A note from us

We have been building tools and systems for ourselves for the past two years. The fact that this repo is small and has few stars is not because it is new. It is because we only just decided to share what we have built. It is not a fresh experiment, it is a long story with a recent commit.

We love building things and sharing them. We do not love social media tactics, growth hacks, or chasing stars and followers. So this repo is small. The code is real, it gets used, issues get answered. Judge for yourself.

If it helps you, sharing, testing, and feedback help us. If it could be better, an issue is more useful. If you build something with it, tell us at hello@studiomeyer.io. That genuinely makes our day.

From a small studio in Palma de Mallorca.

What is this?

StudioMeyer Crew turns Claude into specialized expert roles — CEO, CFO, CMO, CTO, PM, Analyst, Support, Creative Director — with domain-specific frameworks, decision models, and chained workflows. Zero extra API cost because it runs within your Claude subscription.

16 MCP tools for persona activation, status, feedback, custom personas, multi-persona workflows, blind-vote councils/debates, and standing teams. Personas and workflows are also exposed as browsable MCP resources.

12 Tools

| Tool | Description | |------|-------------| | crew_guide | Help and onboarding (5 topics) | | crew_list | List personas by category | | crew_activate | Activate a persona with optional business context | | crew_deactivate | Return to default Claude | | crew_status | Show active persona + duration | | crew_feedback | Rate persona performance (1–5) | | crew_create | Create custom persona | | crew_delete | Delete custom persona (built-in protected) | | crew_workflow_list | List multi-persona workflows | | crew_workflow_run | Run a workflow (sequential persona chain) | | crew_council | Convene a council/debate — N personas answer one question independently (blind), then synthesis | | crew_ensemble | Summon a standing team (board, product-team, …) you converse with; address roles on demand |

3 Workflows

Workflows chain multiple personas for complex tasks:

• Strategy Review — CEO analyzes → CFO evaluates financials → CTO checks feasibility
• Content Pipeline — CMO drafts → Analyst fact-checks → Creative polishes
• Product Launch — PM scopes → Creative writes copy → CMO plans distribution

Councils & Teams

Beyond sequential workflows:

• crew_council runs several personas on the same question independently (blind first-pass, anti-anchoring) then synthesizes consensus, real dissent and a recommendation. mode: "debate" forces genuine disagreement (steelman the counter-position); an optional in-role judge arbitrates.
• crew_ensemble summons a standing multi-voice team (board, product-team, content-studio, growth-pod, founders-room — or an ad-hoc list) that you keep talking to, addressing roles on demand ("CFO, what about the runway?").
• Optional flags: crmBrief: true pulls live CRM numbers first; pdf: true offers a shareable PDF session-protocol.

Resources

Personas and workflows are browsable as MCP resources — preview them without activating. resources/templates/list advertises the dynamic URIs:

• crew://persona/{name} — full persona definition (e.g. crew://persona/cto)
• crew://workflow/{name} — rendered workflow chain

Pricing

• Free — All 16 tools, all 13 personas, all 3 workflows + councils & teams. No credit card.
• Pro / Team / Scale — coming soon (custom personas at scale, team SSO, audit logs)

See studiomeyer.io/en/services/crew for plan details.

Why this approach?

Multi-agent fleets are expensive. Every agent needs its own LLM API call.

Crew runs as one MCP server that swaps Claude's persona on demand. The reasoning still happens in your normal Claude subscription — no extra inference costs, no agent orchestration layer, no token accounting per persona.

You get the focused-expert effect (CFO answers financial questions like a CFO, not a generalist) without the bills.
