Chart Library — Market-state research
io.github.grahammccain/chart-library in the official MCP registry.
Endpoint https://chartlibrary.io/mcp. Source: github.com/grahammccain/chart-library-mcp.
The registry describes it as: Market memory for AI: historical states, published studies and source evidence.
We read its 14 tools on 2026-10-26. Nothing in them matched our tool-poisoning rules. It also sets server instructions, text a client puts in front of the model on connect; those were read too.
A clean read means these rules found nothing, not that the server is harmless. A server can change its tools at any time, which is why the index reads it again every week.
Tools it advertises
get_company_file get_company_status get_company_revisions compare_company_revisions run_company_scenario check_company_forecasts compare_company_history get_company_watchlist list_coverage market_state daily_note research_quality search_research read_research

[](https://lazaretto.dev/mcp-registry/io-github-grahammccain-chart-library)How this was checked
Lazaretto connects to the endpoint the way any MCP client does, asks the server to introduce itself and list its tools, and reads every name, description, parameter schema and server instruction for tool poisoning: hidden directive blocks, orders to read local secrets, parameters built to carry secrets or the conversation out, orders that redirect another server's tools, and invisible characters. It never calls a tool. What we found across the registry.
To run the same check every time Claude Code adds a server, install the free lazaretto-guard plugin. Browse every server in the index.
