Part of the Openinsider MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call short_interest to retrieve information from Openinsider 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 short_interest 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.

FINRA bi-monthly short-interest snapshots for a ticker, with delta vs prior period. Bi-monthly cadence: settlement on 15th and last business day, published ~7 business days later — the most recent snapshot may lag spot price by 1-2 weeks. Returns shares short, % of float, days-to-cover, and change vs prior period. Use when: - User asks 'is TICKER heavily shorted' or 'is short interest rising' - Researching squeeze setups (high SI + low float + threshold listing) or contrarian entries - Cross-referencing with insider buying — Wang-Lai (2023) found insider-buy + SI-spike combo predictive Important: for daily short FLOW (not standing position), use `daily_short_volume` instead — different measurements. pctOfFloat is null when SEC XBRL doesn't report shares outstanding under either dei:EntityCommonStockSharesOutstanding or us-gaap:CommonStockSharesOutstanding (uncommon; some foreign issuers and ADRs).. It is categorised as a Read tool in the Openinsider MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for short_interest. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Openinsider MCP server.
short_interest 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 short_interest 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 short_interest. 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.
short_interest is provided by the Openinsider MCP server (openinsider-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
