What coingecko_chain does on Crawlora
AI agents call coingecko_chain to retrieve information from Crawlora without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
id | string | Yes | CoinGecko chain id such as ethereum |
limit | integer | — | Rows per section to return, default 20, max 100 |
vs_currency | string | — | Quote currency |
Parameters from the server's own tool schema.
Why coingecko_chain is rated Low
Even though coingecko_chain only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs coingecko_chain safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Crawlora, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For coingecko_chain, this is the rule to start with:
coingecko_chain is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Crawlora, apply this rule, and every coingecko_chain call is checked against it from then on.

CoinGecko chain detail. Returns normalized sections from a CoinGecko public chain detail page. Sections are omitted when not present. This endpoint supports the documented vs_currency enum. It is categorised as a Read tool in the Crawlora MCP Server, which means it retrieves data without modifying state.
coingecko_chain accepts 3 parameters: id, limit, vs_currency. Required: id. The full parameter table on this page comes from the server's own tool schema.
Register the Crawlora MCP server in PolicyLayer and add a rule for coingecko_chain: 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 Crawlora. Nothing to install.
coingecko_chain 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 coingecko_chain 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 coingecko_chain. 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.
coingecko_chain is provided by the Crawlora MCP server (crawlora-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
