AI agents call analysis_list_files 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_list_files 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.

Browse stored analysis outputs on the server. Call this FIRST before get_file to discover what files are available. This is the recommended starting point when the user asks about a specific ticker's analysis — check what's already cached before running a new analysis. Each analysis produces 7 files per ticker: - 2 chart images (daily + weekly PNG) - 3 analysis reports (daily, weekly, comparative TXT) - 2 data files (daily + weekly CSV with OHLCV + indicators) Cached OHLCV files are stored in cache/ohlcv/{market}/ and auto-cleaned daily at market-specific times. Output result files in output/ are auto-cleaned after 7 days. Args: ticker: Optional. If omitted, lists all tickers that have been analyzed. If provided, lists all available files for that ticker with sizes. Returns: Without ticker: summary of all ticker folders. With ticker: detailed file listing with types and sizes.. 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_list_files: 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_list_files 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_list_files 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_list_files. 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_list_files 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.
