Cherry Tool Guide

Cherry Studio injects first-party tools into your session over four MCP servers (`mcp__cherry-tools__*`, `mcp__agent-memory__*`, `mcp__skills__*`, `mcp__mcp-manager__*`) and gives shell-capable general agents bundled runtimes for local execution. The MCP tools act on the running app — the user's knowledge bases, IM channels, schedules, managed CLIs, skill library, and MCP server registry — through boundaries only Cherry owns. Shell and file tools cannot reach those app boundaries correctly; use the bundled runtimes only for the local execution cases routed below.

**This file is a router.** It carries only the global rules and the intent → tool → reference table. Each reference holds that domain's prerequisites, sequencing, conditional availability, output interpretation, recovery, and examples. Read the one reference the task needs (and any it cross-links to) before calling — don't work from this page alone.

Tool names here are fully qualified (`mcp__server__tool`); the exact names exposed in your session are authoritative if they ever differ. This guide never restates argument shapes — **the live tool schema in your session is the authoritative source** for parameter names, enums, and required fields. Read it before every call.

Global rules

• **Check availability first.** Several tools are conditional (each reference says

which). If a tool is not in your live tool list, its capability is unavailable *in this session* — say so honestly and stop; never pretend a call succeeded or fabricate a result.

• **Don't reach around Cherry's mutation boundaries.** Knowledge bases, IM channels,

schedules, managed CLIs, skills, and registered MCP servers are mutated only through these tools. Do not shell out to `npm install`, `git clone`, `crontab`, or hand-edit knowledge or MCP settings files to accomplish these — the tool does bookkeeping (registration, scoping, approval, sync) that a raw shell command skips. Shell is fine for *inspection* (e.g. `command -v` to probe PATH) — just not to perform the owned mutation.

• **Honor approval.** `mcp__cherry-tools__kb_manage`, `mcp__cherry-tools__cli_install`,

`mcp__cherry-tools__session_create`, `mcp__cherry-tools__session_send`, `mcp__skills__install_skill`, and `mcp__mcp-manager__install_mcp_server` are gated by the session's approval mode. Call them only once the user's intent is clear; if approval is declined, stop and report — do not retry the same effect through another route.

• **Intent still gates auto-approved effects.** Memory writes, schedule changes,

notifications, and agent/channel configuration may execute without an approval card. Do not call them merely because they are available; first make sure the user requested the effect or it is necessary to complete an already-approved task.

When a tool isn't there

Two different situations, don't confuse them:

• **The tool is absent from your live list** →
