Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

pulse

get_pulse

Get the current FinFam Pulse — FinFam's twice-daily money-news digest. Use this for "what's happening in finance / markets / the economy right now" questions instead of answering from memory. Returns a dated headline and paragraph, the overall mood, a finfam.app permalink, the external grounding sources, and the edition's story cards (each with its own article URL). Cite the permalink and the story URLs. Returns null when nothing is published yet. Args: period: 'today' for the latest daily read, 'week' for the running weekly read

search_pulse

Search past FinFam Pulse editions by topic (e.g. "Fed", "mortgage rates", "layoffs"). Matches both the editions' prose and their individual story cards. Each result is one dated edition with its headline, paragraph, permalink, sources, and the story cards that matched. Best match first, newest as the tiebreak. Args: query: Topic or keywords to match days: How many days back to search (default 30, max 365) limit: Maximum number of editions to return (default 5, max 20) category: Optional card category filter — one of markets, rates, housing, jobs, spending, debt, money_drama, human_interest, retirement, taxes

view

get_view_signature

Get the full input/output contract for a financial calculator. Returns field names, types, defaults, and hints so you know exactly what inputs to collect from the user before running a calculation. Args: owner_username: The view owner's username (from search results) viewname: The view's URL slug (from search results)

get_view_source

Get the source code/formulas of an open-source financial calculator. Only available for views that have been published as open-source. Returns the calculation logic as a readable TSV showing fields, types, defaults, and formulas. Args: owner_username: The view owner's username viewname: The view's URL slug

calculate

calculate_view

Run a financial calculation with the provided input values. Pass field values as a dict mapping field names to values. Use the types from get_view_signature: amount fields take numbers (e.g. 300000), percent fields take decimals (0.05 = 5%), count fields take integers, yesno fields take true/false. Args: owner_username: The view owner's username viewname: The view's URL slug inputs: Dict of field_name -> value for input fields

views

search_views

Search for financial calculators matching a question or topic. Args: query: Natural language search query (e.g. "should I rent or buy a house") limit: Maximum number of results to return (default 5, max 20)

FinFam Financial Calculators — questions

Answers built from our own checks of this server.

What can FinFam Financial Calculators do?

It exposes 6 tools, read directly from the server on our last check. Among them: calculate_view, get_pulse, get_view_signature, get_view_source, search_pulse, search_views. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is FinFam Financial Calculators mostly used for?

Its tools cluster around pulse and view. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is FinFam Financial Calculators working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 580 ms. The bar chart above shows every period we have measured.

How do I connect FinFam Financial Calculators?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does FinFam Financial Calculators need an API key?

No. FinFam Financial Calculators completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is FinFam Financial Calculators?

It answers our handshake in 580 ms on average, which is faster than 23% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
