Explain Microsoft Graph delta queries for efficient change tracking — get only changed items since last sync rather than fetching everything.
AI agents call graph_explain_delta to retrieve information from Ms Graph Dev without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool provides explanatory information about how Microsoft Graph delta queries work for change tracking. It retrieves and explains query patterns without executing data modifications, deletions, or financial operations.
From the tool's definition Tool name 'graph_explain_delta' and description explicitly state it 'explain[s]' delta queries and focuses on 'get only changed items' — a read-only, informational operation about query mechanics.

Explain Microsoft Graph delta queries for efficient change tracking — get only changed items since last sync rather than fetching everything. It is categorised as a Read tool in the Ms Graph Dev MCP Server, which means it retrieves data without modifying state.
Register the Ms Graph Dev MCP server in PolicyLayer and add a rule for graph_explain_delta: 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 Ms Graph Dev. Nothing to install.
graph_explain_delta 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 graph_explain_delta 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 graph_explain_delta. 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.
graph_explain_delta is provided by the Ms Graph Dev MCP server (stubbedev/ms-graph-dev-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
