Five tools, all read-only

Upcoming company events for a US ticker, or the macro calendar and Fed meetings.

research_topic1 ACTION

Company context for the tickers a topic touches: name, sector, industry, exchange. It doesn't search the web; pair it with your assistant's own search.

Keys and limits

Try it without an account: 2 research actions a day (a rolling 24 hours). A developer key raises that to your plan's allowance (10 a day on a free account); the record tools never count. Send it as ALGOTHESIS_API_KEY.

  "command": "npx", "args": ["-y", "algothesis-mcp"],
  "env": { "ALGOTHESIS_API_KEY": "algo_dk_…" } } } }

Settings → Developer → Edit config, paste, restart Claude. Leave out "env" to try it without a key.

Headlines are ours: Story headlines and summaries are AlgoThesis's own, checked before tools may share them. Every story names its outlet and links to it.
Moves, not prices: Percentages between end-of-day closes: the first close after a story against the close before it. Data provided by Databento (end of day). Research information, not investment advice.
