Compose N (cell, band, tslot?) triples into ONE signed envelope.

AI agents use emem_memory_bundle to create or modify resources in emem — Earth memory protocol. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call emem_memory_bundle repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach emem — Earth memory protocol.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access emem_memory_bundle gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Compose N (cell, band, tslot?) triples into ONE signed envelope. Each triple runs through the standard auto-materialize recall path; the resulting fact_cids are bundled into a content-addressed envelope and the responder signs over the full receipt. The composed bundle_token is memb:<bundle_cid> — a single rebindable string that cites the whole set. When to use: Call when the agent wants to cite multiple (place, band, vintage) facts as one handle. The bundle stays verifiable offline via /v1/verify_receipt (the receipt covers all cited fact_cids and cells). Use this instead of N separate emem_memory_token composers when the citation is conceptually one thing (e.g. "the EUDR-relevant baseline for these 8 plots at 2020-12-31").. It is categorised as a Write tool in the emem — Earth memory protocol MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the emem — Earth memory protocol MCP server in PolicyLayer and add a rule for emem_memory_bundle: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches emem — Earth memory protocol. Nothing to install.
emem_memory_bundle is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the emem_memory_bundle rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for emem_memory_bundle. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
emem_memory_bundle is provided by the emem — Earth memory protocol MCP server (oci:ghcr.io/vortx-ai/emem:latest). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
