Claude for Financial Services

Reference agents, skills, and data connectors for the financial-services workflows we see most — investment banking, equity research, private equity, and wealth management.

Everything here is available two ways from one source: install it as a Claude Cowork plugin, or deploy it through the Claude Managed Agents API behind your own workflow engine. Same system prompt, same skills — you choose where it runs.

Nothing in this repository constitutes investment, legal, tax, or accounting advice. These agents draft analyst work product — models, memos, research notes, reconciliations — for review by a qualified professional. They do not make investment recommendations, execute transactions, bind risk, post to a ledger, or approve onboarding; every output is staged for human sign-off. You are responsible for verifying outputs and for compliance with the laws and regulations that apply to your firm.

What’s in the repo:

• Agents — named, end-to-end workflow agents (Pitch Agent, Market Researcher, GL Reconciler, …). Each ships as a Cowork plugin and as a Claude Managed Agent template you deploy via /v1/agents.
• Vertical plugins — the underlying skills, slash commands, and data connectors, bundled by FSI vertical. Install these on their own if you just want /comps, /dcf, /earnings and the connectors without a full agent.

Agents

Each agent is named for the workflow it runs. They’re starting points: install the ones that match your work, then tune the prompts, skills, and connectors to how your firm does it. Each agent plugin is self-contained — it bundles the skills it uses, so installing the agent is all you need.

For Managed Agent deployment — agent.yaml, leaf-worker subagents, steering-event examples, and per-agent security notes — see managed-agent-cookbooks/.

Getting Started

Cowork

In Cowork, open Settings → Plugins → Add plugin and either:

• Paste this repo URL — https://github.com/anthropics/claude-for-financial-services — then pick the agents and verticals you want from the marketplace list, or
• Upload a zip — zip any directory under plugins/ (e.g. plugins/agent-plugins/pitch-agent/) and drop it in.

Claude Code

# Add the marketplace
claude plugin marketplace add anthropics/claude-for-financial-services

# Core skills + connectors (install first)
claude plugin install financial-analysis@claude-for-financial-services

# Named agents — pick the ones you want
claude plugin install pitch-agent@claude-for-financial-services
claude plugin install gl-reconciler@claude-for-financial-services
claude plugin install market-researcher@claude-for-financial-services

# Vertical skill bundles
claude plugin install investment-banking@claude-for-financial-services
claude plugin install equity-research@claude-for-financial-services

Once installed, agents appear in Cowork dispatch, skills fire automatically when relevant, and slash commands are available in your session (/comps, /dcf, /earnings, /ic-memo, …).

Claude Managed Agents

export ANTHROPIC_API_KEY=sk-ant-...
scripts/deploy-managed-agent.sh gl-reconciler

Each template under managed-agent-cookbooks/ references the same system prompt and skills as its plugin counterpart. The deploy script resolves file references, uploads skills, creates leaf-worker subagents, and POSTs the orchestrator to /v1/agents. See scripts/orchestrate.py for a reference event loop that routes handoff_request events between agents via your own orchestration layer.

Research Preview: subagent delegation (callable_agents) is a preview capability. See per-agent READMEs for security and handoff guidance.

How It Fits Together

Everything is file-based — markdown and JSON, no build step.

Vertical Plugins

Start with financial-analysis — it carries the shared modeling skills and all data connectors. Add verticals for the workflows you need.

MCP Integrations

All connectors are centralized in the financial-analysis core plugin and shared across the rest.

MCP access may require a subscription or API key from the provider.

Claude for Microsoft 365 — Install Tooling

If your firm runs Claude inside Excel, PowerPoint, Word, and Outlook via the Microsoft 365 add-in, claude-for-msft-365-install/ is the admin tooling to provision it against your own cloud — Vertex AI, Bedrock, or an internal LLM gateway — instead of Anthropic’s API. It’s a Claude Code plugin (not a Cowork plugin) that walks an IT admin through generating the customized add-in manifest, granting Azure admin consent, and writing per-user routing config via Microsoft Graph.

Install with:

claude plugin install claude-for-msft-365-install@claude-for-financial-services
/claude-for-msft-365-install:setup

This is separate from the agents and vertical plugins above — it’s the on-ramp that gets the add-in deployed in a tenant, after which the agents and skills here are what runs inside it.

Making It Yours

These are reference templates — they get better when you tune them to how your firm works.

• Swap connectors — point .mcp.json at your data providers and internal systems.
• Add firm context — drop your terminology, processes, and formatting standards into skill files.
• Bring your templates — /ppt-template teaches Claude your branded PowerPoint layouts.
• Adjust agent scope — edit agents/.md to match how your team actually runs the workflow.
• Add your own — copy the structure for workflows we haven’t covered.

Skill & Command Reference
