AI agents call search-emission-factors to retrieve information from Climatiq MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches or queries emission factor data from the Climatiq API. It retrieves information to support carbon emissions calculations but does not create, modify, delete, or execute operations. The search functionality is a read-only operation with no side effects on the underlying data or external systems.
From the tool's definition Tool name is 'search-emission-factors' and description states 'Search Climatiq', which indicates data retrieval without modification. Sibling tools like 'cloud-computing-emission' and 'electricity-emission' similarly appear to query emission data.
Documented attack patterns abuse exactly the kind of access search-emission-factors gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Climatiq MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search-emission-factors:
{
"version": "1",
"default": "deny",
"tools": {
"search-emission-factors": {}
}
}search-emission-factors is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search Climatiq. It is categorised as a Read tool in the Climatiq MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Climatiq MCP Server MCP server in PolicyLayer and add a rule for search-emission-factors: 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 Climatiq MCP Server. Nothing to install.
search-emission-factors 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 search-emission-factors 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 search-emission-factors. 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.
search-emission-factors is provided by the Climatiq MCP Server MCP server (jagan-shanmugam/climatiq-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Climatiq MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
