Token news. Params: symbols (comma), chain, start, end, limit, cursor, sources.
AI agents call elfa_token_news to retrieve information from CG Alpha MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves news/information about tokens filtered by symbol, chain, time range, and sources. It is a read-only query operation with no side effects, modifications, or destructive actions. The parameters (symbols, chain, start, end, limit, cursor, sources) are all filtering/pagination parameters typical of a data retrieval API.
From the tool's definition Token news. Params: symbols (comma), chain, start, end, limit, cursor, sources.

Register the CG Alpha MCP server in PolicyLayer and add a rule for elfa_token_news: 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 CG Alpha MCP. Nothing to install.
elfa_token_news 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 elfa_token_news 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 elfa_token_news. 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.
elfa_token_news is provided by the CG Alpha MCP server (jcf0/cg-alpha-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
