Simplefunctions MCP server

Simplefunctions is an MCP server with 108 tools an agent can call, among them add_position, augment_tree, batch_markets. It answers at https://simplefunctions.dev/api/mcp/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 24 October 2026, succeeded.

Description as the publisher wrote it.

The 108 tools Simplefunctions offers

ToolWhat it does
add_positionRecord a new position in a thesis for tracking. Use after an intent fills or a manual trade.
Inputs: thesisId, apiKey, venue, externalMarketId, marketTitle, direction
augment_treeAdvanced: Merge suggested causal tree nodes from evaluations into the tree (append-only).
Inputs: thesisId, apiKey, dryRun
batch_marketsFetch many markets at once by ticker list. Cheaper than calling get_market_detail in a loop.
Inputs: tickers, depth
browse_public_skillsBrowse public skills from the community. Free-tier and rate-limited. Filter by category, search, or sort by popularity.
Inputs: category, q, sort
cancel_intentCancel an active intent. Stops trigger evaluation and prevents execution.
Inputs: apiKey, intentId
close_positionDelete a position record from a thesis.
Inputs: thesisId, positionId, apiKey
configure_heartbeatConfigure the 24/7 heartbeat engine: news scan interval, X scan interval, LLM model tier, monthly budget, runtime pause/resume, and closed-loop intent creation. Agent can speed up monitoring during high volatility or slow down to save budge
Inputs: thesisId, apiKey, newsIntervalMin, xIntervalMin, evalModelTier, monthlyBudgetUsd
create_intentDeclare an execution intent: "buy X when condition Y, expire at Z." Intents are the single gateway for all order execution. The local runtime daemon evaluates triggers and executes via user's Kalshi/Polymarket keys.
Inputs: apiKey, action, venue, marketId, marketTitle, direction
create_skillCreate a custom agent skill — a reusable prompt/workflow that can be triggered via slash command.
Inputs: apiKey, name, trigger, description, prompt, category
create_strategySet up automated trading: define entry price, stop loss, take profit, and LLM-evaluated soft conditions. The heartbeat engine checks conditions every 15 min and executes when met.
Inputs: thesisId, apiKey, marketId, market, direction, horizon
create_thesisCreate a new prediction market thesis from a TESTABLE CLAIM — a statement that can be verified true or false at a future time. GOOD: "Bitcoin closes 2026 above $50,000". BAD: "High conviction due to large price gap" (that is reasoning, not
Inputs: apiKey, thesis, sync
enrich_contentCross-reference any text with thousands of prediction market contracts. Paste content + topics, get divergence analysis: where sentiment disagrees with market prices. No auth, no Firecrawl needed. Demo/trial entry point.
Inputs: content, topics, model, includeIndex
explore_publicBrowse public theses from other users. Free-tier and rate-limited. Pass a slug to get details, or omit to list all.
Inputs: slug
explore_thesesBrowse public theses (alias of explore_public). Pass slug to get one, omit to list.
Inputs: slug
fork_skillFork a public skill into your collection. No slug needed — just the skill ID.
Inputs: apiKey, skillId
fork_thesisFork a thesis. Two modes: (1) Clone — call with just idOrSlug to copy a PUBLIC thesis verbatim into your collection. (2) Evolve — call with newRawThesis to split a thesis you own into a new analytical frame for the same market sector; the p
Inputs: apiKey, idOrSlug, newRawThesis, newTitle, reason, inheritEdgeMarketIds
get_agent_guideRuntime playbook for agents: step-by-step workflows for query / monitor / integrate intents. Use when an agent is lost or needs onboarding.
Inputs: intent, q
get_answerPre-computed answer card for a probability question (the same data that powers /answer/{slug}). Returns probability, confidence, and citations.
Inputs: slug
get_balanceAdvanced: Kalshi account balance and portfolio value.
Inputs: apiKey
get_briefingTopic-scoped briefing: short narrative + relevant markets + prior moves + key dates. Reusable as a callable /briefing card.
Inputs: topic, window
get_calendarUpcoming dated events that drive prediction markets: FOMC, CPI release, election dates, sports finals. Returns date, topic, and linked tickers.
Inputs: days, category
get_calibrationSimpleFunctions calibration: Brier scores, hit rates by edge bucket, category breakdown, drift alerts. Measured against resolved/settled markets.
Inputs: category, period
get_changesMarket change events since a timestamp: new contracts, price moves, removed contracts. Used by the live feed and agent context refreshers.
Inputs: since, q, type
get_changes_deltaPer-thesis change delta since a timestamp — what evolved on this thesis (signals consumed, edges updated, confidence moves).
Inputs: thesisId, apiKey, since
get_congress_memberGet a single Congress member by bioguide ID.
Inputs: id
get_contagionConnected-market signals: contracts that historically co-move with the input topic but have diverged in the current window. Surfaces "this market should have moved but didn't" trades.
Inputs: topic, window
get_contextSTART HERE. Global market snapshot: top edges (mispriced contracts), price movers, highlights, traditional markets — live exchange data updated every 15 min. With thesisId + apiKey: thesis-specific context including causal tree, edges with
Inputs: thesisId, apiKey
get_economic_anchorsMacro/economic anchors from FRED: latest values, percentile vs history, crosswalk to relevant prediction markets. For grounding macro theses.
Inputs: category, series
get_edgesTop mispriced markets across all theses, ranked by edge size. Shows where your model disagrees with the market. No auth = public thesis edges. Auth = private + public.
Inputs: apiKey, limit, minEdge, venue
get_evaluation_historyConfidence trajectory over time — daily aggregated evaluations for a thesis. Use to analyze trends, detect convergence/divergence.
Inputs: thesisId, apiKey
get_feedCross-thesis evaluation feed: every evaluation across all your theses, ordered descending. Powers `sf feed` CLI.
Inputs: apiKey, hours, limit
get_fillsAdvanced: Recent trade fills on Kalshi.
Inputs: apiKey, ticker
get_forecastAdvanced: P50/P75/P90 percentile distribution for a Kalshi event — shows how market consensus shifted over time.
Inputs: eventTicker, days, apiKey
get_glossary_termGet a single glossary term with full definition and links.
Inputs: slug
get_heartbeat_configGet heartbeat config + monthly cost summary for a thesis (alias of get_heartbeat_status).
Inputs: thesisId, apiKey
get_heartbeat_statusGet heartbeat config + this month's cost summary for a thesis. See news/X scan intervals, model tier, budget usage.
Inputs: thesisId, apiKey
get_highlightsEditorial highlights for the day: top movers, divergences, fresh contagion, freshly-resolved markets. Curated summary view.
get_index_historyHistorical SimpleFunctions Index snapshots. Pre-computed every 15 minutes, stored since v2 launch (2026-04-09). For charting trends.
Inputs: days
get_legislationGet bill detail with prediction-market cross-reference (alias of legislation).
Inputs: billId
get_market_detailGet full detail for a single market: price, volume, indicators, regime label, history pointer, cross-venue counterpart. Lower-level than inspect_ticker — raw JSON only.
Inputs: ticker, depth
