Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "attestd": {
      "command": "npx",
      "args": [

Run this in your terminal

claude mcp add attestd --env ATTESTD_API_KEY=your-value --env ATTESTD_BASE_URL=your-value -- npx -y @attestd/mcp

Fill in the empty values before running it.

Open in Cursor

Common questions

Is Attestd MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ATTESTD_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.1) reached the registry 43 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@attestd/mcp

Attestd checks whether a dependency version has exploitable CVEs or a confirmed supply-chain compromise. One API call returns a structured risk response.

Official Model Context Protocol (MCP) server for Attestd. Exposes CVE risk and supply-chain checks as tools for Claude Code, Claude Desktop, and any MCP-compatible client.

Get a free API key · Full docs

stdio transport: run via npx -y @attestd/mcp with no global install.
`check_package_vulnerability`: wraps GET /v1/check using @attestd/sdk.
`check_batch_vulnerabilities`: checks up to 100 packages in one call. Use for lockfile and manifest audits.
`list_covered_products`: returns Attestd-covered products. With an API key, returns live data from GET /v1/products. Without a key, returns the static bundled infrastructure list.
`get_cve_details`: returns CVSS, EPSS, KEV status, and affected products for a single CVE id.
`get_usage`: returns remaining quota for the authenticated key (GET /v1/usage).

Prerequisites

Node.js 18+
An Attestd API key from the portal. Required for check_package_vulnerability, check_batch_vulnerabilities, get_cve_details, get_usage, and live list_covered_products.

Claude Code / MCP config

Add to ~/.claude/mcp.json or project .mcp.json:

"mcpServers": { "attestd": { "command": "npx", "args": ["-y", "@attestd/mcp"], "env": { "ATTESTD_API_KEY": "your-api-key-here" } } } }

Optional: override the API base URL (e.g. dev):

"env": {

"ATTESTD_API_KEY": "your-api-key-here", "ATTESTD_BASE_URL": "https://dev.api.attestd.io" }

Tools

`check_package_vulnerability`

Argument	Type	Description
`product`	string	Product slug (`nginx`, `postgresql`, `litellm`, …)
`version`	string	Exact version (`1.20.0`)

Returns JSON with:

Field	Meaning
`outsideCoverage`	`true` if the product is not covered. Unknown risk, not safe.
`riskState`	`critical` \	`high` \	`elevated` \	`low` \	`none` \	`null` when outside coverage
`riskFactors`	Risk factor vocabulary driving `riskState`
`maxEpss`	Highest EPSS probability across matching CVEs
`activelyExploited`	CISA KEV signal
`remoteExploitable`	`true` if any matching CVE is remotely exploitable
`authenticationRequired`	`true` only when all matching CVEs require authentication
`patchAvailable` / `fixedVersion`	Patch guidance
`confidence`	Synthesis confidence 0.0–1.0
`cveIds`	CVE IDs contributing to the risk assessment
`typosquat`	Package name integrity: `detected`, `resembles`, `confidence`, `ecosystem` (SDK 0.5 runtime; extra fields are omitted)
`message`	Explanation when `outsideCoverage` is true
`supplyChainCompromised` / `supplyChainDescription`	PyPI/npm supply-chain signal

On invalid/missing API key or rate limit, returns isError: true with a JSON error string.

`check_batch_vulnerabilities`

Argument	Type	Description
`items`	array	Array of `{ product, version }` objects. Maximum 100 per call. Each item costs one API call.

Quota is checked upfront. If the batch would exceed your monthly quota, a 429 is returned before any calls are billed.

Returns JSON with count and results. Supported items include the same fields as check_package_vulnerability minus typosquat. Outside-coverage items return only product, version, outsideCoverage: true, and riskState: null.

`list_covered_products`

No arguments. With an API key, returns live JSON from GET /v1/products:

Field	Meaning
`source`	`"live"` when fetched from the API
`total`	Combined count of CVE products and supply chain packages
`cveProducts`	CVE infrastructure slugs with display names
`supplyChainPackages`	Monitored PyPI/npm packages

Without an API key, returns the static bundled list:

Field	Meaning
`source`	`"static"`
`count`	Number of bundled infrastructure products
`products`	Array of `{ slug, display }` entries

`get_cve_details`

Argument	Type	Description
`cve_id`	string	CVE identifier, e.g. `CVE-2021-44228`

Returns JSON with:

Field	Meaning
`found`	`true` when the CVE is in Attestd's database; `false` on 404 (not an error)
`cveId`	CVE identifier
`description`	NVD description text
`cvssScore` / `cvssVector`	CVSS base score and vector
`activelyExploited`	CISA KEV signal
`remoteExploitable`	Remotely exploitable
`authenticationRequired`	Authentication required for exploitation
`affectedProducts`	Attestd product slugs affected by this CVE
`epssScore` / `epssPercentile`	EPSS probability and percentile
`sourcePublishedAt` / `lastCheckedAt`	ISO timestamps

When the CVE is not found, returns { "found": false, "cveId": "..." } without isError. On invalid/missing API key or rate limit, returns isError: true with a JSON error string.

`get_usage`

No arguments. Requires an API key. Returns JSON from GET /v1/usage:

Field	Meaning
`tier`	Account plan tier
`keyCallsThisMonth`	Calls billed to this key in the current period
`accountCallsThisMonth`	Calls billed across all keys on the account
`includedCalls`	Monthly included call cap
`billingPeriodStart` / `billingPeriodEnd`	ISO timestamps
`overageCalls` / `estimatedOverageUsd`	Overage vs the included cap

On invalid/missing API key or rate limit, returns isError: true with a JSON error string.
