32 tools. 17 can modify or destroy data without limits.
2 destructive tools with no built-in limits. Policy required.
Last updated:
Financial operations (linear_transferIssue) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Destructive tools (linear_removeIssueLabel) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (linear_addIssueLabel, linear_addIssueToCycle, linear_addIssueToProject) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
linear_transferIssue:
rules:
- action: deny Financial tools should be explicitly enabled per use case, not open by default.
linear_removeIssueLabel:
rules:
- action: deny Destructive tools should never be available to autonomous agents without human approval.
linear_addIssueLabel:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
linear_getActiveCycle:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The Linear MCP Server server exposes 1 financial tools including linear_transferIssue. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. Intercept lets you block financial tools by default or set per-tool rate limits.
Yes. The Linear MCP Server server exposes 1 destructive tools including linear_removeIssueLabel. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The Linear MCP Server server has 15 write tools including linear_addIssueLabel, linear_addIssueToCycle, linear_addIssueToProject. 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.
32 tools across 4 categories: Destructive, Financial, Read, Write. 15 are read-only. 17 can modify, create, or delete data.
One line change. Instead of running the Linear MCP Server server directly, prefix it with Intercept: intercept -c emmett-deen-linear-mcp-server.yaml -- npx -y @emmett-deen/linear-mcp-server. Download a pre-built policy from policylayer.com/policies/emmett-deen-linear-mcp-server and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
