Overview

AI-generated overview

Lets an assistant look up, filter, and compare rule and fee data on 71 prop trading firms, with each figure's evidence state.

What you can do
Provides six read-only tools over FirmFax's independent dataset of prop trading firms. list_firms returns every firm slug and name; get_firm returns one firm's figures, each marked with whether evidence is held, and withholds a letter grade when the score range spans more than one band. find_firms matches firms against criteria and returns non-matching records separately under unknown, compare_firms puts two firms side by side without declaring a winner, get_rule_changes returns a dated change log newest first, and get_evidence returns the stored quote, source page, and reading date behind a figure.
When to use it
Useful when comparing prop trading firms' rules and fees, screening firms against criteria, or checking what changed and when. Also suited to verifying a specific figure, since each one can be traced to a stored quote and reading date.
Requirements
A remote endpoint at firmfax.com over streamable HTTP; no packages, environment variables, or headers are declared. No authentication is declared.
Before you install
The data is FirmFax's own reading of firm websites, and the change log mostly records FirmFax correcting its own data rather than firms changing rules, so read counts before describing industry activity. Missing fields are common: unmatched firms are returned under unknown, and absence of a record is not a tie or a win. Evidence rows marked contradicted, contradiction, or absent record what was read, not a published figure.

Installation

In SourceWeft

  1. Open FirmFax prop firm data in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.firmfax%2Fprop-firm-data/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

get_firm

One prop trading firm. Every figure states whether we hold evidence for it, and a firm whose score range spans more than one band carries no letter grade at all.

Parametersslugrequired

get_rule_changes

The dated record of what changed, newest first. Every entry states its KIND, and most of this tape is FirmFax correcting its own data rather than a firm changing its rules. Read counts before describing industry activity: a total taken across kinds overstates it.

Parameterskindsluglimitsince

get_evidence

The stored reading behind a figure: the verbatim quote, the page it came from, and the date we read it. Answers "we hold none" explicitly rather than returning an empty list. `outcome` is load-bearing: a `contradicted`, `contradiction` or `absent` row records what we read, not a figure we publish. Use get_firm for the published figure.

Parametersslugrequiredfield

find_firms

Firms matching every criterion given. A firm whose record does not carry a criterion is never counted as a match and never silently dropped: it is returned separately under unknown, with the field that could not be tested. Absence is common here, so read counts before treating the matched list as the answer.

compare_firms

Two firms side by side. Reports each figure with its evidence state and whether the pair is comparable at all: a field neither firm records is not a tie, and a field only one records is not a win. No per-field winner is declared, because the direction of "better" for several of these is a judgement the published scoring model already makes; each firm's grade is returned alongside so the verdict comes from that model rather than from this tool.

list_firms

Every firm slug and name. Carries no figures, so nothing here needs evidence.

Takes no parameters.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
