3 destructive tools with no built-in limits. Policy required.

Financial operations (transfer_native, transfer_private_erc20, transfer_private_erc721) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Write operations (approve_erc20_spender, approve_private_erc721, call_contract_function) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (compile_and_deploy_contract, compile_contract, deploy_private_erc20_contract) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
Intercept sits between your agent and COTI MCP Server. 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 @davibauer/coti-mcp transfer_native:
rules:
- action: deny Financial tools should be explicitly enabled per use case, not open by default.
approve_erc20_spender:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
decode_event_data:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The COTI MCP Server server exposes 3 financial tools including transfer_native, transfer_private_erc20, transfer_private_erc721. 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.
The COTI MCP Server server has 9 write tools including approve_erc20_spender, approve_private_erc721, call_contract_function. 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.
44 tools across 4 categories: Execute, Financial, Read, Write. 27 are read-only. 17 can modify, create, or delete data.
One line change. Instead of running the COTI MCP Server server directly, prefix it with Intercept: intercept -c davibauer-coti-mcp.yaml -- npx -y @davibauer/coti-mcp. Download a pre-built policy from policylayer.com/policies/davibauer-coti-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.
