Even read-only tools carry cost. An agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up bills.
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Server Fetch TypeScript, and nothing reaches the server without passing your rules. These are the rules we recommend:
{
"get_markdown": {
"limits": [
{
"counter": "get_markdown_per_minute",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
} Controls API costs and prevents retry loops from exhausting upstream rate limits.
Instant setup, no code required.
The MCP Server Fetch TypeScript server is primarily read-only with 4 read tools. While it cannot modify data, an agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up costs. Rate limiting is still recommended.
4 tools across 1 categories: Read. 4 are read-only. 0 can modify, create, or delete data.
Register the MCP Server Fetch TypeScript MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
Deterministic rules across all 4 MCP Server Fetch TypeScript tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
Instant setup, no code required.
