research_source_list

List the sources attached to a research project (id, kind, name, uri, bytes, chunk_count, status, added_at). All local to the user.

What research_source_list does on Celiums Memory

AI agents call research_source_list to retrieve information from Celiums Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Low Risk

Why research_source_list needs a policy

This tool retrieves and displays metadata about research project sources without creating, modifying, deleting, or executing any operations. It is scoped to user-local data, presenting no destructive, financial, or code execution risks. The low severity reflects that source listing poses minimal security risk—it is purely informational querying of existing project attachments.

From the tool's definition Tool description explicitly states it 'List the sources' with retrieval of metadata fields (id, kind, name, uri, bytes, chunk_count, status, added_at).

How to control research_source_list

PolicyLayer is an MCP gateway — it sits between your AI agents and Celiums Memory, and nothing reaches the server without passing your rules. This is the rule we recommend for research_source_list:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "research_source_list": {}
  }
}

research_source_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Celiums Memory — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about research_source_list

What does the research_source_list tool do? +

List the sources attached to a research project (id, kind, name, uri, bytes, chunk_count, status, added_at). All local to the user. It is categorised as a Read tool in the Celiums Memory MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on research_source_list? +

Register the Celiums Memory MCP server in PolicyLayer and add a rule for research_source_list: 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 Celiums Memory. Nothing to install.

What risk level is research_source_list? +

research_source_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit research_source_list? +

Yes. Add a rate_limit block to the research_source_list 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.

How do I block research_source_list completely? +

Set action: deny in the PolicyLayer policy for research_source_list. 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.

What MCP server provides research_source_list? +

research_source_list is provided by the Celiums Memory MCP server (terrizoaguimor/celiums-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Celiums Memory tool call.

Start from Celiums Memory, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
