One request.
A usable answer.
TaskRail is a remote MCP server for agents that need a verified delivered price or the official path through a real-world task. The result includes its sources, limitations, and receipt.

Launch surface
Four narrow jobs, done with evidence.
TaskRail starts with work that can be checked. Each response separates what the sources confirm from what still needs verification.
02 / completion-pathLaunch tool
Fastest official task path
Returns ordered steps and official destinations for tasks such as cancellation, returns, or account support. It does not log in or submit forms.
03 / deals-usedLaunch tool
Used and refurbished value
Finds exact-match refurbished, open-box, and used offers from approved public sources, then compares condition, returns, warranty, and savings against the verified new price.
04 / compatibilityLaunch tool
Product compatibility
Retrieves official specifications, applies deterministic fitment rules, and uses NHTSA vehicle identity when a VIN is supplied. Missing critical facts produce an unknown result—not a guess.
Request lifecycle
The buyer stays in control of payment.
Discover for free
Inspect capabilities or request a quote. No retrieval and no payment happen at this step.
Sign the x402 request
A compatible wallet or platform reviews and signs the exact amount, asset, network, and recipient.
Receive evidence
The response includes sources, freshness, limitations, and a public receipt reference when settlement completes.
For developers
Small surface. Clear contract.
Use Streamable HTTP through MCP or call the public REST endpoints directly. Discovery and quoting are free.
