6 tools. 2 can modify or destroy data without limits.
2 write tools that can modify data. Rate limits recommended.
Last updated:
Write operations (create-issue, update-issue) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
create-issue:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
get-issue:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
The Plane MCP Server server has 2 write tools including create-issue, update-issue. 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.
6 tools across 2 categories: Read, Write. 4 are read-only. 2 can modify, create, or delete data.
One line change. Instead of running the Plane MCP Server server directly, prefix it with Intercept: intercept -c kelvin6365-plane-mcp-server.yaml -- npx -y @kelvin6365/plane-mcp-server. Download a pre-built policy from policylayer.com/policies/kelvin6365-plane-mcp-server and adjust the limits to match your use case.
