AI agents call list_projects to retrieve information from Synapse without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about indexed projects without side effects. It performs a simple enumeration/listing operation, which is characteristic of Read-category tools. The blast radius if misused by an AI agent is minimal—an agent could only learn what projects exist and when they were indexed, posing no risk to data integrity or system security.
From the tool's definition Tool name is 'list_projects' and description states it 'List all indexed projects' returning metadata (path, languages, timestamp). This is a pure read operation with no modification or execution.
Attacks that exploit this kind of access
List all indexed projects. Returns path, languages (list), and last-indexed timestamp for each. It is categorised as a Read tool in the Synapse MCP Server, which means it retrieves data without modifying state.
Register the Synapse MCP server in PolicyLayer and add a rule for list_projects: 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 Synapse. Nothing to install.
list_projects 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 list_projects 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 list_projects. 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.
list_projects is provided by the Synapse MCP server (synappscodecomprehension/synapps). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
