Overview

AI-generated overview

A remote MCP server that gives an assistant searchable guidance for answering vendor security questionnaire questions, with standards and control references.

What you can do
Search the questionnaire corpus by question text, control area, or standard and control identifier, with the source page for each match. Retrieve full guidance for one question: what it asks, which documents answer it, evidence to attach, a model answer, common pitfalls, and cited standards. List the standards covered, their question counts and cited controls. Read FillTrust's own vendor answers, including negative ones. View measured statistics from 146 real questionnaires on the most-asked topics and named questionnaire profiles.
When to use it
Useful when drafting or reviewing responses to vendor security questionnaires such as HECVAT or CAIQ, or when you want to know which topics and controls questionnaires commonly ask about. Also handy for assessing FillTrust itself as a vendor. Not a tool for filling in or submitting questionnaires automatically.
Requirements
A remote streamable HTTP endpoint; no packages, environment variables or headers are declared, and no authentication is declared. Network access to the provider's endpoint is needed.
Before you install
Results include links to the source page for each entry, and the corpus is third-party content that should be checked against your own policies before reuse. The posture tool returns FillTrust's own vendor answers, including negative ones, so treat it as vendor-supplied material. No credentials are requested.

Installation

In SourceWeft

  1. Open FillTrust security questionnaire corpus in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.filltrust%2Fquestions/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

The complete published guidance for one questionnaire question: what it is really asking, which of your documents answers it, what evidence to attach, a model answer with the specifics left blank, the ways it usually goes wrong, and the standards that ask it with their verified control references.

Parametersslugrequired

list_standards

List the standards the corpus covers

Which questionnaire standards this corpus answers questions from, how many questions each has, and which controls are cited. Standards whose control lists are proprietary are named without reference numbers, on purpose.

get_questionnaire_statistics

What security questionnaires actually ask, measured

Measured counts from 146 real vendor security questionnaires (17,697 questions) published by universities, purchasing consortia and companies: which topics are asked most, and detailed profiles of the questionnaires that have a name people use, such as HECVAT and CAIQ. Use this when asked what a security questionnaire contains, how long one is, or what a named questionnaire asks about. These are counts from real files rather than an estimate.
