What this server can do

15 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

audit_comp_live_listings: Return a curated snapshot of currently-live audit competitions and bug-bounty programs across Code4rena, Cantina, Sherlock, and direct-protocol channels. Useful for solo wardens triaging which contests to enter. Snapshot updates with each cipher-x402-mcp release; treat the data as a hint, always cross-check the platform before submitting. Free, no payment required.
check_drift_exposure(wallet, _payment): Check a Solana wallet's exposure to Drift Protocol — open perp positions, collateral, unrealized PnL, liquidation risk distance. Priced at $0.01 USDC on Base (x402). Pass a signed x402 v2 authorization as the '_payment' argument to unlock the paid response. Without it, the tool returns the 402 accept-list for your wallet to sign. Required: wallet.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

Signal	Value	What it measures	Window	Observed	Source
GitHub stars	0	Number of GitHub accounts that bookmarked this repository since it was created. It is a bookmark count, not installs, not active users and not quality.	cumulative, all time	2026-08-06	GitHub
Last commit	2026-04-26	Date of the most recent push to any branch. This is the strongest cheap indicator of whether the project is still maintained.	point in time	2026-08-06	GitHub
Open issues	0	Open issues plus open pull requests, as GitHub counts them together. A high number can mean an active project or an abandoned one.	as of fetch	2026-08-06	GitHub
Latest published version	0.1.0	Latest version string the maintainer published to the registry.	as of fetch	2026-04-17	Model Context Protocol
Registry record last updated	2026-04-17	When the registry record was last updated by its maintainer.	point in time	2026-04-17	Model Context Protocol

First listed in the MCP Registry	2026-04-17	Date this server was first published to the official MCP Registry. Not a usage or quality measure.	point in time	2026-04-17	Model Context Protocol
repository status	active	The repository exists on GitHub and is not archived. This says nothing about how recently it was worked on.	as of fetch	2026-08-06	GitHub
mcp tools declared	15 tools	Number of functions the server itself declared when asked to list them. This is what the server offers an agent, not a measure of how well any of them work.	as of probe	2026-08-09	cipher-x402-mcp.vercel.app
mcp endpoint status	ok	The server listed 15 functions when asked.	as of probe	2026-08-13	cipher-x402-mcp.vercel.app

These share tags the maintainers applied themselves, such as base, paid-api, usdc, x402. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
