Choosing between two AI agents for a task? Scores both and shows which is stronger in each category — schema quality, reliability, docs, ecosystem, maintenance. Helps pick the more trustworthy option based on data.
AI agents call compare_agents to retrieve information from Agent Seo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
url_a | string | — | First agent URL to compare |
url_b | string | — | Second agent URL to compare |
Parameters from the server's own tool schema.
Even though compare_agents 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.
Documented attack patterns abuse exactly the kind of access compare_agents gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Agent Seo, and nothing reaches the server without passing your rules. This is the rule we recommend for compare_agents:
{
"version": "1",
"default": "deny",
"tools": {
"compare_agents": {}
}
}compare_agents is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Choosing between two AI agents for a task? Scores both and shows which is stronger in each category — schema quality, reliability, docs, ecosystem, maintenance. Helps pick the more trustworthy option based on data. It is categorised as a Read tool in the Agent Seo MCP Server, which means it retrieves data without modifying state.
compare_agents accepts 2 parameters: url_a, url_b. The full parameter table on this page comes from the server's own tool schema.
Register the Agent Seo MCP server in PolicyLayer and add a rule for compare_agents: 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 Agent Seo. Nothing to install.
compare_agents 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 compare_agents 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 compare_agents. 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.
compare_agents is provided by the Agent Seo MCP server (web3signals/agent-seo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
