What is trading-mcp-server CLAUDE.md?

A set of project instructions for building trading-mcp-server, a Python package that provides guarded tools for Indian stock-market data, simulation, and broker actions. It defines where code belongs and which modules may access the real broker.

Use it when adding or modifying services, MCP tools, broker integration, configuration, storage, or server wiring in the trading-mcp-server repository.

It gives coding agents clear boundaries for changing the package without breaking its structure or weakening the safety layer around real orders. It also prevents the package from depending on a separate trading workspace.

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	$0.01055	$0.01055

Security

Grade A, and why

trading-mcp-server 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 8d 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.

Project context

This repo is a standalone, pip-installable Python package that implements a local MCP with safe trading tools (NSE / Angel One). It is consumed by trading workspaces (e.g. the sibling TradingAgent repo) but must never depend on them. The agent using the tools lives elsewhere — this package only provides data, validation, simulation, and a guarded broker layer.

Package structure rules

src/ layout, import package trading_mcp_server, distribution name trading-mcp-server. Do not break this naming or move out of src/.
server.py only wires things together (create_server()); logic lives in services/, tool registration in tools/ (one module per category, each exposing register(mcp)), MCP resources/prompts in their packages.
broker/smartapi_adapter.py is the ONLY module that talks to the real broker, and services/broker_service.py is the ONLY caller of its order methods. Keep it that way — that's what makes the safety layer auditable.
All filesystem state goes under get_storage_dir(); all config through config.get_config(). Both resolve from TRADING_MCP_HOME (or cwd). Never hardcode a repo path, user path, or absolute path.
Heavy/optional imports (SmartApi, bs4) stay lazy so paper-mode users and tests run without the [broker,scanners] extras.

MCP tool design rules

Tools return plain JSON-serializable dicts; errors as {"error": ...} via tools/_common.make_tool — never let raw tracebacks reach the agent.
Docstrings are the agent-facing contract: state what the tool does, its enums (e.g. timeframes), and any safety behavior.
All order placement goes through the single place_order tool → broker_service.place_order, which calls validate_order and routes by EXECUTION_MODE. Never add a tool that places orders by another path.
Tools must never return secrets; config goes out via to_safe_dict() only.
Logs go to stderr (utils/logger.py); stdout belongs to the MCP transport.

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.
