42 tools. 6 can modify or destroy data without limits.
1 destructive tool with no built-in limits. Policy required.
Last updated:
Destructive tools (delete_watch) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (create_digest_watch, create_leaderboard_rank_watch, create_price_watch) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (whats_new) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
delete_watch:
rules:
- action: deny Destructive tools should never be available to autonomous agents without human approval.
create_digest_watch:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
benchmark_series:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The TensorFeed server exposes 1 destructive tools including delete_watch. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The TensorFeed server has 4 write tools including create_digest_watch, create_leaderboard_rank_watch, create_price_watch. 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.
42 tools across 4 categories: Destructive, Execute, Read, Write. 36 are read-only. 6 can modify, create, or delete data.
One line change. Instead of running the TensorFeed server directly, prefix it with Intercept: intercept -c tensorfeed.yaml -- npx -y @@tensorfeed/mcp-server. Download a pre-built policy from policylayer.com/policies/tensorfeed and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
