Decompress previously compressed data. Requires the base64 compressed data and the algorithm used.
AI agents call decompress to retrieve information from Mcp Compress without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Decompression is a data retrieval and transformation operation that reconstructs original content from compressed input. It produces output based on input parameters but does not create, modify, delete, or irreversibly alter any stored data. The operation is read-only in nature—it reads compressed data and returns decompressed data without side effects. No financial, destructive, or arbitrary code execution occurs.

Attacks that exploit this kind of access
Decompress previously compressed data. Requires the base64 compressed data and the algorithm used. It is categorised as a Read tool in the Mcp Compress MCP Server, which means it retrieves data without modifying state.
Register the Mcp Compress MCP server in PolicyLayer and add a rule for decompress: 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 Compress. Nothing to install.
decompress 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 decompress 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 decompress. 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.
decompress is provided by the Mcp Compress MCP server (shipitandpray/mcp-compress). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
