get_context | Returns the universal context-setting primer for Hemrock models, plus an optional template-specific addendum. Always run this first before any other prompts. params: template_name |
get_prompts | Returns task-specific Layer 2 prompts for a given template and task type. These are ready-to-use prompts for common modeling tasks. params: template_name*, task_type |
get_checks | Returns Layer 3 sanity-check and validation prompts — the 'where AI gets financial modeling wrong' guidance. Use these to audit AI-generated work or catch common modeling errors. params: template_name* |
get_best_practices | Returns Hemrock's financial modeling best practices and design principles for a given topic. Useful as background context for AI interactions. params: topic |
list_concepts | Lists Hemrock financial-modeling concept docs — the methodology behind the math (exit waterfalls, anti-dilution, convertibles, cohorts, circular references, unit economics, and more). Returns a compact index of slugs, titles, and descriptions. Optionally filter by template_name or tag. Call get_concept to read the full text of any entry. params: template_name, tag |
get_concept | Returns the full text of a single Hemrock concept doc by slug. Use this to learn how a financial-modeling calculation actually works before building or auditing it. Get valid slugs from list_concepts. params: slug* |
list_models | Lists the hosted Hemrock calculation engines (cap table, exit waterfall, fund economics), what each computes, and its price and checkout link. Free and needs no sign-in, so call it when the user asks what Hemrock can calculate or what it costs. params: none |
get_access | Returns public access terms for an engine: product, annual price, billing period, annual allowance, and a customer checkout URL. This is informational and does not purchase or confirm account-specific access; use get_account_access for the authenticated account. params: model* |
get_account_access | Returns whether this connection is signed in, its annual product access and remaining calculations. Does not consume allowance. Call it before a compute tool if you are unsure the user can run one. If the result contains action_required (not signed in, no purchase, allowance used), relay it to the user with its links and offer to retry. Never skip the calculation silently. params: none |
get_account_usage | Returns signed-in usage history and endpoint/source breakdown. Does not consume allowance. If the result contains action_required (not signed in, no purchase, allowance used), relay it to the user with its links and offer to retry. Never skip the calculation silently. params: from, to |
cap_table_compute | Use whenever the user asks who owns what after a financing: founder splits, option pools, priced rounds, SAFEs and convertible notes converting, warrants, pro-rata, or dilution across several rounds. Takes the financing events in order and returns fully diluted ownership after each event plus the final cap table. Prefer this over doing the arithmetic yourself: SAFE and note conversion (pre- vs pos params: events*, idempotency_key |
exit_waterfall_compute | Use whenever the user asks what each holder gets at an exit, acquisition or liquidation: liquidation preferences, participating vs non-participating preferred, participation caps, seniority, whether a series converts, options and warrants in or out of the money. Takes the cap stack and an exit value and returns proceeds by holder and class, with each series' convert-or-take-preference decision. Pr params: exitValuation*, model*, idempotency_key |
fund_economics_compute | Use whenever the user asks how a venture fund's terms play out: fund size, management fees and step-downs, carry, investment period, recycling, reserves, deployment pace, and resulting net returns to LPs. Takes fund inputs (start from the defaults and change only what the user specifies) and returns lifetime capital, fees, investable capital and gross/net multiples (result), plus the fund over tim params: inputs*, features, granularity, firstCloseDate, format, fundName, idempotency_key |
list_saved_models | Lists the cap tables, exit waterfalls and fund models saved to the user's Hemrock account, plus fund models others have shared with them, newest first. Each has its kind, id, name, the user's role (owner, editor, viewer) and a url that opens it in the browser builder. Call this when the user mentions "my cap table", "my fund model" or a model by name, before building one from scratch. Free: uses n params: kind |
get_saved_model | Returns a saved model's contents in the shape the compute tools take: a cap table's events and options, a waterfall's model and saved exit, or a fund's inputs, the features switched on, and featuresSavedButOff (configured but switched off). Free: uses no calculations. Needs a signed-in connection. params: kind*, id* |
run_saved_model | Calculates a saved model as it stands, with the same engine as the browser builder: ownership after every event for a cap table, proceeds by holder for a waterfall (at the saved exit, or up to 10 exitValuations you pass), or a fund's lifetime totals plus the fund by year (granularity "quarter" or "none" to change that). For a fund, workbook true adds a 24-hour link to the live Excel workbook; that params: kind*, id*, exitValuations, granularity, workbook |
update_saved_model | Saves a change to a model in the user's account; the browser builder shows it the next time it opens. Send only the fields that change. Owners can change anything; invited editors of a fund model can change its inputs while the owner has access; viewers can't change anything. Tell the user what you changed, run the model to show the effect, and give them the url. Free: uses no calculations. Needs params: kind*, id*, name, events, model, options, inputs, features, cashFlows, fundName |
create_saved_model | Saves a new model to the user's account so they can open it in the browser builder and keep working on it. A fund starts from Hemrock's defaults with your inputs merged on; a cap table needs events; a waterfall needs a model and options.exitValuation. Use it when the user wants to keep a model you built in chat, and give them the url. Free: uses no calculations. Needs a signed-in connection. params: kind*, name, events, model, options, inputs, features, cashFlows, fundName |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
