Get recent observations of a specific bird species in a region
AI agents call ebird_get_recent_observations_for_species to retrieve information from eBird MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns bird observation data from the eBird database. It performs a read-only lookup operation to fetch recent sightings of a specified species within a geographic region. There is no data modification, deletion, code execution, or financial impact. The only risk is potential information disclosure of bird sighting locations, which is low severity since eBird data is publicly available.
From the tool's definition Tool name 'ebird_get_recent_observations_for_species' and description 'Get recent observations of a specific bird species in a region' both indicate a retrieval operation with no side effects.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches eBird MCP Server. Nothing to install.
ebird_get_recent_observations_for_species 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 ebird_get_recent_observations_for_species 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 ebird_get_recent_observations_for_species. 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.
ebird_get_recent_observations_for_species is provided by the eBird MCP Server MCP server (moonbirdai/ebird-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from eBird MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
