Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

BuyerAware gives mechanic-grade verdicts on used-car listings. Free tools: tank_alternatives, tank_lookup. analyze_listing costs 1 credit and is async (poll get_verdict). If the user has no key, call create_trial_key.

create_trial_key — Create trial API key
Advertised by the server during the last successful anonymous check.

Create a BuyerAware API key so this user can run verdicts (3 free). Call this once when no key is configured, then show the user the key and tell them to save it. Do not call it again for someone who already has a key — one trial per email address.

analyze_listing — Analyze used-car listing
Advertised by the server during the last successful anonymous check.
Open-world

Start a BuyerAware pre-purchase verdict on ONE used vehicle. Runs a mechanic-grade read: ranked failure points with $ exposure, recalls, seller-claim fact-check, fair price range, adjusted true cost, risk score 1-10, BUY / BUY_WITH_CONDITIONS / WALK_AWAY, a word-for-word negotiation script, and lower-risk 'Tank' alternatives. Supply whichever of listing_url, listing_text or vin you have — at least one is required, and more context sharpens the verdict. Takes ~1-2 minutes: returns a job_id, then poll get_verdict. Costs 1 credit. For 'what should I buy instead' use tank_alternatives, which is free.

tank_alternatives — Find lower-risk alternatives
Advertised by the server during the last successful anonymous check.
Advertised read-only

FREE, no API key needed, answers instantly. Recommend 2-3 lower-risk used vehicles ('Tanks') from BuyerAware's curated 47-platform database that land near a budget. Use when a buyer asks what to buy instead, or what is reliable for $X. Use analyze_listing instead when they have a specific car in mind.

tank_lookup — Look up Tank vehicle
Advertised by the server during the last successful anonymous check.
Advertised read-only

FREE, no API key needed, answers instantly. Look up one platform in BuyerAware's curated database: risk score, verdict, the one known trap, private-party value at a mileage, 5-year operating cost. Covers 47 US-market platforms; anything outside it returns no match, which is itself a signal — follow up with analyze_listing.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http buyeraware-mcp https://api.buyerawareapp.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add buyeraware-mcp --url https://api.buyerawareapp.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable buyeraware-mcp in your MCP settings.
