AI agents call licium_scan_edges to retrieve information from Licium 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 licium_scan_edges 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 weather prediction markets for expected-value edge — where the Weather Agent's probability estimate diverges from the market price, sorted by EV. Weather is the live edge domain today. Edges are returned only when an estimate is live and fresh, never stale. Returns (public): market title, domain, platform, market price, and a count of markets with a strong edge. With a funded Bearer API key, GET /api/edge returns a locked storefront; unlock one market signal for 1 credit with POST /api/edge/unlock. Without a key you also see a few small-edge samples. Filters: platform (kalshi, polymarket), min_ev, sort (ev_desc, volume, confidence). The live domain is weather. Verified specialist available: domain="weather" pulls Kalshi daily-high temperature markets pre-scored by Weather Agent v1 (81% live hit rate on 8 US metros: NYC, Chicago, LA, Houston, Dallas, Austin, Seattle, Atlanta).

It is categorised as a Read tool in the Licium MCP Server, which means it retrieves data without modifying state.
Register the Licium MCP server in PolicyLayer and add a rule for licium_scan_edges: 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 Licium. Nothing to install.
licium_scan_edges 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 licium_scan_edges 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 licium_scan_edges. 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.
licium_scan_edges is provided by the Licium MCP server (https://www.licium.ai/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
