Read (11) Write / Execute (18) Destructive / Financial (0)

Write operations (browser_click, browser_close_tab, browser_fill) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.

Execute tools (browser_execute_script, browser_hover, browser_navigate) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.

One command. Full control.

Intercept sits between your agent and Browser. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.

Rate limit write operations
browser_click:
  rules:
    - rate_limit: 30/hour

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
browser_ask_user:
  rules:
    - rate_limit: 60/minute

Controls API costs and prevents retry loops from exhausting upstream rate limits.

How do I prevent bulk modifications through Browser? +

The Browser server has 13 write tools including browser_click, browser_close_tab, browser_fill. Set rate limits in your policy file -- for example, rate_limit: 10/hour prevents an agent from making more than 10 modifications per hour. Intercept enforces this at the transport layer.

How many tools does the Browser MCP server expose? +

29 tools across 3 categories: Execute, Read, Write. 11 are read-only. 18 can modify, create, or delete data.

How do I add Intercept to my Browser setup? +

One line change. Instead of running the Browser server directly, prefix it with Intercept: intercept -c io-github-agent360dk-browser-mcp.yaml -- npx -y @@agent360/browser-mcp. Download a pre-built policy from policylayer.com/policies/io-github-agent360dk-browser-mcp and adjust the limits to match your use case.
