What get_server_log_checkpoint does on Meridian
AI agents call get_server_log_checkpoint to retrieve information from Meridian 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 |
|---|---|---|---|
seek_to | string | — | Optional ISO timestamp (UTC). When provided, returns a seek_hint field with the best since= value to pass to get_server_logs to start near this timestamp. Examp |
Parameters from the server's own tool schema.
Why get_server_log_checkpoint is rated Low
This tool retrieves metadata about log positions without altering any state. It is a pure read operation that returns positional/checkpoint information to facilitate efficient querying of existing logs. There is no data modification, code execution, or destructive capability. Low severity due to the read-only nature and the fact that it only exposes log navigation metadata rather than sensitive log content itself.
From the tool's definition Tool is explicitly marked '[MAINTENANCE] Read-only' and described as returning a 'checkpoint index for the server_logs ring-buffer' and 'table of contents mapping'.

The rule that runs get_server_log_checkpoint safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Meridian, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_server_log_checkpoint, this is the rule to start with:
get_server_log_checkpoint 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 Meridian, apply this rule, and every get_server_log_checkpoint call is checked against it from then on.
Questions about get_server_log_checkpoint
[MAINTENANCE] b241a437 -- Read-only: Return the positional/checkpoint index for the server_logs ring-buffer. The checkpoint is a lightweight 'table of contents' mapping minute-level timestamp buckets to the first/last row id and row count in that bucket. Use this for fast navigation through large log windows: find the bucket just before your target timestamp, then use its min_recorded_at as the since= argument to get_server_logs to skip all older rows without scanning. Complementary to search_server_logs (BM25 text search): this is positional navigation (WHERE in the log?) not semantic ranking (WHAT text?). The optional seek_to= argument returns the best since= hint directly. The index is rebuilt from the in-memory snapshot on every get_server_logs / search_server_logs call, so it is always current. Returns {total_rows, bucket_granularity_label, min_recorded_at, max_recorded_at, bucket_count, buckets:[{bucket, count, min_recorded_at, max_recorded_at, first_id, last_id}], seek_hint (when seek_to= given)}. It is categorised as a Read tool in the Meridian MCP Server, which means it retrieves data without modifying state.
get_server_log_checkpoint accepts 1 parameter: seek_to. The full parameter table on this page comes from the server's own tool schema.
Register the Meridian MCP server in PolicyLayer and add a rule for get_server_log_checkpoint: 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 Meridian. Nothing to install.
get_server_log_checkpoint 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_server_log_checkpoint 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_server_log_checkpoint. 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_server_log_checkpoint is provided by the Meridian MCP server (@meridianmcp/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
