AI agents call get_traceability to retrieve information from Wassden without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query/reporting function on development artifacts (requirements, design, task mappings). It has no side effects, does not execute code or external operations, and does not alter any state. The read-only designation and reporting nature clearly place it in the Read category with low severity.
From the tool's definition Tool description explicitly states '[READ-ONLY]' and 'Generate current traceability report' — it retrieves and presents existing mappings without modifying, creating, or deleting data.
Attacks that exploit this kind of access
[READ-ONLY] Generate current traceability report showing REQ↔DESIGN↔TASK mappings. It is categorised as a Read tool in the Wassden MCP Server, which means it retrieves data without modifying state.
Register the Wassden MCP server in PolicyLayer and add a rule for get_traceability: 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 Wassden. Nothing to install.
get_traceability 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 get_traceability 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 get_traceability. 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.
get_traceability is provided by the Wassden MCP server (tokusumi/wassden-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
