snapshot_llm_citations · Geoseo MCP: Risk & Policy

WHAT IT DOES

What snapshot_llm_citations does on Geoseo

AI agents use snapshot_llm_citations to create or update resources in Geoseo — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Geoseo environment.

WHY IT NEEDS A POLICY

Why snapshot_llm_citations needs a policy

The tool both queries multiple LLMs for citation data (Read/Execute) and persists the results to storage (Write). Per the severity hierarchy, Write outranks Read. The blast radius is medium since misuse could store incorrect or polluted citation data, but it does not delete or move money.

From the tool's definition "persist the per-question results" indicates data is written/stored; "Run multi-LLM citation check" is the read/execute portion

snapshot_llm_citations Rate-limited

snapshot_llm_citations stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
