AI agents call search_available_datasets to retrieve information from Livedatalink 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 search_available_datasets 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.

Your guide to LiveDataLink's entire data catalog. Call this FIRST when you're unsure which tool to use, or when the user asks about data availability. LiveDataLink has 177 tools across 50+ data domains: finance (stocks, options), crypto, transportation/FMCSA carriers, property records, weather/air quality, vehicle VIN/recalls, package tracking, local business search, sanctions screening (OFAC SDN, EU, UN, BIS), FEMA disasters and flood data, federal courts (CourtListener), cybersecurity (CVE/CWE/EPSS/CISA KEV), US college metrics (IPEDS), EIA energy data (gasoline, natural gas, electricity, oil supply, renewables), FRED Federal Reserve macroeconomic series (GDP, CPI, fed funds, unemployment, yields), SEC EDGAR filings (10-K, 10-Q, 8-K, insider transactions), and NREL renewable energy (PVWatts solar, utility rates, EV charging stations), US Census demographics, EPA environmental compliance, FEC campaign finance, USPTO patents, IRS nonprofits (Form 990/EO BMF), US caselaw, public-domain books (full-text search), open-access scholarly papers (OpenAlex catalog + arXiv/PMC full-text search), and federal regulations (Federal Register rules/notices + the Code of Federal Regulations). New domains ship weekly based on which queries customers actually run. Returns exact tool names for matched domains AND logs every search to a roadmap database. High-frequency unmet queries jump the build queue. Use this freely; it costs no credits. Call for: 'what data do you have?', 'can you look up X?', 'do you have Y data?', 'what tools are available?', or any data coverage question.. It is categorised as a Read tool in the Livedatalink MCP Server, which means it retrieves data without modifying state.
Register the Livedatalink MCP server in PolicyLayer and add a rule for search_available_datasets: 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 Livedatalink. Nothing to install.
search_available_datasets 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 search_available_datasets 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 search_available_datasets. 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.
search_available_datasets is provided by the Livedatalink MCP server (https://livedatalink.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
