What bgs-ogcapi.geology.bedrock does on Apibase
AI agents call bgs-ogcapi.geology.bedrock to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
lat | number | — | Decimal degree latitude (WGS84) — must be supplied together with lng. Omit both for full Great Britain coverage. |
lng | number | — | Decimal degree longitude (WGS84) — must be supplied together with lat. |
limit | integer | — | Maximum bedrock geology units to return (default 20, max 50) |
radius_km | number | — | Search radius in kilometres around lat/lng (default 5, max 50) |

Attacks that exploit this kind of access
The rule that runs bgs-ogcapi.geology.bedrock safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For bgs-ogcapi.geology.bedrock, this is the rule to start with:
bgs-ogcapi.geology.bedrock is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Apibase, apply this rule, and every bgs-ogcapi.geology.bedrock call is checked against it from then on.
Questions about bgs-ogcapi.geology.bedrock
Look up bedrock geology (lithology, rock unit name, and geological age range) near a point in Great Britain, from the BGS 1:625,000 generalised digital geological map.

Data: British Geological Survey (ogcapi.bgs.ac.uk), Open Government Licence, no auth required. It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
bgs-ogcapi.geology.bedrock accepts 4 parameters: lat, lng, limit, radius_km. The full parameter table on this page comes from the server's own tool schema.
Register the Apibase MCP server in PolicyLayer and add a rule for bgs-ogcapi.geology.bedrock: 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 Apibase. Nothing to install.
bgs-ogcapi.geology.bedrock 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 bgs-ogcapi.geology.bedrock 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 bgs-ogcapi.geology.bedrock. 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.
bgs-ogcapi.geology.bedrock is provided by the Apibase MCP server (apibase-mcp-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
