Pierce vs. Shibui: Claude Desktop plumbing vs. a finished research agent
If the job is connecting Claude Desktop to market data, Shibui is the right tool. If the job is research you can defend — skills, tools, a self-checking loop — Pierce is the hosted agent. Raw data into a generic chat is not the same architecture.
Shibui is an MCP server and data API. It feeds financial data into Claude Desktop or a custom agent you assemble. It is infrastructure, not a research product with an opinionated loop.
How Pierce Finance and Shibui Finance approach the research workflow.

| What you are buying | Hosted web agent with UI, 44 skills, and a quant engine already assembled. | MCP server and APIs that attach financial data to an external model. | Winner: Pierce |

| Setup | Browser. No local stack. | Keys, config files, and a client you maintain. | Winner: Pierce |

Where Pierce should not be used relative to Shibui Finance:
Shibui charges for MCP and API usage so you can wire data into your own LLM client. Pierce is pay-as-you-go, with higher-volume plans and professional plans for CFAs and RIAs.
“Screen semiconductors with ROIC over 20 percent and debt-to-equity under 0.5, then run a ten-year DCF on NVDA”
Use Shibui if your goal is to feed data into Claude Desktop. Use Pierce if you want a finished research agent with skills, tools, and a self-checking loop you did not have to architect.
No. Pierce is a web application for analysts. Shibui assumes you are comfortable configuring an MCP client.
General chatbots are not loaded with Pierce’s financial skills, do not run a check-and-correct loop, and will still guess at multi-step math. That is the gap Shibui cannot close by supplying data alone.
