InferenceView MCP
This server lets MCP clients verify x402 resources before payment and fact-check claims before acting on them, while keeping the wallet key on the local machine.
verify_transaction— provide an x402 resource URL to get risk, recommendation, and evidence before paying it.factcheck— submit a claim to get a verdict (supported/refuted/mixed/unverifiable), confidence, primary sources, freshness, contradictions, and evidence.Fact-check depth can be set to
quick,standard, ordeep, with optional context about the claim (URL, person, company, product, data point).The server pays the remote InferenceView API over x402; the wallet key is never sent to InferenceView.
Useful for safely evaluating unknown MCP/x402 resources and verifying claims before acting on them.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@InferenceView MCP Verify this x402 transaction before I pay for it."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
InferenceView MCP
Use InferenceView from any Model Context Protocol client to check an x402/MCP resource before paying it or to fact-check a claim before acting on it.
The local MCP process keeps your wallet key on your machine and pays the remote InferenceView API over x402. The key is never sent to InferenceView.
Tools
verify_transaction— returns risk, recommendation and evidence about an x402 resource before payment. Current price: $0.01 USDC on Base.factcheck— returns a supported/refuted/mixed/unverifiable verdict with sources. Current tiers: $0.05, $0.10 and $0.25 USDC on Base.
Always trust the live x402 challenge over prices copied into documentation.

Scored across 2 tools
The two tools address entirely different verification domains: one assesses transaction risk for x402/MCP resources, while the other evaluates the veracity of factual claims. There is no overlap in inputs, operations, or outputs, making misselection impossible.
Both tool names use lowercase and avoid special characters, but verify_transaction follows a clear verb_noun pattern while factcheck is a single compound word. This minor stylistic mismatch is easy to read and does not hinder predictability.
With only two tools, the server feels somewhat thin. However, each tool covers a distinct, substantive verification use case, and the narrow focus justifies the small count, making it acceptable if not ideal.
The server's implied domain is pre-action verification, and the two tools cover the primary needs: verifying transactions and verifying facts. No critical gaps are apparent within this scope, though a broader verification suite might include other resource types.
