Context7 MCP Server

Solid all-round agent support with no single blocker.

Read-only by definition and that is the product — the cheapest accuracy upgrade you can give a coding agent.

What an agent can do here

Upstash's documentation MCP server — agents pull current, version-correct library docs instead of relying on stale training data.

Action depth
Read only

Agents can query data but cannot change anything.

Hosting
Vendor-hosted

Connect with a URL — nothing to install.

Auth
No auth
Unattended
Headless-capable

A long-lived token works, so this can run on a schedule.

Blast radius
Low

Trivially reversible.

Permission scoping: All or nothing

What it costs to let an agent act

FreeUsage-metered

Free tier available; an optional API key raises rate limits.

PlaywrightExcellentThe rare zero-friction entry: official, free, no auth. It loses points only because there is no hosted API or llms.txt — neither of which it needs.
