MOST DANGEROUS TOOLS

High Risk

The most dangerous Project Tessera tools

Execute · High migrate_data Data migrations typically execute a process that restructures, transforms, or moves data between schemas or storage locations. Write · Low digest_conversation This tool reads conversation data and writes it to persistent storage (the indexed vector store), but does not delete, execute code, move money, or perform irreversible operations. Write · Medium import_conversations This tool adds or modifies data in the workspace memory system (conversations and extracted knowledge). Write · Medium import_from_ai The tool imports external data into the local memory system, which constitutes creation or modification of stored data.

9 of Project Tessera's 43 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Project Tessera

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

Rate limit write operations

{
  "organize_files": {
    "limits": [
      {
        "counter": "organize_files_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "context_window": {
    "limits": [
      {
        "counter": "context_window_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 Project Tessera — 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 Project Tessera

How do I prevent bulk modifications through Project Tessera? +

The Project Tessera server has 8 write tools including organize_files, sync_documents, toggle_auto_learn. 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 Project Tessera.

How many tools does the Project Tessera MCP server expose? +

43 tools across 3 categories: Execute, Read, Write. 34 are read-only. 9 can modify, create, or delete data.

How do I enforce a policy on Project Tessera? +

Register the Project Tessera 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 Project Tessera tool call.

Deterministic rules across all 43 Project Tessera tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
