Available tools 7

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

generate

generate_initiator_source

Generates generic Java source for a managed or standalone Fixie initiator.

generate_runtime_config

Generates a runtime configuration entry for a Fixie initiator.

parse

parse_fix_message

Use this tool whenever you see one raw FIX message string, typically starting with 8=FIX. The input may use pipe (|) or SOH separators. By default it returns only the human-readable hierarchical output. Set type=tags to return only the hierarchical FIX field/tag view.

parse_fix_messages

Use this tool whenever you see multiple raw FIX messages that need to be parsed in order. Each message typically starts with 8=FIX and may use pipe (|) or SOH separators. Returns ordered Onikora UFO, FFO, and optional sequence output.

initiator

get_initiator_recipe

Returns the recommended Fixie initiator pattern for market_data, order_entry, or quote_request.

runtime

get_runtime_config_template

Returns a JSON runtime configuration template for a Fixie initiator.

validate

validate_initiator_spec

Checks whether the initiator request has enough information to generate useful Fixie code.

Fixie MCP Server — questions

Answers built from our own checks of this server.

What can Fixie MCP Server do?

It exposes 7 tools, read directly from the server on our last check. Among them: generate_initiator_source, generate_runtime_config, get_initiator_recipe, get_runtime_config_template, parse_fix_message, parse_fix_messages and 1 more. 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 Fixie MCP Server mostly used for?

Its tools cluster around parse and generate. 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 Fixie MCP Server working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 256 ms. The bar chart above shows every period we have measured.

The registry lists Fixie MCP Server as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Fixie MCP Server?

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 Fixie MCP Server need an API key?

No. Fixie MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

Is Fixie MCP Server open source?

We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
