library docs instead of whatever it half-remembers from training. Fixes a real failure mode — by routing your questions through someone else's service.
Microsoft's browser-automation server — agents drive a real browser through the accessibility tree instead of squinting at screenshots. Fast, deterministic, and a genuinely good idea.
GitHub's official MCP server — lets an agent read repos, file issues, and push code with your credentials, which is exactly as useful and as dangerous as it sounds.
Notion's official server — your agent reads, searches, and writes pages and databases with an integration token you scope. The wiki becomes writable by software; decide how you feel about that first.
