12 tools. 11 can modify or destroy data without limits.
11 write tools that can modify data. Rate limits recommended.
Last updated:
Write operations (arbiter_lock_acquire, arbiter_lock_release, blockwire_feed) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (arbiter_election_run) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
Intercept sits between your agent and Echorift. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.
npx -y @policylayer/intercept scan -- npx -y @echorift/mcp arbiter_lock_acquire:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
arbiter_leader_get:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
The Echorift server has 10 write tools including arbiter_lock_acquire, arbiter_lock_release, blockwire_feed. 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.
12 tools across 3 categories: Execute, Read, Write. 1 are read-only. 11 can modify, create, or delete data.
One line change. Instead of running the Echorift server directly, prefix it with Intercept: intercept -c io-github-aaronvick-echorift-mcp.yaml -- npx -y @@echorift/mcp. Download a pre-built policy from policylayer.com/policies/io-github-aaronvick-echorift-mcp 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.
