What changelog does on Yaver
AI agents call changelog to retrieve information from Yaver 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 |
|---|---|---|---|
to | string | — | End ref (default: HEAD) |
from | string | — | Start ref/tag (default: previous tag) |
directory | string | — |
Parameters from the server's own tool schema.
Why changelog is rated Low
The changelog tool performs a read-only operation on git history. It queries git data between specified refs/tags and generates a summary. There are no side effects, no data modifications, no deletions, and no code execution triggered by the tool itself. This is a straightforward data retrieval and presentation task, characteristic of Read category tools.
From the tool's definition Tool description: 'Generate a changelog from git history between two refs/tags.' This reads and queries git history to produce a changelog output; it retrieves information without modifying, deleting, or executing external operations.

The rule that runs changelog safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Yaver, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For changelog, this is the rule to start with:
changelog 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 Yaver, apply this rule, and every changelog call is checked against it from then on.
Questions about changelog
Generate a changelog from git history between two refs/tags. It is categorised as a Read tool in the Yaver MCP Server, which means it retrieves data without modifying state.
changelog accepts 3 parameters: to, from, directory. The full parameter table on this page comes from the server's own tool schema.
Register the Yaver MCP server in PolicyLayer and add a rule for changelog: 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 Yaver. Nothing to install.
changelog 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 changelog 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 changelog. 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.
changelog is provided by the Yaver MCP server (yaver-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
