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. How we score → Why this is hard to score →

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

What is the Market Data (x402) MCP server?
Market Data (x402) is an MCP server listed in the public MCP registry as io.github.r0dell/market-data-mcp. Paid-per-call data for agents: trading calendars, futures, macro, LEI, VAT, risk events (x402). This page covers its PyPI package (x402-market-data-mcp).
Is the Market Data (x402) MCP server safe to use?
Market Data (x402) scores 69 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Market Data (x402) MCP server expose?
Market Data (x402) exposes 58 tools: catalog_list, payment_status, list_markets, list_futures_products, list_cot_markets, and 53 more. Their descriptions and schemas cost roughly 3,968 tokens of context every time the server is loaded.
Is the Market Data (x402) MCP server still maintained?
Market Data (x402) is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Market Data (x402) MCP server under?
Market Data (x402) declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
What did VerifyMCP test on the Market Data (x402) MCP server?
VerifyMCP ran 15 checks on Market Data (x402), covering Known CVEs, Install scripts, Dependency health, Source repository and 11 more. One item could not be completed, a gap on our side rather than a finding about Market Data (x402): Malware scan. Endpoint Security and Transport & Reachability do not apply to a PyPI package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
