Claude Plugins for Finance and Blockchain Applications: The Complete Guide

The TRES Finance plugin is the only finance and blockchain Claude plugin available in the anthropics/claude-plugins-community repository, offering 14 specialized skills for crypto accounting, on-chain data analysis, and ledger management.

If you're looking for Claude plugins for finance and blockchain applications, the anthropics/claude-plugins-community repository maintains a single, purpose-built solution. The TRES Finance plugin provides a production-ready MCP (Managed-Code-Platform) connector that lets Claude Code interact directly with on-chain data, perform crypto-asset accounting, and automate reconciliation workflows.

TRES Finance Plugin Overview

The tres-finance-plugin is the sole community-contributed plugin targeting finance and blockchain use cases in the repository. It bundles an MCP connector at https://ai.tres.finance/mcp and a comprehensive catalog of skills for crypto-native workflows.

Attribute	Value
Plugin ID	tres-finance-plugin
Installation	/plugin marketplace add tres-finance/tres-finance-plugin or claude --plugin-dir ./tres-finance-plugin
MCP Endpoint	https://ai.tres.finance/mcp (configured in .mcp.json)
Optional Config	DEBANK_API_KEY for balance validation (defined in .claude-plugin/plugin.json)

According to the source code in tres-finance-plugin/.claude-plugin/plugin.json, the plugin exposes a userConfig schema that accepts an optional DeBank API key for enhanced balance verification capabilities.

Core Architecture

The plugin follows a modular skill-based architecture defined across four key file types:

1. .claude-plugin/plugin.json — Stores plugin metadata, version, author, and the DEBANK_API_KEY user configuration field.

2. .mcp.json — Defines the MCP connector pointing to the TRES Finance GraphQL server. All skills route through this endpoint using built-in execute and build_query tools.

3. skills/ directory — Contains self-contained skill subdirectories, each with a SKILL.md file mapping natural-language triggers to MCP operations.

4. README.md — Provides the skill catalog and high-level documentation.

No additional binaries or external services are required beyond the optional DeBank API integration.

Complete Finance & Blockchain Skill Catalog

The plugin ships 14 specialized skills covering wallet management, transaction analysis, balance validation, reporting, and ERP integration:

Wallet & Transaction Management

• tres-wallets-upload — Bulk onboard on-chain wallets and exchange accounts. Trigger: "Upload my crypto wallets"

• tres-tx-story — Generate animated SVG flow diagrams and plain-language explanations of blockchain transactions. Trigger: "Explain transaction 0xabc…"

• tres-explorer-tx-to-ledger — Parse Etherscan, Polygonscan, or similar explorer URLs and create structured ledger entries. Trigger: "Add this explorer link to my ledger"

Validation & Reconciliation

• tres-asset-balance-validation — Compare on-chain balances (via DeBank) against TRES Finance records and generate discrepancy reports. Requires DEBANK_API_KEY. Trigger: "Validate my wallet balances"

• tres-recon-gaps — Identify and resolve reconciliation gaps in the ledger. Trigger: "Find reconciliation gaps"

• tres-upload-tx-header-validation — Validate CSV header names for bulk transaction uploads. Trigger: "Check my transaction CSV headers"

Reporting & Analysis

• tres-report-advisor — Recommend appropriate TRES Finance reports for user goals. Trigger: "Which report should I run for month-end close?"

• tres-report-analyzer — Parse XLSX exports and summarize findings, anomalies, and action items. Trigger: "Analyze this audit report"

• tres-cost-basis — View, modify, and export cost-basis calculations and strategy status. Trigger: "Show my cost-basis status"

ERP & Accounting Rules

• tres-erp-rule-suggestions — Assist with crypto-focused ERP rule creation for mapping on-chain activity to accounting entries. Trigger: "Help me create ERP rules for crypto trades"

• tres-rollup-rules / tres-rollup-review — Discover, propose, and review sub-transaction rollup rules for cleaner ledgers. Trigger: "Suggest rollup rules for my wallet"

Administration

• tres-onboarding — End-to-end onboarding of new entities, customers, or accounts. Trigger: "Onboard a new crypto entity"

• tres-settings-management — View or modify platform configuration including blockchains, exchanges, and sync filters. Trigger: "Update my blockchain settings"

• tres-request-skill-update — Submit feedback or feature requests for any TRES Finance skill. Trigger: "Report a bug in the wallet upload skill"

Practical Usage Examples

Install the plugin using either method:

/plugin marketplace add tres-finance/tres-finance-plugin

Or for local development:

claude --plugin-dir ./tres-finance-plugin

Example 1: Upload Wallet Addresses

Upload my crypto wallets:
- 0xAaBbCcDdEeFf00112233445566778899aAbBcCdD (Ethereum)
- 0x1234567890abcdef1234567890abcdef12345678 (Polygon)

Claude Code invokes tres-wallets-upload, validates the addresses, and prompts for confirmation before creating records.

Example 2: Visualize a Transaction

Explain transaction 0x9f8e7d6c5b4a3210fedcba9876543210abcdef12

The tres-tx-story skill fetches the transaction, builds an SVG flow diagram, and returns a plain-language narrative.

Example 3: Validate On-Chain Balances

Validate my wallet balances using DeBank.

Claude Code calls tres-asset-balance-validation, pulls current token amounts via the configured DEBANK_API_KEY, compares against TRES Finance records, and generates an HTML/PDF discrepancy report.

Example 4: Import Explorer Data

Add this Etherscan link to my ledger:
https://etherscan.io/tx/0x5d1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b

The tres-explorer-tx-to-ledger skill parses the explorer page and creates a structured ledger entry.

Frequently Asked Questions

Are there other finance or blockchain plugins in the repository?

No. According to the source analysis of anthropics/claude-plugins-community, the TRES Finance plugin is the sole community-contributed plugin targeting finance and blockchain applications. The repository's .claude-plugin/marketplace.json lists only this entry for financial use cases.

Do I need API keys to use the TRES Finance plugin?

The base plugin functions without external API keys. However, the tres-asset-balance-validation skill requires a DeBank API key configured via the DEBANK_API_KEY field in userConfig (defined in .claude-plugin/plugin.json) to perform on-chain balance comparisons.

What blockchains does the plugin support?

The plugin supports all blockchains indexed by TRES Finance, including Ethereum, Polygon, and other EVM-compatible chains. Specific blockchain availability can be configured via the tres-settings-management skill, which modifies platform-level sync filters and chain settings in the TRES Finance backend.
