How this service works

Machine-payable service intelligence for discovering, verifying, and monitoring identity, risk, authorization, execution-preflight, and evidence APIs before autonomous agents spend.

Output

Returns a JSON object with a risk_level (e.g. 'low', 'medium', 'high'), a numeric risk_score, an array of assessment flags describing specific concerns found, the product name ('nomos-mcp-trust-preflight'), and the network identifier (EIP-155 Base chain). Flags array is empty when no issues are detected.

Example use cases

Pre-payment safety check for MCP tool

“Before my agent pays to call that new MCP data tool, can you run a trust preflight on it? The publisher is 'datatools-inc', the repo is 'github.com/datatools-inc/mcp-scraper', it requires network access to external-data.io, and it has lifecycle install scripts I'm worried about.”

Vetting agent plugin with broad filesystem access

“I want to install an MCP plugin that claims it needs full filesystem read/write access and stores credentials locally — can you assess its risk level before I authorize anything? The publisher is 'unknown-dev', repo is 'github.com/unknown-dev/mcp-agent', and maintenance status is unclear.”

Clearing a low-risk internal tool for agent use

“We built our own internal MCP server for the team — publisher is 'our-company', repo is 'github.com/our-company/internal-mcp', it only calls our own API endpoints and has no install scripts. Can you run a trust preflight to confirm it's low risk before we let agents use it autonomously?”

Technical details

Endpoint

POSThttps://base-agent-preflight.bytoken2023.workers.dev/x402/v1/mcp/trust-preflight?utm_source=zero.xyz

When to prefer

Use this endpoint when an autonomous agent needs to vet an MCP server or tool package before executing it or authorizing payment — especially when the publisher is unknown, install scripts are present, broad permissions are declared, or external network destinations are involved. Prefer this over generic security scanners because it is specifically designed for the MCP/agent tool ecosystem and produces structured risk scores and flags that agents can act on programmatically.

Side effects

Missing or malformed input fields may result in incomplete risk assessment
Unknown publishers or private repositories may reduce assessment accuracy
High-traffic periods may increase response latency slightly above typical
Payment failure via x402 protocol will block access before assessment is returned
Ambiguous or contradictory permission declarations may produce inconclusive flags
