• bls_dataframe_query

  bls-labor-mcp-server

  Run a single-statement SELECT against the canvas dataframes registered by bls_get_series. Read-only: writes, DDL, DROP, COPY, PRAGMA, ATTACH, and external-file table functions are rejected. System catalogs (information_schema, pg_catalog, sqlite_master, duckdb_*) are denied at the bridge layer — use bls_dataframe_describe to list available dataframes. Supports JOINs, aggregates, window functions, and CTEs. Optional register_as persists the result as a new dataframe with a fresh TTL for chained analysis. Canvas SQL operations consume zero BLS API quota. Requires CANVAS_PROVIDER_TYPE=duckdb.

• calculate_pace_layer_drag

  aibvf-mcp

  Quantify the annual EUR cost of an AI ambition outrunning the operating model: queues, hand-offs and slow decisions that prevent the organisation capturing the value already assumed in the case. CALL THIS when the user needs the cost of waiting for the organisation to change, or when a Fix plan needs a cost-of-waiting figure. Do not use it to score an AI initiative, estimate the implementation cost, or calculate a process saving: use score_initiative for the investment verdict, diagnose_process for a running process, and recommend_improvements for the change plan. revenue_eur sets the absolute EUR range; ai_tier and readiness together set the drag rate and pace_gap, so gen3 in a siloed organisation costs more than gen1 in an agile one. industry is accepted for a consistent interface and defaults to universal, but does not change this calculation yet. Returns a low/high EUR range, drag rate, pace-gap severity, drivers and source. Pure deterministic calculation — no network, auth, or side effects.

• exponent_calc

  calc.engineer

  Compute the result of raising a base to an exponent (base^exponent). Handles positive and negative exponents, fractional exponents, and zero. Returns the numeric result and a scientific notation string for very large or very small results. Useful for compound interest calculations, exponential growth/decay models, physics power laws, and combinatorics. The inverse of log_calc; chain with scientific_notation for formatted display of extreme values.

• get_risk_assessment

  Crank Protocol

  Combined regime + risk-guard calculation for a strategy on an asset (read-only). Folds the detected market regime together with the safe-default risk guards (position / exposure / single-loss / drawdown / daily-loss limits) into one deterministic output: a rules-based direction, a conviction-weighted position size already capped to the position guard (in both percent-of-equity and USD notional against ``equity``), a per-regime action note, and the full guard set. strategy_type is one of the 16 Crank strategy types; asset is a token mint; timeframe one of 1m/5m/15m/1h/4h/1d. A mechanical, non-personalised calculation you choose whether to act on (DYOR) -- not financial advice, not a recommendation, and not a managed account. No wallet, no fee. Workflow: RISK step -- after backtest_strategy, before execution. The returned suggested_size_usd caps the order in the execute phase; do NOT exceed it. Check asset_classification first (equity -> per-execution confirm). See get_trading_workflow.

• find_methodology

  OpenArx

  Find methodology approaches for a specific research task. Returns structured method-level results (not raw chunks): method name, key idea, dataset used, performance metric. Filters by task domain, dataset, metric. Built on LLM-classified contentType=methodology chunks combined with benchmark results JOIN. Use this instead of `search` when you want HOW researchers approach a problem rather than 10 papers about it. Note: surfaces any chunk classified as methodology, including ones where the task is mentioned only as a toy example. Filter by category (e.g. cs.CV for image tasks) to narrow scope. This searches EXISTING papers for methods others have published (literature search) — it is NOT a guide for conducting your own research: for a step-by-step scientific method tailored to your own research question, start with the `methodist` door.

• check_servicing

  Arthr — Australian home loans

  Run a REAL serviceability calculation across a panel of Australian lenders and get back, per lender, how much they would lend, whether they would lend at all, the rate they'd assess at, and — where they decline — why. This is not an estimate: it is the same calculation a broker runs. Use it once you have income, monthly living costs and a property value; prefer estimate_borrowing_power before that, for a fast rough figure. It is the only tool here that models HECS/HELP debt, and the only one that can tell you a lender says no. It takes seconds rather than milliseconds, so call it when the answer matters, not to explore.

• eia_dataframe_query

  eia-energy-mcp-server

  Run a single-statement SELECT against canvas dataframes registered by eia_query_route calls that passed stage: true — a query that staged nothing leaves no table to select from. Standard DuckDB SQL — joins, aggregates, window functions, CTEs all supported. Reference dataframes by the df_<id> handles returned by eia_query_route or listed by eia_dataframe_describe. Read-only: writes, DDL, DROP, COPY, PRAGMA, ATTACH, and external-file table functions are rejected. System catalogs (information_schema, pg_catalog, sqlite_master, duckdb_*) are denied. EIA data values are VARCHAR — use CAST(col AS DOUBLE) for arithmetic and aggregation. Optional register_as chains results as a new dataframe with a fresh expiry. Every dataframe named in the statement has its expiry extended by the query.

• faostat_dataframe_query

  faostat-mcp-server

  Run a single-statement SELECT against the canvas tables staged by faostat_query_observations and faostat_commodity_profile (table names look like faostat_xxxxxxxx). Use this for cross-country and cross-item aggregation, GROUP BY rankings, joins, and time-series analysis over the full result set the inline preview only sampled. Standard DuckDB SQL — joins, aggregates, window functions, CTEs all work. Read-only: writes, DDL, DROP, COPY, PRAGMA, ATTACH, and external-file table functions are rejected; system catalogs (information_schema, sqlite_master, duckdb_*) are denied — list staged tables via faostat_dataframe_describe. Every row carries its data-quality `flag` — commonly A=Official, B=time-series break, E=Estimated, I=Imputed, M=Missing (value cannot exist), T=Unofficial, X=from an international organization, plus others FAOSTAT defines per domain — keep it in projections, treat any unrecognized flag as informational, and never assume it is official.

• financial_calculator

  Inferventis — Financial Data, News & Web MCP

  Performs precise financial calculations across six calculation types entirely locally with no external API dependency. compound_interest computes the final value and total interest earned on a principal over time at a given annual rate. loan_repayment calculates the monthly payment, total repayable amount, and total interest for a mortgage or loan given the principal, annual rate, and term in months. roi returns return on investment as a percentage and absolute profit or loss, with optional annualised ROI when a holding period is provided. present_value discounts a future cash amount back to its current value using a discount rate. future_value projects a present amount forward at a compounding annual rate. break_even finds the unit volume and revenue at which fixed and variable costs are fully covered by sales. Use this tool when an agent needs to perform any structured financial calculation — loan affordability, investment return, discounted cash flow, or cost analysis. Prefer financial_calculator_lite when only the single headline result is needed rather than a full structured breakdown. Do not use this tool to fetch live market prices or exchange rates — use stock_quote for stock prices, crypto_price for cryptocurrency prices, or currency_convert for FX rates.

• financial_calculator_lite

  Inferventis — Financial Data, News & Web MCP

  Performs common financial calculations locally with no external API dependency. Supports compound interest, loan repayment, return on investment (ROI), present value, future value, and break-even analysis. Returns a single numeric result for the requested calculation type. This is a lightweight variant of financial_calculator — it returns only the result number rather than a full structured breakdown (monthly payment, total interest, annualised ROI, etc.). Use financial_calculator_lite when only the headline figure is needed. Prefer financial_calculator when the agent needs a full breakdown, multiple sub-values, or labelled output fields for compound interest earned, total repayable, or annualised returns. Neither this tool nor financial_calculator fetches live market data — for live prices use stock_quote, crypto_price, or currency_convert.
