diff_context
AI agents call diff_context to retrieve information from TempoGraph without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description, the name and sibling tools indicate this is a code analysis/inspection tool that retrieves contextual information about diffs. The pattern of query tools on this server (architecture, dependencies, etc.) suggests data retrieval without modification. The 'context' framing and analysis-oriented server purpose support Read classification.
From the tool's definition Tool name 'diff_context' suggests retrieval of differences/changes in code context. Part of a code graph engine focused on analysis (siblings: architecture, dependencies, dead_code, hotspots). No description provided.
Attacks that exploit this kind of access
diff_context. It is categorised as a Read tool in the TempoGraph MCP Server, which means it retrieves data without modifying state.
Register the TempoGraph MCP server in PolicyLayer and add a rule for diff_context: 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 TempoGraph. Nothing to install.
diff_context 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 diff_context 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 diff_context. 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.
diff_context is provided by the TempoGraph MCP server (tempograph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
