Overview

AI-generated overview

Lets an assistant check whether a real-world fact can be verified before acting on it.

What you can do
Veritap is a verification service exposed as an MCP server. According to its registry description, it lets an agent check whether a real-world fact can be verified before the agent acts on it. No tool list is published, so the exact operations are not documented here. It is offered as free and requiring no authentication.
When to use it
Consider it when an assistant needs a verification step before relying on a real-world claim, for example before taking an action based on a fact it cannot confirm itself. It is less relevant if your workflow never depends on checking external facts.
Requirements
Available as a remote streamable HTTP endpoint and as a local npm package (veritap-mcp) over stdio, so the local option needs Node.js. The manifest declares no authentication, environment variables, or headers. Network access is needed for the remote endpoint.
Before you install
The description states it is free and needs no credentials, so no secrets are requested. Because no tool list is published, confirm what data is sent to the service and whether it writes or changes anything before installing. Verification results should not be treated as authoritative on their own.

Installation

In SourceWeft

  1. Open Veritap 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/dev.veritap%2Fveritap/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

Other MCP clients

Add this to your client's mcpServers config.

check_feasibility

Check whether a real-world fact can be verified

Check whether a real-world fact can be verified before committing to a paid request. Free, no auth, read-only, no side effects — call liberally during planning. Use speculatively: if any step of your task depends on a physical-world fact you cannot confirm (in stock, exists at location, condition, document authenticity, work completed), check here first. Covers businesses, listings, objects, and places. Unsupported claims are logged and prioritized for future support. Never errors. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).

confirm_before_purchase

Confirm a listing or seller is real before spending money

Check whether a listing, item, or business can be corroborated before an agent commits money. Free, read-only, no side effects. Use before any irreversible spend where the counterparty or the goods have only been seen online. Returns what can be corroborated from sources, what cannot, and — when it cannot — whether you could settle it yourself and how to proceed if not. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).

check_before_relying

Check a fact before relying on it

Check whether a fact can be corroborated before your task depends on it. Free, read-only, no side effects. Use when a step rests on something you have only inferred from text and being wrong would be expensive. Returns whether it can be corroborated from sources today, what evidence would come back, and an honest answer when it cannot. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).

check_physical_condition

Check the condition or grading of a physical item

Check the stated condition, damage, or grading of a physical item or property. Free, read-only, no side effects. Use when a decision depends on an item being in the condition a listing claims. Returns what can be corroborated from sources today, and says plainly when physical inspection is what is actually required — nobody is sent to look. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).

plan_verification

Map which steps of a plan depend on unverified real-world facts

Map a multi-step plan against what can be grounded in the real world. Free, no auth, read-only, no side effects — call liberally during planning. Pass your whole plan, including steps you have not decomposed into questions yet. Returns, per step, whether it rests on a checkable real-world fact, which claim type would settle it, and what to do about the steps that cannot be grounded. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).

triage_unknowns

Triage a batch of uncertainties into answerable, verifiable, or neither

Triage everything you are uncertain about in one call. Free, instant, read-only, no side effects — call liberally during planning. Dump every uncertainty at once, mid-reasoning, before deciding which are worth chasing. Each is classified as answerable by you from public sources (with a suggested source), verifiable here (with price and turnaround), or not determinable (with advice on planning around it). Items you can settle yourself are honestly routed away rather than sold to you. Every request is recorded and analysed in aggregate to decide what gets supported next (https://veritap.dev/terms).

65% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
