Return source, version, cache, and size metadata for the latest AsyncAPI specification.
AI agents call get_asyncapi_spec_metadata to retrieve information from AsyncAPI-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 queries metadata about the AsyncAPI specification. It performs no side effects, does not modify data, does not execute code or commands, and does not delete or move resources. It is a straightforward data retrieval operation, consistent with the 'Read' category for tools that search, list, get, or fetch information.
From the tool's definition Tool 'get_asyncapi_spec_metadata' returns metadata (source, version, cache, size) for the AsyncAPI specification. The verb 'Return' and the nature of metadata retrieval indicate a read-only operation with no data modification, creation, or external execution.
Attacks that exploit this kind of access
Return source, version, cache, and size metadata for the latest AsyncAPI specification. It is categorised as a Read tool in the AsyncAPI-MCP MCP Server, which means it retrieves data without modifying state.
Register the AsyncAPI- MCP server in PolicyLayer and add a rule for get_asyncapi_spec_metadata: 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 AsyncAPI-MCP. Nothing to install.
get_asyncapi_spec_metadata 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_asyncapi_spec_metadata 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_asyncapi_spec_metadata. 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.
get_asyncapi_spec_metadata is provided by the AsyncAPI- MCP server (souvikns/asyncapi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
