MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Acheron tools

Destructive · High bridge_delete_context This tool destroys stored data without recovery options. Write · Medium bridge_save_context This tool creates or modifies records in a local SQLite database to store context across sessions.

2 of Acheron's 6 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Acheron

PolicyLayer is an MCP gateway — it sits between your AI agents and Acheron, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations

{
  "bridge_delete_context": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "bridge_save_context": {
    "limits": [
      {
        "counter": "bridge_save_context_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "bridge_get_context": {
    "limits": [
      {
        "counter": "bridge_get_context_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Acheron — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Acheron

Can an AI agent delete data through the Acheron MCP server? +

Yes. The Acheron server exposes 1 destructive tools including bridge_delete_context. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Acheron? +

The Acheron server has 1 write tools including bridge_save_context. 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 Acheron.

How many tools does the Acheron MCP server expose? +

6 tools across 3 categories: Destructive, Read, Write. 4 are read-only. 2 can modify, create, or delete data.

How do I enforce a policy on Acheron? +

Register the Acheron 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.

Enforce policy on every Acheron tool call.

Deterministic rules across all 6 Acheron tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
