get_cci
AI agents call get_cci to retrieve information from AlphaVantage MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves pre-calculated technical indicator data (CCI) from the AlphaVantage API. It performs a read-only query with no side effects, data modification, code execution, or financial transactions. While the server provides financial data, this particular tool only queries and returns technical indicator values without any capacity to execute trades, modify accounts, or alter data.
From the tool's definition Tool name 'get_cci' follows the naming pattern of sibling tools (get_ad, get_adosc, get_adx, etc.) which are all technical indicators. CCI (Commodity Channel Index) is a standard technical indicator for financial analysis.

get_cci. It is categorised as a Read tool in the AlphaVantage MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AlphaVantage MCP Server MCP server in PolicyLayer and add a rule for get_cci: 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 AlphaVantage MCP Server. Nothing to install.
get_cci 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_cci 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 get_cci. 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_cci is provided by the AlphaVantage MCP Server MCP server (lifejwang11/alphavantage-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
