Get markdown content for specified knowledge documents
AI agents call get_knowledge_doc to retrieve information from BNB Chain MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns markdown documentation content. It is a read-only operation that queries knowledge documents without side effects, making it a 'Read' category tool. The severity is low because retrieval of knowledge documentation poses minimal security risk unless the documents themselves contain sensitive information, which is not indicated in the description.
From the tool's definition Tool name 'get_knowledge_doc' and description 'Get markdown content for specified knowledge documents' indicate retrieval of static documentation content with no modification or execution capability.

PolicyLayer is an MCP gateway — it sits between your AI agents and BNB Chain MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_knowledge_doc:
{
"version": "1",
"default": "deny",
"tools": {
"get_knowledge_doc": {}
}
}get_knowledge_doc is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the BNB Chain MCP server in PolicyLayer and add a rule for get_knowledge_doc: 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 BNB Chain MCP. Nothing to install.
get_knowledge_doc 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 get_knowledge_doc 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 get_knowledge_doc. 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.
