Claude Code: ask. ### `ask_freight_analyst` - Nothing in its name or description says what it does, so it is counted as a write. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Ask FreightFA's AI freight analyst a question in plain language: lane rates, mode choice, capacity, fuel, carrier vetting, market news, or drafting an RFP. Answers cite their sources and can include a priced rate card. Pass session_id from a previous answer to continue the same conversation. Each question counts toward the account's monthly FreightFA allowance. ``` ### `calculate_margin` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Margin on a load from the buy rate (carrier cost) and sell rate (what the shipper pays): margin in dollars and percent of sell, the per-mile spread when miles are given, and the sell price needed to hit a target margin. Pure arithmetic; does not count toward the allowance. ``` ### `create_rate_alert` - The name "create_rate_alert" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create a lane rate alert for the signed-in user. Notifies them when the benchmark crosses the threshold. ``` ### `create_rfp` - The name "create_rfp" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create a draft freight RFP in the user's FreightFA account with up to 50 lanes, and benchmark each lane against the market. Returns the RFP id, a link to finish and send it in the RFP Builder, and each lane's benchmark. Free accounts can have one RFP. ``` ### `draft_pushback_email` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Draft an email to a broker or carrier pushing back on a truckload quote, using the market benchmark for the lane and this week's market direction. Set want_counter to true to also draft a counter-offer. If no benchmark is given, the national all-in rate for the equipment is used. Included with FreightFA Pro and Desk accounts. ``` ### `estimate_barge_rate` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Estimate an inland waterway barge freight rate for a bulk commodity, origin, destination, distance, and weight, from USDA's weekly downbound grain barge rates. Only priced when both ends are Mississippi/Illinois/Ohio River ports, the lane runs downriver, and the shipment is at least one barge-load (~1,500 short tons, 3,000,000 lb); otherwise returns available: false with the reason. Priced on river miles. Returns a directional benchmark for planning. Each call counts as one estimate toward the account's monthly FreightFA allowance. ``` ### `estimate_intermodal_rate` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Estimate a door-to-door domestic intermodal (rail + truck) rate between two U.S. places: drayage to the nearest Class I ramp, the rail line-haul, and drayage from the destination ramp, with the ramps used. Says when a lane has no intermodal service. Each call counts as one estimate toward the account's monthly FreightFA allowance. ``` ### `estimate_ltl_rate` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Estimate a less-than-truckload rate using FreightFA's CzarLite-basis tariff calculator. Returns a directional benchmark for planning. Each call counts as one estimate toward the account's monthly FreightFA allowance. ``` ### `estimate_network_cost` - Nothing in its name or description says what it does, so it is counted as a write. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Price a supply chain of up to 10 legs (factory to port to warehouse to store, domestic or international) and total it, with each leg's mode, cost, and transit time. Saved to the user's Network Builder. Full costs are included with FreightFA Desk; other accounts can spend a one-time trial run by setting use_trial_run to true, otherwise legs come back without costs. ``` ### `estimate_rail_rate` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Estimate a Class I carload rail freight rate for a commodity, distance, and weight. Pass origin and destination to check for active freight track near both ends (USDOT rail network): rail_access names the railroads nearby, and a lane with no track within 50 miles of an end returns available: false with the reason instead of a price. Don't quote rail on such a lane. Returns a directional benchmark for planning. Each call counts as one estimate toward the account's monthly FreightFA allowance. ``` ### `estimate_truckload_rate` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Estimate a full-truckload freight rate for a lane using FreightFA's DAT-basis rate engine. Returns a directional benchmark for planning.

FreightFA's daily freight brief in one call, with no inputs: today's U.S. national truckload rates per mile (dry van, reefer, flatbed, all-in including fuel) and diesel, next week's truck rate outlook, truck capacity, how rail carload prices are moving, ocean, air, and barge readings with their outlooks, and FreightFA's newest stories with links. Every figure carries its date and source, and a figure that failed FreightFA's checks is listed as held back, with the reason, instead of being shown. Rebuilt several times a day; cite it as FreightFA with the date. Does not count toward the estimate allowance. ``` ### `recommend_mode` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Rank the freight modes (dry van, reefer, flatbed, intermodal, rail, barge, dump truck) for a shipment between two U.S. places, with the reasons for each, and return the lane distance in miles. Use it first when you only have city names or ZIPs, then pass the distance to an estimate_* tool for a price. International lanes return the ocean/air routing instead. Does not count toward the estimate allowance. ``` ## Only reads (14) Looks things up and changes nothing. Claude Code: allow. ### `check_freight_bill` - The description's first verb is "compare": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Compare what a shipper was billed (or quoted) for one truckload or LTL load with today's market price for the same lane. Use it when the user uploads, pastes, or describes a freight bill, carrier or broker invoice, or rate confirmation and asks whether the price is fair. Read the fields off the document yourself and pass only those; never send the document, its text, company or people's names, street addresses, or invoice, PRO, BOL, or account numbers. If the document doesn't say what kind of truck moved the load, ask the user. Dry Van and LTL return a verdict (above_market, at_market, good_price, below_floor) against FreightFA's market quote, negotiation target, and walk-away floor, plus what negotiating would have saved. Reefer and Flatbed return FreightFA's estimate and the gap with no verdict (no_call). The comparison is all-in with fuel; put detention, lumper, liftgate and other extras in accessorials so they are left out. Bills older than 90 days are not judged. Takes places, not miles. Each call counts as one estimate toward the account's monthly FreightFA allowance. ``` ### `explain_freight_term` - The name "explain_freight_term" says "explain": a word for reading. Description, as the server wrote it: ```untrusted-server-text Plain-English definition of a freight market index, ratio, or charge from the FreightFA glossary: OTRI, OTVI, load-to-truck ratio, NTI, Cass Freight Index, RCAF, fuel surcharge, freight class, detention and demurrage, DIM weight, bill of lading, deadhead, accessorials, linehaul, and more.

Does not count toward the allowance. ``` ### `find_intermodal_hubs` - The name "find_intermodal_hubs" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text Look up U.S. intermodal rail hubs by city or state: which Class I railroads serve the metro, the named ramps to ask a carrier about, and notes. Leave both out to list every hub. Does not count toward the allowance. ``` ### `get_barge_outlook` - The name "get_barge_outlook" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text USDA weekly downbound grain barge rates for the river corridor between two Mississippi, Illinois, or Ohio River places, with next week's outlook where it has passed a backtest. Says when the places aren't on a priced corridor. Does not count toward the allowance. ``` ### `get_freight_index_outlook` - The name "get_freight_index_outlook" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Latest reading and next-period outlook for a global freight index: drewry_wci (Drewry World Container Index, $/40ft container), baltic_dry_index (dry bulk shipping), tac_air_index (air cargo rates), or iata_jet_fuel (jet fuel price). Omit the index to get all four. A forecast band is shown only where it has passed a backtest and the source readings are consistent; otherwise the answer says what was held back and why. Does not count toward the allowance. ``` ### `get_freight_news` - The name "get_freight_news" says "get": a word for reading.

Does not count toward the estimate allowance. ``` ### `get_market_snapshot` - The name "get_market_snapshot" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Today's U.S. national truckload rates per mile for dry van, reefer, and flatbed (all-in including fuel, with linehaul and fuel split), FreightFA's live-quote index, and EIA diesel, each with its source week and the change over the last 7 days.
