28 tools. 8 can modify or destroy data without limits.
2 destructive tools with no built-in limits. Policy required.
Last updated:
Destructive tools (cancel_wager, unfavourite_bet) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (create_bet, favourite_bet, initiate_vote) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Intercept sits between your agent and Poll. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.

rules:
- action: deny Destructive tools should never be available to autonomous agents without human approval.
create_bet:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.

- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The Poll server exposes 2 destructive tools including cancel_wager, unfavourite_bet. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The Poll server has 6 write tools including create_bet, favourite_bet, initiate_vote. 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.
28 tools across 3 categories: Destructive, Read, Write. 20 are read-only. 8 can modify, create, or delete data.
One line change. Instead of running the Poll server directly, prefix it with Intercept: intercept -c poll.yaml -- npx -y @@solworks/poll-mcp. Download a pre-built policy from policylayer.com/policies/poll and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
Set budgets, approvals, and hard limits across MCP servers.
