    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Raw names from tools/list. Only developers need these.

    verify_sourceConfirm a URL is reachable and actually says what it is claimed to say, BEFORE you spend a long context reading or acting on it. Catches dead links, pages that changed, and pages that do not support the claim attached to them. One cheap call here replaces a full fetch-and-reason pass that ends in nothing. Costs $0.20 in USDC.
    check_provenanceDetect whether a piece of text was model-generated and whether this system has emitted something materially identical before. Call before writing to long-term memory: model output that gets re-ingested comes back later as a trusted fact, and every downstream run that reasons over it is wasted work you will not be able to trace. Costs $0.25 in USDC.
    verify_claimIndependently verify a claim against a real check — an HTTP fetch, a file, or a command — instead of taking an assertion on trust. Call it on the premise BEFORE committing to a multi-step plan that depends on it, and to confirm work another agent reports as done. A false premise caught here costs $0.35; caught at the end of the plan it costs the whole plan. Costs $0.35 in USDC.
    answer_shareAsk a live AI assistant a buyer question and report whether a given brand is named, at what position, and which competitors appear instead. Use for competitive and market research that reflects what assistants say right now. Costs $0.75 in USDC.
    verify_answerCheck an entire AI answer: open every source it cited, say which are real, which are missing or invented, and which are merely paywalled. Returns a PUBLIC receipt URL you can cite as proof. Call before storing or repeating another model's answer — an invented source that enters your state is re-reasoned over on every later run. Costs $1.00 in USDC.
    report_wasteRecord work your agent run spent money on and then threw away, and get back your waste rate — wasted spend as a share of total spend. Agent waste never raises an exception, so it is invisible to normal monitoring; this is the ledger for it. Report a discarded plan, a wrong target, a retry, or a call that returned nothing usable. Free.
    waste_reportRead the agent-integrity ledger: total spend, spend that produced nothing usable, the waste rate, and a breakdown by failure kind and by agent. Self-reported and independently detected waste are reported separately — an agent grading its own work is not evidence. Free.
