go-mcp-server-financeiro

Provides a simple Model Context Protocol (MCP)-oriented server (implemented in Go) that lets clients register and list “financial tools”, query stock prices via the Alpha Vantage public API, and fetch server metadata via a /metadata endpoint.

Secret Handling

No client auth is described for the server endpoints; secrets for Alpha Vantage are expected via .env, which is a reasonable pattern, but transport/security requirements (TLS, CORS, headers), input validation, and logging redaction are not documented.

Error Recovery

Best When

You need a lightweight example/demo for MCP server structure and agent tool invocation backed by a public market data API.

Avoid When

You require fine-grained authorization, documented rate-limit/error semantics, idempotent write guarantees, or a production-grade reliability profile.

Use Cases

• Prototype an MCP-style tool registry for financial data actions
• Have an agent dynamically discover and invoke a stock price lookup tool
• Quick demo of integrating an agent-facing server with Alpha Vantage

Not For

• Production deployment requiring strong security controls and formal contracts
• Use cases that need strict compliance, audit logging, or robust operational guarantees
• High-scale trading/market data workloads beyond free-tier/public API limits

Interface

REST API

Yes

GraphQL

gRPC

MCP Server

Yes

SDK

Webhooks

Authentication

OAuth: No Scopes: No

The README shows API key usage only for Alpha Vantage via an .env file for the server itself. No client authentication/authorization mechanism is described for the server endpoints.

Pricing

Free tier: No

Requires CC: No

Alpha Vantage requires an API key and has its own pricing/free-tier model; the package itself does not describe pricing.

Idempotent

False

Retry Guidance

Not documented

Known Gotchas

⚠ Server rate limits and error responses are not documented; agents may need to implement conservative retries/backoff.
⚠ Tool registration appears dynamic, but behavior/constraints (duplicates, validation) are not described.
⚠ Alpha Vantage free-tier and API limits may affect availability/latency; the wrapper does not document how it handles throttling.

Alternatives

Use the Alpha Vantage API directly from your application with your own tool/agent wrapper Build a dedicated MCP server using a standard web framework plus OpenAPI and explicit auth/rate-limit handling Use another market data provider with official SDKs and documented usage limits
