Get a document from a database
AI agents call getDocument to retrieve information from CouchDB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a single document from a CouchDB database. It performs a query operation that reads data without side effects—no data is created, modified, deleted, or executed. While the server provides destructive tools like 'deleteDatabase' and 'deleteMangoIndex', this specific tool is purely for data retrieval, making it a Read category risk with low severity.
From the tool's definition Tool name 'getDocument' and description 'Get a document from a database' indicate a retrieval operation with no modification or deletion of data.

Register the CouchDB MCP Server MCP server in PolicyLayer and add a rule for getDocument: 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 CouchDB MCP Server. Nothing to install.
getDocument 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 getDocument 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 getDocument. 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.
getDocument is provided by the CouchDB MCP Server MCP server (robertoamoreno/couchdb-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
