What is wallet-budgetbakers-mcp CLAUDE.md?

Project instructions for a read-only connector to Wallet by BudgetBakers, a personal finance app. It retrieves financial data through ten read-only tools and does not change records.

Use it to run, install, type-check, or maintain a connector that reads accounts and other Wallet financial data.

It gives developers the setup commands and implementation details for safely reading budgeting data. Because the tools are read-only, it cannot create, edit, or delete financial entries.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00560	$0.00560
Opus 5	$0.00280	$0.00280
Sonnet 5	$0.00112	$0.00112
Haiku 4.5	$0.00056	$0.00056

Security

Grade A, and why

wallet-budgetbakers-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What This Is

Read-only MCP server for accessing Wallet by BudgetBakers financial data. Single-file Python project (server.py, ~460 lines) using the FastMCP framework. All 10 tools are GET-only — no write operations.

Commands

# Run the server
uv run server.py

# Install/sync dependencies
uv sync

# Type check
uv run pyright server.py

There are no tests configured.

Architecture

server.py — the entire application:

Lifespan (app_lifespan) — creates a shared httpx.AsyncClient with Bearer token auth from WALLET_API_TOKEN env var
_fetch() — single HTTP helper that all tools call. Appends agentHints=true, handles 429 rate limits and errors, returns formatted JSON strings
10 @mcp.tool() functions — thin wrappers that map tool parameters to API query params and call _fetch()

API base: https://rest.budgetbakers.com/wallet/v1/api

Tool parameter conventions:

snake_case Python params map to camelCase API params (e.g., account_id → accountId)
Text filters use prefixes: eq., contains., contains-i.
Range filters use prefixes: gte., lte. (combinable: gte.100,lte.500)
Pagination: limit (1-100) + offset
All tools return str (JSON)

Record types: recordType is income or expense only. Transfers are identified by transferId/transferAccountId fields in the response, not by recordType.

Date constraints (records): Max 370-day range per query. Default (no filter): last 3 months.

Rate limit: 500 requests/hour. The server returns structured JSON error on 429 with retry_after.

Dependencies

mcp[cli]>=1.2.0 — FastMCP server framework
httpx>=0.27.0 — async HTTP client
Python 3.11+, managed with uv

Setup

Requires WALLET_API_TOKEN env var (get from https://web.budgetbakers.com/settings/apiTokens, requires Premium). The .mcp.json file handles auto-discovery in Claude Code.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
