Add a text or markdown document to the RAG system. Supports hierarchical chunking for markdown. Optionally add tags and base_path for organization.
AI agents use add_document to create or update resources in RAG Document Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your RAG Document Server environment.
This tool creates and stores new documents in the RAG system, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. Severity is medium because malicious document injection could pollute the knowledge base, degrade search quality, or introduce misleading information that an AI agent might rely upon—but the effect is limited to the document store and can be remediated…
From the tool's definition Tool name 'add_document' and description 'Add a text or markdown document to the RAG system' explicitly indicate creation of new data. The phrase 'Optionally add tags and base_path for organization' confirms data modification/creation capability.
Attacks that exploit this kind of access
Add a text or markdown document to the RAG system. Supports hierarchical chunking for markdown. Optionally add tags and base_path for organization. It is categorised as a Write tool in the RAG Document Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the RAG Document Server MCP server in PolicyLayer and add a rule for add_document: 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 RAG Document Server. Nothing to install.
add_document is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the add_document 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 add_document. 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.
add_document is provided by the RAG Document Server MCP server (jaimeferj/mcp-rag-docs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
add_document is one line of RAG Document Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
