| Client coverage note | Local stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server. | |
| Access and data | ||
| Authentication | The hosted endpoint uses an OAuth consent flow that asks for a Financial Modeling Prep API key on first use. Local stdio uses FINANCIAL_MODELING_PREP_API_KEY or FINANCETOOLKIT_ENV_FILE; inline configuration takes precedence when both are present. Use a dedicated key and remove the MCP entry, local secret, and publisher authorization when access is no longer needed. | Local mode uses PAYPAL_ACCESS_TOKEN and PAYPAL_ENVIRONMENT. Remote mode supports PayPal login and consent or token authorization; PayPal publishes separate Sandbox and Production endpoints. |
| Cost | The MIT-licensed Finance Toolkit package and MCP documentation list no separate MCP usage fee. The documented Financial Modeling Prep free plan is limited to 250 requests per day, five years of data, and US-listed companies; premium data and some metrics require a paid FMP plan, and normal hosting, client, and model costs may also apply. | The MCP package is publicly available. Normal PayPal account, transaction, product, API, and merchant-service fees or limits remain applicable. |
| Permissions | The documented MCP tools retrieve company, market, risk, model, and economic data and calculate financial metrics with the operator's Financial Modeling Prep key. The documented surface does not include brokerage or trade execution. Local setup writes client configuration, and the local server writes a SQLite result cache in the configured Finance Toolkit data directory. | Capabilities depend on enabled tools and the PayPal credential and can include reads and mutations across invoices, orders, subscriptions, disputes, shipments, transaction details, and related merchant resources. |
| Data handling | The hosted service receives the Financial Modeling Prep API key through its OAuth consent page, remembers it, fetches live financial data, and returns results to the connected MCP client; hosted retention and logging are not documented. Local mode reads the key from inline environment configuration or a local environment file and caches result DataFrames in SQLite with a documented default 600-second TTL. Finance Toolkit may fall back from Financial Modeling Prep to Yahoo Finance unless the source is enforced. | The local MCP process sends merchant, customer, payment, and task data to PayPal APIs and returns results to the MCP client. The hosted option processes requests through PayPal's remote MCP service. |
| Limitations | ||
| Tradeoffs |
|
|
| Risk context | Protect the Financial Modeling Prep API key, prefer a dedicated credential, and independently verify material financial output. The publisher disclaims responsibility for upstream data accuracy and documents an automatic Yahoo Finance fallback unless a source is enforced. Hosted key retention and logging are not documented, while local mode leaves configuration and cached financial results on disk. | Production access can create financial loss or customer-facing changes and can disclose transaction data. Start with Sandbox, keep credentials out of files and history, minimize tools, and require approval for every mutation. |
