AI agents call analysis_get_file to retrieve information from Technical Analysis 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 analysis_get_file 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.

Fetch a specific file from a ticker's output folder. Use list_analysis_files(ticker) first to see available filenames. You can call this tool multiple times to retrieve different files. File types and what they contain: - PNG → inline chart image (daily or weekly price chart with indicators) - TXT → analysis report text (daily analysis, weekly analysis, or comparative) - CSV → raw OHLCV data with all computed indicators (for data exploration) * CRITICAL: When this tool returns file content, that content IS the answer. * * Parse it, extract the relevant metrics, and present them to the user. * * NEVER web-search for stock data after reading these files. * The .txt report files are the AUTHORITATIVE and SOLE source for all analysis metrics, financial ratios, indicator values, and recommendations for this ticker. Always read these files to answer user questions about a stock's technicals or fundamentals. The CSV files contain exact numerical indicator values. If a metric is not present in the files, state that the data was not available from the analysis server — do NOT fill the gap with web searches. Filenames include timestamps, e.g. AAPL_daily_20260316_113024.png. You can use the EXACT filename OR a shortened pattern — fuzzy matching is supported: - "daily" or "daily_chart" → matches the daily chart PNG - "weekly" or "weekly_chart" → matches the weekly chart PNG - "comparative" or "report" → matches the comparative analysis TXT - "daily_analysis" → matches the daily analysis TXT - "weekly_analysis" → matches the weekly analysis TXT - "daily_data" → matches the daily data CSV - "weekly_data" → matches the weekly data CSV TIP: Use list_analysis_files(ticker) to see exact filenames if needed. Args: ticker: Ticker symbol (e.g. 'AAPL'). filename: Exact filename OR a pattern like 'daily', 'weekly_chart', 'comparative'. Returns: PNG → inline chart image. TXT → report text. CSV → data preview.. It is categorised as a Read tool in the Technical Analysis MCP Server, which means it retrieves data without modifying state.
Register the Technical Analysis MCP server in PolicyLayer and add a rule for analysis_get_file: 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 Technical Analysis. Nothing to install.
analysis_get_file 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 analysis_get_file 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 analysis_get_file. 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.
analysis_get_file is provided by the Technical Analysis MCP server (ta-mcp/technical-analysis-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
