mureo Shared Patterns

This file covers authentication, security rules, output formatting, and MCP configuration shared across all mureo skills (Google Ads, Meta Ads, Strategy).

Overview

mureo is a local-first control plane for AI ad ops. It sits on top of the official ad-platform MCPs (Meta Ads MCP, Google Ads MCP, etc.) and provides the layer they cannot — strategy enforcement, outcome correlation, and an auditable decision log. It provides:

• CLI (mureo) for direct command-line usage
• MCP Server for integration with AI agent hosts (Claude Code, Cursor, Codex, Gemini, etc.)
• Python library for programmatic access

All three interfaces share the same authentication, security rules, and output format.

Installation

pip install mureo

Setup

Claude Code (Recommended)

mureo setup claude-code

This launches a wizard that:

1. Asks which platforms to configure (Google Ads / Meta Ads)
2. Collects API credentials
3. Opens a browser for OAuth authorization
4. Lists accessible accounts for selection
5. Saves credentials to ~/.mureo/credentials.json

Manual Configuration

Create ~/.mureo/credentials.json:

{
  "google_ads": {
    "developer_token": "YOUR_DEVELOPER_TOKEN",
    "client_id": "YOUR_OAUTH_CLIENT_ID",
    "client_secret": "YOUR_OAUTH_CLIENT_SECRET",
    "refresh_token": "YOUR_REFRESH_TOKEN",
    "login_customer_id": "1234567890"
  },
  "meta_ads": {
    "access_token": "YOUR_LONG_LIVED_TOKEN",
    "app_id": "YOUR_APP_ID",
    "app_secret": "YOUR_APP_SECRET",
    "account_id": "act_XXXXXXXXXXXX"
  }
}

Environment Variable Fallback

If ~/.mureo/credentials.json is not found, mureo reads from environment variables:

Platform	Variable	Required
Google Ads	GOOGLE_ADS_DEVELOPER_TOKEN	Yes
Google Ads	GOOGLE_ADS_CLIENT_ID	Yes
Google Ads	GOOGLE_ADS_CLIENT_SECRET	Yes
Google Ads	GOOGLE_ADS_REFRESH_TOKEN	Yes
Google Ads	GOOGLE_ADS_LOGIN_CUSTOMER_ID	No
Meta Ads	META_ADS_ACCESS_TOKEN	Yes
Meta Ads	META_ADS_APP_ID	No
Meta Ads	META_ADS_APP_SECRET	No

Verify Authentication

# Show auth status for all platforms
mureo auth status

# Check Google Ads credentials (masked output)
mureo auth check-google

# Check Meta Ads credentials (masked output)
mureo auth check-meta

Tool Selection (host-portable patterns)

Skills and commands describe "Read STRATEGY.md", "Update STATE.json", and "Append to action_log" in prose. These map to different tools depending on the host, but the intent is identical:

Action	Claude Code	Claude Desktop chat / Cowork / claude.ai web
Read STRATEGY.md	Read tool	mureo_strategy_get MCP tool
Replace STRATEGY.md	Write / Edit tool	mureo_strategy_set MCP tool
Read STATE.json	Read tool	mureo_state_get MCP tool
Append action_log entry	Edit tool (modify JSON)	mureo_state_action_log_append MCP tool
Upsert campaign snapshot	Edit tool (modify JSON)	mureo_state_upsert_campaign MCP tool

When you don't have direct filesystem tools (Desktop / Cowork / web), always reach for the corresponding mureo_* MCP tool — they encode the same atomic-write semantics so you can't corrupt the file mid-edit.

The platform tools (google_ads_*, meta_ads_*, search_console_*) are the same across all hosts because they only exist as MCP tools.

Plugin platforms (third-party providers)

Beyond the built-in platforms, an entry-point provider installed as a mureo plugin can expose its own operations as mcp__mureo__<plugin>_* tools. When a workflow enumerates "all configured platforms", also enumerate these plugin tools and include each plugin platform on a best-effort, clearly-labelled line (e.g. Acme Ads (plugin) — …), driving it with the plugin's own tools as their names/descriptions imply.

Honest scope for a plugin platform:

• Include the basic listing / performance / health its tools support.
• Skip mureo-only value-adds — anomaly detection, result_indicator CV-mismatch, RSA-asset audit, rule-based scoring. These are platform-specific to the built-ins and do not exist for plugins; say so in the output.
• Plugin tool calls are already audited by mureo, and successful mutations promoted into action_log (platform="plugin:<dist>") when run in a strategy workspace (a STATE.json exists). Treat plugin read findings as advisory; do not assume mureo's strategy/rollback guarantees beyond what action_log records (an arbitrary plugin operation is not auto-reversible).
• Plugin tool-name mapping is best-effort (infer from the live tool list), not deterministic. Never fail the whole workflow because a plugin tool is missing — report it and continue with the built-ins.

Mutating plugin tools — structural strategy parity

A mutating plugin tool (anything not declared readOnlyHint) is subject to the same structural strategy handling as a built-in write, even though mureo has no platform-specific analytics for it:

• Confirm before the call. The Security Rules → Confirm Before Write Operations requirement applies to plugin write tools exactly as it does to google_ads_* / meta_ads_* writes — show the user what will change and get explicit approval first.
• Gate against strategy. Before the call, read STRATEGY.md (Operation Mode, Goals, brand/rules) and STATE.json. If the mutation conflicts with the current Operation Mode or a Goal, do not run it — surface the conflict and let the user decide, the same as you would for a built-in write.
• Outcome review is automatic. The promoted action_log entry carries an observation_due window, so daily-check's evidence step reviews its outcome like a built-in. There is no metrics_at_action baseline (platform-specific analytics do not exist for a plugin) — evaluate that entry qualitatively/advisory and never attribute metric movement to it without an independent check.

What does not reach parity (by design, state it in output): mureo's platform-specific analytics — anomaly detection, result_indicator CV-mismatch, RSA-asset audit, rule-based scoring — and automatic rollback (only built-in allow-listed operations are auto-reversible; a plugin reversal hint is recorded for visibility, not executed).

Optional: analytics-module parity (Issue #120)

A plugin author OR an official-MCP wrapper can opt into mureo's analytics surface by registering an AnalyticsModule (entry-point group mureo.analytics; see docs/plugin-authoring.md → Shipping analytics with your plugin). When a module is registered:

• The MCP tool mureo_analytics_modules_list reports which platforms have analytics and which capabilities each advertises (detect_anomalies, diagnose_performance, audit_creative, analyze_budget_efficiency).
• Workflow skills (daily-check, rescue, …) consult that list before running deep diagnostics on an external-integration platform: if the platform has no module or the needed capability is missing, the skill must say analytics_not_available_for_<platform> in its output rather than invent heuristics from the integration's tool schemas. Auto-deriving analytics is unsafe (would produce plausible-but-wrong analysis) and is explicitly out of scope.
• Built-in google_ads and meta_ads ship analytics modules for the capabilities they support today; new platforms get parity by hand-authoring a module, not by code generation.

MCP Server Configuration

Claude Code / Cursor

Add to your MCP client configuration:

{
  "mcpServers": {
    "mureo": {
      "command": "python",
      "args": ["-m", "mureo.mcp"]
    }
  }
}

The MCP server exposes tools for Google Ads, Meta Ads, and Search Console over stdio.

Verify MCP Connection

Once configured, the AI agent can call google_ads_campaigns_list or meta_ads_campaigns_list to verify the connection is working.

Security Rules

CRITICAL: AI agents MUST follow these rules when using mureo tools.

1. Confirm Before Write Operations

Always confirm with the user before executing any write operation:

• create (campaigns, ad groups, ads, keywords, audiences)
• update (settings, status, budgets, bids)
• update_status (enable, pause, remove)
• add / remove (keywords, negative keywords)

Example agent behavior:

User: "Pause campaign 123456"
Agent: "I'll pause campaign 123456 (Brand Search - Tokyo).
        Current status: ENABLED, 12 active ads, daily budget 5,000.
        Proceed? [y/n]"

2. Budget Changes Require Current Value Display

Before updating any budget, always retrieve and display the current budget first:

1. Call google_ads_budget_get or read campaign details
2. Show the user: current amount, new amount, and percentage change
3. Warn if the change exceeds 20% (significant impact on delivery)

3. Bulk Pause/Remove with Extra Caution

When pausing or removing multiple entities:

• List all affected entities with their current performance
• Show total impact (e.g., "This will pause 5 campaigns with 1,200 clicks/day")
• Require explicit confirmation

4. Never Expose Raw Credentials

• Never include token values from credentials.json in responses
• Use mureo auth check-google / mureo auth check-meta for masked output
• If a user asks to see credentials, show masked values only

5. Keyword Operations: Execute in Stages

When adding or removing large numbers of keywords:

• Batch into groups of 20 or fewer
• Show progress after each batch
• Allow the user to stop between batches

6. Learning Period Awareness

For Google Ads campaigns using smart bidding:

• Warn before making changes that reset the learning period
• Affected operations: bidding strategy changes, budget changes > 20%, conversion setting changes
• Display the current bidding system status if available

Output Format

All tools return structured JSON via TextContent. The format depends on the tool category:

  "campaigns": [
    {
      "campaign_id": "12345",
      "name": "Brand Search",
      "status": "ENABLED",
      "bidding_strategy_type": "MAXIMIZE_CONVERSIONS",
      "daily_budget": 5000.0
    }
  ]
}

Error Response

{
  "error": "Campaign not found: 99999",
  "error_code": "NOT_FOUND"
}

Authentication Error

{
  "error": "No credentials found. Set environment variables (GOOGLE_ADS_DEVELOPER_TOKEN, ...) or ~/.mureo/credentials.json"
}
