11 of LDK MCP Server's 23 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.
PolicyLayer is an MCP gateway — it sits between your AI agents and LDK MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:
{
"ldk_pay_invoice": {
"deny_if": [
{
"conditions": [],
"on_deny": "Requires human approval."
}
]
}
} Financial tools should be explicitly enabled per use case, not open by default.
{
"ldk_close_channel": {
"deny_if": [
{
"conditions": [],
"on_deny": "Blocked by default. Requires approval."
}
]
}
} Destructive tools should never be available to autonomous agents without human approval.
{
"ldk_backup_state": {
"limits": [
{
"counter": "ldk_backup_state_per_hour",
"window": "hour",
"max": 30,
"scope": "grant"
}
]
}
} Prevents bulk unintended modifications from agents caught in loops.
{
"ldk_chain_sync": {
"limits": [
{
"counter": "ldk_chain_sync_per_minute",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
} Controls API costs and prevents retry loops from exhausting upstream rate limits.
Instant setup, no code required.
Other MCP servers with similar tools — same risk classification, starter policies for each.
Yes. The LDK MCP Server server exposes 1 financial tools including ldk_pay_invoice. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. PolicyLayer lets you block financial tools by default, require human approval, or set per-tool rate limits — enforced on every call.
Yes. The LDK MCP Server server exposes 1 destructive tools including ldk_close_channel. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.
The LDK MCP Server server has 3 write tools including ldk_backup_state, ldk_create_channel, ldk_generate_invoice. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach LDK MCP Server.
23 tools across 3 categories: Financial, Read, Write. 12 are read-only. 11 can modify, create, or delete data.
Register the LDK MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
Deterministic rules across all 23 LDK MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
