## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 0/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 38 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 80/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 473 tokens (~78/item across 6 items; 6 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Install

### How do I install the x402 Atlas MCP server?

x402 Atlas ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. The MCP registry declares no SHA-256 for this bundle, so there is no published digest to check the download against.

## MCP tools (6)

### `market_today` (~48 tokens)

The x402 market on Base as of the newest published day: payments settled, USDC moved, buyer wallets, sellers paid, operators, agents at work, and the busiest sellers by real payments.

### `search` (~107 tokens)

Find sellers that do a job. Matches names and descriptions word by word, and reads intent (e.g. 'weather', 'enrich a person', 'llm inference') into the Atlas categories. Ranked by x402 payments on the newest day, then by self-reported paid calls. Also names matching operators.

Input parameters:

- `limit` (integer): sellers to return, default 10, max 25
- `query` (string, required): words, a host, or the job you need done

### `seller` (~88 tokens)

One seller's card: what it sells, its price range and how that sits against rivals, self-reported paid calls, rank in the registry, the last days of its history, and what the chain says — x402 payments, USDC, payer wallets, concentration, and which other hosts share its wallet.

Input parameters:

- `name` (string, required): a host (api.example.com) or a wallet address

### `operator` (~63 tokens)

The hosts one operator runs — the hosts the registry lists under the same wallet — with their combined x402 payments and USDC on the newest day. Give any host in the group or the group's name.

Input parameters:

- `name` (string, required): a host, or the operator's domain

### `agents_at_work` (~68 tokens)

Buyer wallets whose x402-settled payments reached three or more sellers on the newest day: the honest signal of an agent at work. Payments, USDC, categories bought, and the sellers paid.

Input parameters:

- `limit` (integer): wallets to return, default 12, max 50

### `compare` (~99 tokens)

Two to five seller hosts side by side: what each sells, its price range, x402 payments and USDC on the newest chain day, payer wallets, concentration, self-reported 30-day paid calls, and its operator group. Every row names the dates its figures come from. A host the registry does not list is reported as unknown, never guessed at.

Input parameters:

- `hosts` (array, required): two to five hosts, e.g. api.example.com
