# planetscale-mcp-agent-operating-model

Configures safe agent operations with PlanetScale MCP. It lets agents inspect telemetry and open migration PRs while blocking direct changes to production.

## What it does

The skill sets strict boundaries for coding agents using PlanetScale MCP. Agents prefer the insights-only server by default to inspect telemetry and schema recommendations. When a task requires the full MCP server, write tools remain disabled unless an operator grants explicit approval.

It guides teams to define database parameters inside a project `AGENTS.md` file, covering organization name, branch targets, and engine types like Vitess or Postgres. Autonomous agents can safely correlate query patterns with code, create development branches, apply DDL in isolation, and open deploy requests for human review.

Direct DDL execution, production data writes, credential rotation, and webhook creation are blocked by default. Because human review is required before merging or deploying, the database stays protected from uncontrolled mutations.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add planetscale/skills --skill planetscale-mcp-agent-operating-model -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/planetscale-mcp-agent-operating-model/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/planetscale-mcp-agent-operating-model/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add planetscale/skills --skill planetscale-mcp-agent-operating-model -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/planetscale-mcp-agent-operating-model/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add planetscale/skills --skill planetscale-mcp-agent-operating-model -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/planetscale-mcp-agent-operating-model/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install planetscale/skills planetscale-mcp-agent-operating-model
```

2. **Manually: put the files in place**
- File: `.github/skills/planetscale-mcp-agent-operating-model/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add planetscale/skills --skill planetscale-mcp-agent-operating-model -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/planetscale/skills --path planetscale-mcp-agent-operating-model
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/planetscale-mcp-agent-operating-model/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add planetscale/skills --skill planetscale-mcp-agent-operating-model -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/planetscale/skills/tree/HEAD/planetscale-mcp-agent-operating-model/SKILL.md

## When to use it
- block autonomous write queries against production databases
- prepare non-production branches and deploy requests from schema suggestions
- trace Insights regressions to source routes and repository commits
- audit query tag coverage across repository code

## Example prompts
- Check recent schema recommendations via PlanetScale MCP and create a dev branch with the migration
- Correlate the latest Insights query regressions with our repository commits

# MCP agent operating model

## Purpose

Define how agents should use PlanetScale MCP safely. Agents should use production telemetry to generate useful work while avoiding autonomous production changes.

## Default MCP choice

Use the PlanetScale MCP insights-only server when the task only needs Insights and Schema Recommendations.

Use the full PlanetScale MCP server only when the task explicitly requires database/schema access beyond Insights. Prefer read-only scopes.

The full MCP server has query execution tools. Treat write query tools as disabled unless the operator explicitly approves a specific non-production action or a carefully reviewed production action.

## AGENTS.md guidance

Two different documents both named `AGENTS.md` serve different purposes:

1. **CLI agent guide** — shipped with `pscale` (`AGENTS.md` in the
   [planetscale/cli](https://github.com/planetscale/cli) repo, or
   `pscale agent-guide --format json`). Covers auth, `--format json`, flag
   placement, and `pscale sql`. Load skill `planetscale-pscale-cli-automation` for the
   same conventions inside this skills pack.

2. **Project agent guide** — your application repository's `AGENTS.md` (or
   equivalent). Covers database targeting and approval policy for *this* app.

When working inside a repository, recommend adding a **project** database
targeting section to `AGENTS.md` or equivalent project instructions:

- PlanetScale organization.
- Database.
- Branch.
- Engine: Vitess or Postgres.
- Production branch name.
- Whether agents may use MCP insights-only or full MCP.
- Whether write queries are forbidden.
- Required approval protocol for schema, Traffic Control, webhooks, roles, and network changes.

Do not edit `AGENTS.md` without approval.

## Safe autonomous tasks

Allowed by default:

- Read Insights.
- Read schema recommendations.
- Read schema metadata.
- Read existing webhooks and Traffic Control configuration.
- Read branch metadata.
- Inspect repository code.
- Correlate query patterns with code.
- File issues.
- Open pull requests.
- Create development branches.
- Apply DDL and migrations to non-production development branches.
- Open deploy requests into branches protected by a review workflow.
- Draft Traffic Control budget proposals.
- Draft webhook receiver requirements.
```
