spoken-alpha-mcp 0.1.0

MCP server for Spoken Alpha — earnings-call data and language signals API. Tools for ir-page lookup, earnings-calls history, and press-releases (scaffolded).

spoken-alpha-mcp

MCP (Model Context Protocol) server that exposes the Spoken Alpha public API as tools any Claude-using agent can call by name.

The server is a thin client over api.spokenalpha.com/v1/*. It does not bypass auth, expose internal endpoints, or add functionality beyond what the public API ships. Wrapping, not extending.

What it gives you

Three tools, one per Tier 1 endpoint in the public API reference:

Tool	Endpoint	Status in v1
get_ir_page	GET /v1/companies/{ticker}/ir-page	Live
get_earnings_calls	GET /v1/companies/{ticker}/earnings-calls	Live
get_press_releases	GET /v1/companies/{ticker}/press-releases	Scaffolded — 503 until structured ingest ships

All three accept a US ticker (AAPL, MSFT, BRK.B). get_earnings_calls also accepts limit, cursor, date_from, date_to, confirmed_only, plus client-side fiscal_year / fiscal_quarter filters.

Getting an API key

Spoken Alpha is in private beta. Email [e-mail] to request a key. Pricing tiers and the public listing are at spokenalpha.com/pricing. Set the raw key as SPOKEN_ALPHA_API_KEY — the server forwards it as Authorization: Bearer <key> on every request.

Install

Requires Python 3.11+.

pip install spoken-alpha-mcp
# or, after this package is published to the registry:
# uvx spoken-alpha-mcp

From a local checkout:

cd mcp/spoken-alpha-mcp
pip install -e .

Wire it into Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "spoken-alpha": {
      "command": "spoken-alpha-mcp",
      "env": {
        "SPOKEN_ALPHA_API_KEY": "sk_live_..."
      }
    }
  }
}

If spoken-alpha-mcp isn't on PATH, replace with the absolute install path or use python -m spoken_alpha_mcp.

Wire it into Claude Code

Per-project MCP server (in your repo's .mcp.json):

{
  "mcpServers": {
    "spoken-alpha": {
      "command": "spoken-alpha-mcp",
      "env": { "SPOKEN_ALPHA_API_KEY": "sk_live_..." }
    }
  }
}

Example session

You: Where's Apple's IR page, and when was their last earnings call?

Claude calls get_ir_page("AAPL") → returns
  { "ticker": "AAPL",
    "company_name": "Apple Inc.",
    "ir_page": { "url": "https://investor.apple.com/...", "validation_status": "valid", ... },
    "_self": "..." }

Claude calls get_earnings_calls("AAPL", limit=1) → returns
  { "ticker": "AAPL",
    "calls": [ { "id": "call_AAPL_2026Q2_earnings", "call_date": "2026-05-01", ... } ],
    "pagination": { "next_cursor": null, "has_more": false },
    "_self": "..." }

Claude: Apple's IR page is at investor.apple.com (validated). Their most
        recent earnings call was Q2 FY2026 on 2026-05-01.

Error handling

Every tool returns either a success payload or an error payload of the shape:

{
  "error": true,
  "code": "ticker_not_found",
  "message": "No company found for ticker.",
  "status_code": 404,
  "request_id": "8c3f1e2a-...",
  "documentation_url": "https://api.spokenalpha.com/docs/errors#ticker_not_found"
}

Codes you'll see in practice:

• unauthorized (401) — bad or missing SPOKEN_ALPHA_API_KEY.
• forbidden_for_tier (403) — your tier doesn't include this field/endpoint.
• ticker_not_found / ir_page_not_found (404) — company or IR URL missing.
• validation_error (422) — query param out of range.
• rate_limit_exceeded (429) — hourly/monthly cap; rate_limit_reset_at is the unix timestamp.
• data_not_yet_available (503) — for get_press_releases in v1; the payload carries planned_launch.
• timeout / network_error — transport failure before reaching the API.

Configuration

Env var	Default	Notes
SPOKEN_ALPHA_API_KEY	(required)	Raw bearer key from your dashboard.
SPOKEN_ALPHA_API_BASE_URL	https://api.spokenalpha.com/v1	Override for staging / local dev.

Development

cd mcp/spoken-alpha-mcp
python -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"

What this is NOT

• Not an MCP for our internal trading signals. The proprietary surface (per-speaker deviation, the LLM scorer composition, short_signal_score) is walled off in ADR-0031 — by the same rules, this MCP only exposes the public API.
• Not a richer client than the API itself. If a field isn't in the public API contract, it isn't in this MCP. New endpoints come through the API roadmap.
