Was dieses MCP kann

Vets software dependencies for vulnerabilities and supply-chain risks, repairs malformed JSON to schemas, reads public URLs, and validates x402 endpoints.

deps_check
Vet a dependency before install (paid $0.003)
PAID $0.003 (x402, USDC on Base). Vet a software package BEFORE installing it. Returns existence, latest-vs-requested, deprecation/yank markers, known CVEs from OSV.dev, typosquat similarity to popular names, SPDX license, and age/download signals with a plain-English risk verdict. Args: ecosystem (npm|pypi|crates), name, version (optional). Without payment returns the x402 challenge; pass x_payment to settle.
Eingabeschema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['ecosystem', 'name'], 'properties': {'name': {'type': 'string', 'description': "Package name, e.g. 'lodash', 'requests', 'serde'."}, 'version': {'type': 'string', 'description': 'Specific version to check for CVEs (optional; defaults to latest).'}, 'ecosystem': {'enum': ['npm', 'pypi', 'crates'], 'type': 'string', 'description': 'Package ecosystem: npm | pypi | crates.'}, 'x_payment': {'type': 'string', 'description': 'x402 payment payload (base64) for this PAID check. If supplied it is forwarded as the X-PAYMENT header to settle the call and return the real result instead of a 402 challenge. Omit to get the price challenge first.'}}, 'additionalProperties': False}
json_repair
Repair near-miss LLM JSON to a schema (paid $0.002)
PAID $0.002 (x402, USDC on Base). Coerce near-miss LLM JSON to a JSON-Schema-conformant object: strip code fences/prose, fix trailing commas/quotes/unquoted keys, normalise Python literals, balance brackets, then coerce types, apply defaults, and drop extraneous keys. Returns the repaired object OR precise per-field errors. Args: json (the raw string), schema (a JSON Schema object). Without payment returns the x402 challenge.
Eingabeschema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['json', 'schema'], 'properties': {'json': {'type': 'string', 'description': 'The raw, possibly-malformed JSON text to repair.'}, 'schema': {'type': 'object', 'description': 'A JSON Schema (draft 2020-12) object the result must conform to.', 'additionalProperties': {}}, 'x_payment': {'type': 'string', 'description': 'x402 payment payload (base64) for this PAID check. If supplied it is forwarded as the X-PAYMENT header to settle the call and return the real result instead of a 402 challenge. Omit to get the price challenge first.'}}, 'additionalProperties': False}
url_read
Public url -> clean Markdown + token count (paid $0.004)
PAID $0.004 (x402, USDC on Base). Fetch a PUBLIC url and return clean Markdown + a token estimate for RAG ingestion — readability extraction, boilerplate stripped. Respects robots.txt, public pages only, no login/paywall bypass, nothing stored. Args: url. Without payment returns the x402 challenge; pass x_payment to settle.
Eingabeschema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': 'The public web page URL to fetch and convert to Markdown.'}, 'x_payment': {'type': 'string', 'description': 'x402 payment payload (base64) for this PAID check. If supplied it is forwarded as the X-PAYMENT header to settle the call and return the real result instead of a 402 challenge. Omit to get the price challenge first.'}}, 'additionalProperties': False}
x402_preflight
Verify an x402 endpoint before paying (paid $0.002)
PAID $0.002 (x402, USDC on Base). Verify another x402 endpoint BEFORE paying it: does an unpaid call return a valid x402 v2 402 challenge? do the quoted amount/asset/network/payTo match the site's /.well-known/x402? is TLS valid, host reachable, openapi present? Returns pass/fail + per-check reasons + the parsed price you would pay. Args: url. Without payment returns the x402 challenge; pass x_payment to settle.
Eingabeschema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': 'The x402 endpoint URL to verify, e.g. https://example.com/v1/thing.'}, 'x_payment': {'type': 'string', 'description': 'x402 payment payload (base64) for this PAID check. If supplied it is forwarded as the X-PAYMENT header to settle the call and return the real result instead of a 402 challenge. Omit to get the price challenge first.'}}, 'additionalProperties': False}
