Octagon MCP

octagonai · MCP server

Octagon MCP connects your AI assistant to the Octagon Market Intelligence API for investment research. An orchestrating agent handles SEC filings, earnings call transcripts, stock and crypto data, news, press releases, ownership and holdings, while a deep research agent combines several sources and a prediction markets agent writes research reports and returns historical data. Search and read tools for the Octagon documentation work even before an API key is set up.

Written by ooruby from the README of octagon-mcp 1.2.0.

Not claimed by its maker. Is this yours? Prove it and answer the findings

Why it's useful

Your agent can answer investment questions from filings, earnings calls, market data and prediction market research in one place.

What you could do with it

  1. 1Ask for the main points of the latest 10-K for a company and what management said on its last earnings call.
  2. 2Put an investment question to the deep research agent and get one answer drawn from several sources.
  3. 3Request an updated research report on a prediction market, then pull its historical data.

Written from its documentation: what it says it can do, not what our checks found.

Maintenance

Not measured

No release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.

Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured

How far this has been checked

Static scanned

What it establishes
Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
What it does not
How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
Exactly what was read
Version 1.2.0, the file with digest sha512-KSBmIhMI2UgDRM7TndEQTgazTbixPFHtBuTLuKyAZd1I9sezgQEqBZQAHsaNNZ3Bo11nRlkjybxr46IB5Gob5A==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
Authentication
Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
How the rungs work

Adding it

Paste this into your client's MCP configuration.

{
  "mcpServers": {
    "octagon-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "octagon-mcp@1.2.0"
      ]
    }
  }
}

Or run it directly.

npx -y octagon-mcp@1.2.0

Pinned to 1.2.0, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.

The badge, if this is your listing

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
