Search for government grants based on keywords
AI agents call search-grants to retrieve information from Grants Search 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 and filters data from a grants database based on user-provided keywords. It performs a search operation that returns matching results without creating, modifying, deleting, or executing any external actions. The blast radius of misuse is minimal — an agent might return irrelevant or excessive results, but cannot cause data loss, unauthorized changes, or financial harm.
From the tool's definition Tool name is 'search-grants' and description states it 'Search[es] for government grants based on keywords' — a pure query operation with no side effects.
Documented attack patterns abuse exactly the kind of access search-grants gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Grants Search MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search-grants:
{
"version": "1",
"default": "deny",
"tools": {
"search-grants": {}
}
}search-grants is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for government grants based on keywords. It is categorised as a Read tool in the Grants Search MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Grants Search MCP Server MCP server in PolicyLayer and add a rule for search-grants: 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 Grants Search MCP Server. Nothing to install.
search-grants 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-grants 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-grants. 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-grants is provided by the Grants Search MCP Server MCP server (tar-ive/grants-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Grants Search MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
