Bulk/mass operation — affects multiple targets
Part of the ContrastAPI MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call ip_lookup to retrieve information from ContrastAPI 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 ip_lookup 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.

Query comprehensive IP intelligence: reverse DNS, ASN + holder name + country inline (RIPE Stat, Phase 1), open ports, hostnames, vulnerabilities (Shodan InternetDB enriched with severity + cvss_v3 from local cve.db — Phase 2 v1.16.0 BREAKING; vulns is now list[VulnInfo] {cve_id, severity, cvss_v3} dicts, pre-1.16 it was list[str] of CVE IDs; unknown CVEs emit severity='UNKNOWN' / cvss_v3=null — do NOT infer benign), cloud provider, Tor exit status, and reputation. cloud_provider uses two-tier detection: published cloud CIDR ranges (AWS/GCP/Cloudflare) first, then an ASN-to-provider fallback map for anycast/public-service IPs outside published ranges (e.g. 8.8.8.8 → AS15169 → 'Google'). Reputation: FireHOL level1 blocklist on Free tier; +AbuseIPDB + Shodan on Pro (Phase 4). Use for IP investigation; for orchestrated IP+reputation use threat_report. Response is null-explicit: every field is always present (cloud_provider=null when neither tier matches; tor_exit=false when not listed or upstream fetch failed — check verdict.sources_unavailable to disambiguate fetch failure from genuine absence). Response carries next_calls (conditional) — asn_lookup when ASN is populated, ioc_lookup when reputation is FireHOL-listed or AbuseIPDB confidence>50, threat_report on Pro tier for orchestrated profile. Free: 30/hr, Pro: 500/hr. Returns {ip, ptr, geo, asn, asn_name, country, ports, hostnames, vulns, cloud_provider, tor_exit, reputation, risk_score, verdict, next_calls}.. It is categorised as a Read tool in the ContrastAPI MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for ip_lookup. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the ContrastAPI MCP server.
ip_lookup 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 ip_lookup rule in your Intercept 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 Intercept policy for ip_lookup. 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.
ip_lookup is provided by the ContrastAPI MCP server (contrastcyber/contrastapi). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
