Stream comprehensive tag analysis with usage statistics and note associations
AI agents call streaming-tag-analysis to retrieve information from MCP Index Notes without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing tag metadata and their relationships to notes, producing read-only analysis output. No creation, modification, deletion, or execution of external operations occurs. The blast radius of misuse is minimal - an agent could only retrieve analytical summaries of existing tags, not alter data or trigger side effects.
From the tool's definition Tool performs 'tag analysis' with 'usage statistics and note associations' - retrieves and streams analytical data without modifying underlying notes, tags, or system state. The 'stream' verb indicates data retrieval, not mutation.

Register the MCP Index Notes MCP server in PolicyLayer and add a rule for streaming-tag-analysis: 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 MCP Index Notes. Nothing to install.
streaming-tag-analysis is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the streaming-tag-analysis 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 streaming-tag-analysis. 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.
