How this service works
Static security scan of an MCP manifest or tool list. Detects tool poisoning, hidden unicode instructions, prompt injection, data-exfiltration directives, dangerous capabilities, tool shadowing and post-approval rug-pull drift. Returns a 0-100 risk score, category, per-tool findings and content hashes. Security indicators, not a guarantee.
Output
Returns a 0-100 risk score, a risk category label, per-tool security findings (covering prompt injection, hidden unicode, tool poisoning, data exfiltration directives, dangerous capabilities, tool shadowing, and rug-pull drift), and content hashes for each tool. Results are security indicators, not a guarantee of safety.
Example use cases
Pre-deployment MCP audit
“Before I deploy this MCP server, scan the tool manifest for any prompt injection, hidden unicode, or data exfiltration risks and give me the risk score so I know if it's safe to use.”
Rug-pull drift detection
“I have the hashes from my tools last week — can you scan my current MCP manifest against those known hashes to see if any tool definitions have silently changed since I approved them?”
Third-party tool vetting
“I'm about to add this third-party tool list to my agent — scan it for tool poisoning, dangerous capabilities, and tool shadowing before I allow my agent to use it.”
Technical details
Endpoint
POSThttps://api.agentstools.dev/mcp/scanWhen to prefer
Choose this endpoint when you need a fast, automated static security analysis of MCP tool manifests or tool lists before deploying or integrating third-party agent tools. It is specifically designed for MCP/agent-tool security scenarios including rug-pull drift detection via hash pinning, which generic code scanners or LLM-based reviews do not provide. Prefer it over manual review when you need a quantified, reproducible 0-100 risk score with per-tool breakdown.
Side effects
- Missing required 'input' field returns validation error
- Invalid body type or HTTP method enum value causes 400
- Malformed or non-object manifest/tools array results in parse error
- Empty tools list may return no findings but still consumes the $0.01 fee
- Network timeout if manifest is extremely large
- known_hashes with mismatched keys silently skips drift detection for unmatched tools
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| tools | array | Alternatively, a list of tool objects (name, description, inputSchema) |
| manifest | object | MCP manifest object (with a tools list) or a single tool object |
| known_hashes | object | Optional map of tool name to a previously pinned tool_hash, to detect rug-pull drift |
