tokenburnmarket

Connect your machine to tokenburnmarket, sync what your coding agents burned, and trade the markets from inside the agent you are already talking to.

Nothing leaves your machine except token counts, cost, and hashes of message identifiers. No prompts, no file names, no project paths.

Connect

npx tokenburnmarket connect

It prints a short code and a URL. Approve it in the browser and this machine is bound to your account, then it runs the first sync and prints where to see yourself. The private key it generates never leaves the machine.

Keep it synced

claude mcp add tokenburnmarket -- npx -y tokenburnmarket mcp

That is the whole of it for Claude Code. The MCP server syncs itself every time the agent starts it, skipping if the last one was under ten minutes ago, and gives the agent the trading tools below. Codex gets the same from ~/.codex/config.toml:

[mcp_servers.tokenburnmarket]
command = "npx"
args = ["-y", "tokenburnmarket", "mcp"]

On a machine that never opens an agent, run a daemon instead. It is a foreground loop, one per machine, held by a lock file.

npx tokenburnmarket daemon --interval 15m
npx tokenburnmarket daemon install

daemon install prints the launchd job or the systemd user unit for this machine, pointing at this node and this script. It prints; it never writes.

Sync by hand

npx tokenburnmarket sync            # the days since the last sync
npx tokenburnmarket sync --since 7  # the last seven days
npx tokenburnmarket sync --dry-run  # what would go, without sending it
npx tokenburnmarket status          # what is stored on this machine

sync is safe to run whenever. A sync you run yourself is never skipped.

MCP tools

Five tools:

| tool | what it does | | --- | --- | | sync_usage | uploads this machine's usage and reports what the server made of it | | my_stats | today, this week and this month of spend and tokens, credits, trust | | my_communities | the communities you belong to | | list_markets | open markets you can trade, with the price of every outcome | | place_bet | quotes a trade, and places it only with confirm: true |

place_bet never spends without confirm: true. Called without it, it prices the trade against the live book, writes nothing, and returns the cost, the average price and where the price would land, so the person can decide. Prices move, so a quote is an offer, not a promise: the server re-prices under a lock and refuses a fill that drifted too far.

Credits are play money. A winning share pays 1 credit.

Environment

| variable | what it does | | --- | --- | | TBM_SERVER | the server to talk to, same as --server | | TBM_CCUSAGE | a local ccusage command to run instead of npx -y ccusage@latest |

Config lives in the platform config directory: ~/Library/Application Support/tokenburnmarket on macOS, %APPDATA%\tokenburnmarket on Windows, $XDG_CONFIG_HOME/tokenburnmarket elsewhere. It holds a device token and a private key, and is written owner-only.

npx tokenburnmarket --help lists every command.

Releasing

cd packages/cli
npm publish

prepublishOnly runs check, test and build first. Bump version in package.json before, and npm pack --dry-run prints what would ship.
