The directory for
AI agent tools.
MCP servers are eating the agent stack. Quiver indexes them all and polygraphs the risky ones — so your agent installs with receipts, not vibes.

Three ways Quiver protects your agent.
Directory, polygraph, and a public review market — one stack instead of three dashboards.
Every MCP, one URL.
Real packages from npm, refreshed hourly. The directory is live, the count is real, and the categories are wired to filters that actually work.
A public letter grade.
Each server is run through a sandboxed adversarial probe (tool-output injection, permission overreach, sensitive-data handling). You see the grade; the evidence is one click away.
A public review market.
Every MCP has a public review thread. Reviewers build reputation over time; the directory learns which voices to trust and which to ignore. No token required to start.
The MCP ecosystem grew faster than the audit layer.
Thousands of MCPs ship every quarter. Most never get independently tested. The few audits that exist live in vendor blogs, paywalled, or behind a Discord gate. Quiver is the public, evidence-first default your agent already needed.
- ·Every grade ships with a sha256 tool-surface fingerprint.
- ·Server changes a tool → grade goes stale automatically.
- ·Public review threads you can read before installing.
- ·The CLI does the lookup before your agent installs anything.
