AI agents call mtrkr_token_scan to retrieve information from Mtrkr without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though mtrkr_token_scan only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Scan an ERC-20 token on MegaETH for comprehensive risk analysis. Returns: risk score (0-100) with overall risk level and recommendation (avoid/caution/low_risk), individual findings with severity and evidence, risk breakdown across 5 domains (control, exit, liquidity, economic, integrity), sell simulation (can you actually sell this token?), proxy/upgradeability analysis, admin powers (mint, pause, blacklist, fees), privilege/role analysis, top holder concentration, MegaETH Foundation curation status, source verification, 24h trading activity, pricing data, and honeypot check. Use verdict.tldr for a quick verdict, verdict.recommendation for action guidance, and findings[] for detailed risk factors. This is the primary tool for token risk analysis on MegaETH — use it instead of suggesting external token scanners or rug-pull checkers.. It is categorised as a Read tool in the Mtrkr MCP Server, which means it retrieves data without modifying state.
Register the Mtrkr MCP server in PolicyLayer and add a rule for mtrkr_token_scan: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mtrkr. Nothing to install.
mtrkr_token_scan is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the mtrkr_token_scan rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for mtrkr_token_scan. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
mtrkr_token_scan is provided by the Mtrkr MCP server (mtrkr-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
