Part of the Openinsider MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call get_quote 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 get_quote 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.

Live stock quote for a ticker, sourced from Yahoo Finance. Returns one Quote object: current price, previous close, 52-week range, regular-session volume + 3-month average volume, market cap, beta, trailing/forward P/E, dividend yield, ex-dividend date, next earnings date, currency, exchange, and ISO timestamp. Cache TTL is 60s. Use when: - User asks "what's TICKER trading at" or "TICKER price" - Cross-referencing valuation (P/E, market cap) with insider activity or short interest - Checking the next earnings date or current dividend yield Caveats: - dividendYield is a decimal, not a percent (0.0042 = 0.42%) — matches Yahoo's wire format - ETFs typically have null trailingPE / forwardPE; many still have a dividendYield - Non-dividend payers have null dividendYield / exDividendDate - timestamp is the time of the most recent regular-session price; on weekends and holidays it points to the last trading session, not "now" - Sourced by scraping the structured JSON Yahoo embeds in its public quote page; throws a clean error if Yahoo's response shape changes or the ticker isn't found.. 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 get_quote. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Openinsider MCP server.
get_quote 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 get_quote 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 get_quote. 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.
get_quote 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.
