Endpoint Security83
Transport & Reachability100
Schema Quality & AI Usability79
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 12959 tokens (~172/item across 75 items; 65 tools + 10 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage97
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 90% of tool parameters carry a description.Partial
  • Structured output schemas are declared (11% of tools); any adoption earns full credit.Pass
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "x402_pay_guard" implies "pay" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Fail
  • An AI judge read all 67 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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 →

Install

How do I install the Factline MCP server?

Factline is a hosted endpoint at https://factline.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Common questions

What is the Factline MCP server?

Factline is an MCP server listed in the public MCP registry as io.github.snefhew/factline. Checks before an agent pays: payees, webshops, invoices, payment files, companies, sanctions, PEP. This page covers its hosted endpoint (https://factline.dev/mcp).

Is the Factline MCP server safe to use?

Factline scores 88 out of 100 on VerifyMCP. 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 Factline MCP server expose?

Factline exposes 65 tools: nl_home_basic, x402_pay_guard, watch_alerts, x402_sellers, get_trial_key, and 60 more. Their descriptions and schemas cost roughly 12,515 tokens of context every time the server is loaded.

Does the Factline MCP server require authentication?

No. We connected to Factline without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Factline MCP server still maintained?

Factline 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.
