List all supported input formats and processing pipelines
AI agents call list_supported_formats to retrieve information from Document Parser MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves configuration or metadata information without modifying, executing, or deleting any data. It is a pure read operation with minimal blast radius if misused by an AI agent, as it can only expose system capabilities information.
From the tool's definition Tool name 'list_supported_formats' and description 'List all supported input formats and processing pipelines' indicate a query operation that retrieves and returns information about supported document formats and pipelines with no side effects.
Attacks that exploit this kind of access
List all supported input formats and processing pipelines. It is categorised as a Read tool in the Document Parser MCP MCP Server, which means it retrieves data without modifying state.
Register the Document Parser MCP server in PolicyLayer and add a rule for list_supported_formats: 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 Document Parser MCP. Nothing to install.
list_supported_formats 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_supported_formats 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_supported_formats. 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_supported_formats is provided by the Document Parser MCP server (kgand/document-parser-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_supported_formats is one line of Document Parser's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
