MOST DANGEROUS TOOLS

High Risk

The most dangerous Via tools

Write · Medium via_memory_add This tool creates or modifies data in a shared memory store, which is reversible (facts can be updated or overwritten). Write · Low via_task_add This tool creates/adds data (a task) to a shared task board, which is reversible (tasks can be deleted or modified). Write · Low via_log This tool writes/appends data to a log. Write · Low via_task_done This tool updates the status of an existing task to 'done', which is a reversible state change (the task record still exists and could theoretically be re-opened).

4 of Via's 8 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Via

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

Rate limit write operations

{
  "via_log": {
    "limits": [
      {
        "counter": "via_log_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "via_context": {
    "limits": [
      {
        "counter": "via_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 Via — 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 Via

How do I prevent bulk modifications through Via? +

The Via server has 4 write tools including via_log, via_task_done, via_memory_add. 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 Via.

How many tools does the Via MCP server expose? +

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

How do I enforce a policy on Via? +

Register the Via 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 Via tool call.

Deterministic rules across all 8 Via tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
