Funda AI Skill
Funda AI exposes two complementary surfaces backed by the same data:
Surface
Best for
Auth
Output
MCP agent_chat at https://funda.ai/api/mcp
Research, analysis, synthesis
OAuth (auto via claude mcp add)
Synthesized text with disclaimer
REST /v1/* at https://api.funda.ai
Raw structured data
FUNDA_API_KEY Bearer
JSON
Both require an active Funda AI subscription.
Step 1: Decide Which Surface
User wants
Surface
DCF / comps walkthrough, sector view, transcript synthesis, company primer
MCP
Earnings preview/recap with judgment, beat-miss decomposition, narrative framing
MCP
Real-time or intraday quote, EOD price history
REST
Raw options chain snapshot, greeks, GEX time series
REST
Specific line item from a financial statement (single number, JSON)
REST
13F filings, insider trades, congressional trades as rows
REST
News with structured sentiment / event timeline (JSON)
REST
Bulk dataset downloads
REST
AI-company hiring signals (OpenAI, Anthropic, Google, xAI)
REST
Default to MCP for ambiguous research-style questions. Use REST when
the user wants machine-readable structured data — or when the MCP refuses
(real-time prices, raw quotes).
The MCP also refuses buy/sell calls, price targets, personalized
portfolio advice, tax/legal advice, and trade execution. Those are out of
scope for both surfaces — decline politely and don't fall through to REST
hoping for a different answer.
Step 2: MCP Flow (Research)
2a. Verify the MCP is connected
!`claude mcp list 2>/dev/null | grep -iE "^funda:" || echo "FUNDA_MCP_NOT_CONNECTED"`
A line starting with funda: → registered. The tool is callable as mcp__funda__agent_chat. Continue.
FUNDA_MCP_NOT_CONNECTED → ask the user to install:
claude mcp add --transport http funda https://funda.ai/api/mcp
A browser tab opens for OAuth approval (1-hour token + 30-day refresh, auto-managed). The Claude Code session may need to be restarted before the tool registers.
2b. Frame the question
agent_chat is a fresh research turn with no cross-call memory — bake
the ticker, time horizon, and assumptions into the question text itself.
User wants
Question shape
Earnings preview
"Preview MSFT's Q3 print Thursday — segment trends, where consensus is aggressive/conservative, beat/miss pattern."
Earnings recap
"Walk through NVDA Q2: beat/miss by segment, guide vs consensus, transcript Q&A on data-center demand."
Sector deep-dive
"Summarize the 2026 hyperscaler capex cycle — spending tiers by name, supplier exposure, gross-margin implications."
Supply chain
"Map TSMC's customer concentration and N2 ramp risks — top three exposures by revenue."
Filing summary
"Diff the new risk factors in PLTR's latest 10-K versus the prior year."
DCF
"Walk through a DCF for NVDA assuming 25% data-center growth, 10% terminal margin, 9% WACC — surface the sensitivity table."
Macro
"Where in the Dalio long-term debt cycle is the US, and what does that imply for duration positioning?"
Ownership
"Has institutional ownership of CRWD shifted in the latest 13F filings — net buyers vs sellers?"
If the user gave only a ticker, ask one clarifying question to scope the
turn (preview? recap? primer? DCF?) before calling — vague questions burn
a turn and return vague answers.
If the user is following up on a prior Funda response, quote the relevant
paragraph back inside the new question; the agent has no memory of prior
calls.
For more example questions per topic, see references/research-topics.md.
2c. Call the tool
mcp__funda__agent_chat(question: "<full research question>")
Typical run is 15–60 seconds; the server streams progress notifications
throughout, so the client doesn't time out.
Response shape:
content[0].text — answer prefixed with [Funda research output — fundamental analysis, informational only…]. Keep the prefix.
_meta["funda.io/conversation_id"] — UUID. The in-app history page is https://funda.ai/agent-chat?c=<id> (the /agent-chat route redirects to /agent-chat-v2?c=<id>).
_meta["funda.io/timed_out"] — true if the agent hit its run budget. Answer is partial; offer to retry with a tighter scope.
If the call returns 403 subscription_required, the MCP is registered
but the account isn't subscribed — direct the user to https://funda.ai
to activate.
Each call costs a research turn. Don't speculatively re-call with a
rephrased question if the first answer was reasonable.
Step 3: REST Flow (Raw Data)
3a. Resolve FUNDA_API_KEY
The skill resolves FUNDA_API_KEY in this order:
FUNDA_API_KEY environment variable
FUNDA_API_KEY in .env in the current directory
FUNDA_API_KEY in .env at the git repo root (so a worktree inherits the key from the main checkout)
!`if [ -n "$FUNDA_API_KEY" ]; then echo "KEY_FROM_ENV_VAR"; elif [ -f .env ] && grep -qE "^FUNDA_API_KEY=" .env; then echo "KEY_FROM_LOCAL_DOTENV:$(pwd)/.env"; else GIT_COMMON=$(git rev-parse --path-format=absolute --git-common-dir 2>/dev/null); if [ -n "$GIT_COMMON" ]; then ROOT=$(dirname "$GIT_COMMON"); if [ -f "$ROOT/.env" ] && grep -qE "^FUNDA_API_KEY=" "$ROOT/.env"; then echo "KEY_FROM_ROOT_DOTENV:$ROOT/.env"; else echo "KEY_NOT_SET"; fi; else echo "KEY_NOT_SET"; fi; fi`
Then act on the result:
KEY_FROM_ENV_VAR — use $FUNDA_API_KEY directly in curl calls.
KEY_FROM_LOCAL_DOTENV:<path> / KEY_FROM_ROOT_DOTENV:<path> — load once before calling:
export FUNDA_API_KEY=$(grep -E "^FUNDA_API_KEY=" <path> | head -1 | cut -d= -f2- | sed 's/^["'\'']//;s/["'\'']$//')
KEY_NOT_SET — ask the user for their key. They can either export FUNDA_API_KEY="..." or add FUNDA_API_KEY=... to .env at the repo root (preferred for worktrees).
3b. Find the right endpoint
Match the user's request to a category and read the corresponding
reference file for full parameters and response schemas.

3c. Call the endpoint
curl -s -H "Authorization: Bearer $FUNDA_API_KEY" \
"https://api.funda.ai/v1/<endpoint>?<params>" | python3 -m json.tool
All responses are {"code": "0", "message": "", "data": ...}. A non-zero
code is an error — read message.
List endpoints paginate: {"items": [...], "page": 0, "page_size": 20, "next_page": 1, "total_count": N}. Pages are 0-based; next_page is -1 when exhausted.
For broad ticker overviews ("tell me about AAPL"), combine a few REST
calls: /v1/company-profile for sector/CEO/mcap/price + /v1/financial-statements?type=key-metrics-ttm + /v1/analyst?type=price-target-summary.
Step 4: Respond to the User
For MCP synthesis: surface with structure (tables, bullets, headings) — don't dump the raw blob. Preserve the Funda disclaimer; never repackage analysis as a recommendation, price target, or trade signal.
For MCP responses, cite https://funda.ai/agent-chat?c={conversation_id} so the user can inspect the agent's full timeline.
For REST responses, format numbers cleanly (prices to 2 decimals, ratios to 2-4, large numbers with commas or abbreviations like $2.8T). Use tables for comparative data; summarize trends rather than dumping time series.
For DCF / valuation work, surface the assumptions Funda used so the user can adjust them.
Note the source: "Funda AI" (whether MCP or REST).
Never provide trading recommendations — present the data and let the user draw conclusions.
