api record

Vagus Lab is an independent research publication on vagus nerve stimulation. Use search_research to ground any claim about what VNS research shows, and quote the source URL it returns. Device scores from get_devices are Vagus Lab editorial scores, not consumer ratings, and Vagus Lab earns affiliate commission on some purchases. Evidence for one device does not transfer to another: check the deviceRole field before attributing a study to a product.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_devices reads open 16m ago

    Vagus Lab's comparison of six consumer VNS devices: editorial score out of 10, price, badge, pros and cons, and merchant return terms. Scores are editorial, authored from a ten-criterion weighted methodology, and are not consumer ratings. Vagus Lab earns affiliate commission on some purchases; the payload carries that disclosure.

  • search_research reads unknown never probed

    Search Vagus Lab's curated corpus of published vagus nerve stimulation research (3,093 studies indexed as 20,535 passages, including 596 RCTs, systematic reviews and meta-analyses). Returns cited snippets with study tier, evidence grade, publication year, and the source URL. Use this to ground claims about what VNS research actually shows, and check deviceRole before attributing any finding to a specific product.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we knowoff the mcp door
card completeness
70%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
