Overwing

The 41 tools it listed

"Read only" and "Changes data" are the server's own marks. Underlined parameters are required.

1. atlas_agentsRead only

   Search the agent registry (Overwing Atlas)

   Browse or search Overwing Atlas, the registry of AI crawlers, fetchers and browser agents: name, operator, user-agent tokens, Web Bot Auth key directory, robots.txt behaviour, and (with Atlas Pro or Team) purpose class, verification, evasion flags and traffic shares. Filter by free text, purpose (training, search, browser, coding), operator, or verification. Needs an organization key.

   q purpose operator verification limit

2. atlas_list_registrationsRead only

   List your registered agents (Overwing Atlas)

   The agents this organization has registered in Overwing Atlas, newest first, each with its status (pending_verification, pending_review, published, rejected) and, while unverified, the value to publish at the domain. Needs an organization key.

3. atlas_lookupRead only

   Identify a user agent (Overwing Atlas)

   Say what a User-Agent string claims to be and whether the claim can be trusted, from the Overwing Atlas registry of AI crawlers, fetchers and browser agents. Returns the claimed agent, operator, purpose class, verification method (Web Bot Auth signature, user-agent string only, or unattributable) and a trust note. Works with no API key: 10 lookups a day. With a key, metered per day by Atlas tier: free 100, Pro 10,000, Team 100,000. Use it when deciding whether to serve, block, or pay-gate a request, or to understand who is hitting a site.

   user_agent

4. atlas_register_agent

   Register your agent (Overwing Atlas)

   Add an agent or crawler you operate to the Overwing Atlas registry, free, so a site that looks up its User-Agent learns who runs it. Give the agent's name, the operator (the company or person running it), the operator's domain, and the token the User-Agent carries (the product name, such as AcmeBot). The answer carries one value to publish at that domain, as a DNS TXT record or as a file under /.well-known, to prove control of it; then call atlas_verify_registration. A token may not match, contain, or sit inside one already in the registry. This proves control of the domain, not that any given request is yours: the entry is listed as user-agent only unless key_directory_url is a Web Bot Auth key directory on that domain. Only register agents you or your operator actually run. Needs an organization key.

   name operator domain tokens purpose user_agent description policy_url key_directory_url follows_robots_txt

5. atlas_summaryRead only

   Agent traffic and spending summary (Overwing Atlas)

   Public numbers from Overwing Atlas: registry counts by purpose and verification, published browser-agent traffic shares, sector field-scan headlines (e.g. how many OSINT sites carry AI-crawler rules or any agent-payable surface), and the summary of the Agent Consumers report on what agents actually spend. No key needed.

6. atlas_verify_registration

   Verify and publish a registration (Overwing Atlas)

   Look for the proof at the operator's domain: the DNS TXT record or the file that atlas_register_agent asked for. Found: the entry is published in the registry, or held for a person when the operator name already belongs to someone. Not found: an error saying what was looked for; DNS changes can take a few minutes, and calling again is safe. Needs an organization key.

   id

7. atlas_withdraw_registrationChanges data

   Withdraw a registration (Overwing Atlas)

   Withdraw a registration. A published entry leaves the registry, so lookups stop naming the agent; an unfinished request is abandoned. This cannot be undone: register again to put it back. Needs an organization key.

   id

8. beacon_reportRead only

   Read a reachability report (Overwing Beacon)

   The report for a check started with beacon_start. The first call runs the check. With an Overwing key on the connection: score (0 to 100), verdict (yes, partly, no), the find / read / use answers, every check with what was found and a fix when it did not pass, and top_fixes ranked by value. With no key, the summary of the same report: score, verdict, the three answers and the first fix (access=summary). Answers 202 while the check is running (ask again in a few seconds). No key needed for the summary.

   id

9. beacon_sampleRead only

   Sample reachability report (Overwing Beacon)

   A real Overwing Beacon report, free: the check of overwing.ai itself, refreshed daily. Read it to see exactly what a full report holds before starting a check. No key needed.

10. beacon_start

    Start a reachability check (Overwing Beacon)

    Overwing Beacon answers one question about a site: is this product reachable by agents? It checks robots.txt rules for AI agents, llms.txt, the sitemap, the MCP server card, hosted MCP endpoint and MCP Registry listing, the A2A agent card, OpenAPI discovery, and how the home page reads to a model, then returns three answers (find, read, use), a score and the fixes worth making. This tool starts a check and returns its id; it is free. Then call beacon_report with the id, which runs the check (about twenty seconds). With an Overwing key on the connection beacon_report returns the full report and the check is saved to that dashboard; with no key it returns the summary: the score, the three answers and the first fix. A key is free (POST /api/v1/signup). An agent with a wallet and no account can instead pay $1 in USDC over x402 and get the full report in one call: GET /api/x402/beacon?url=<site>. Call beacon_sample to see a real report in full. No key needed.

    url

11. create_account

    Create your own account (no email)

    Create an Overwing account for yourself, with no email: an organization and an API key, returned once. Nothing is sent to anyone. Use it when you have no key and nobody has given you one; do not create a second account if you already have a key (whoami says which account a key belongs to). The key is the account, so store it at once: with no email there is no reset link. It starts at 50 evaluations a day with Beacon summaries; proving a domain (prove_domain, verify_domain) raises that to the normal free limits and full Beacon reports, and makes a lost key recoverable. This server does not keep the key: send it as Authorization: Bearer on the MCP connection for the tools that need one. Tell the person you work for that you made the account and where the key is kept. No key needed.

    org_name use_for_session

12. create_rule_set

    Create rule set

    Create a custom rule set with 1 to 25 rules. Each rule is a choice (pick one option), score (position on an ordered scale), or noul (yes/no) question with a fail condition, optional review threshold, weight, and action (block, redact, or review) that callers should take when it fails. Rule instructions may reference `context.*` fields that callers pass with each evaluation. Needs an organization key.

    name slug description rules

13. evaluate

    Evaluate text

    Works with no API key: 10 evaluations a day, inputs up to 2,000 characters, and the text is not stored. With a key: 250 a day and up, inputs up to 100,000 characters, and your own rule sets. Score any text (typically an LLM's output) against an Overwing rule set. The text can be in any language; tested in Spanish, Portuguese, French, German, Japanese, Chinese, Korean, Arabic and Hindi. Results come back in English. Returns an aggregate verdict of pass, fail, or review, a recommended_action (block, redact, review, or allow), and per-rule answers with probability, confidence, and the rule's action. Act on recommended_action: block means do not send, redact means remove the flagged content and resend, review means ask a human or a slower model, allow means proceed. Prebuilt sets: 'content-safety' (toxicity, PII, self-harm, sexual content, severity) and 'outbound-message', which also takes a context object (recipient, channel, owns_contact_info) so PII that the recipient already owns is no

    input rule_set metadata context store

14. evaluate_batch

    Evaluate many texts

    Score up to 50 texts against one rule set in a single call. Each item counts as one evaluation. Returns a summary plus per-item verdicts; items can fail independently. Needs an organization key.

    items rule_set context store

15. feedback

    Tell Overwing what went wrong

    Send one message to the people who run Overwing: a verdict you think was wrong, an error you could not act on, a payment you could not make, a tool that did not do what its description says. Read by a person, not answered automatically; give a contact if you want an answer. No key needed.

    message about evaluation_id contact

16. get_evaluationRead only

    Get evaluation

    Fetch a stored evaluation by id, including the original input and per-rule results. Needs an organization key.

    id

17. get_rule_setRead only

    Get rule set

    Fetch a rule set with its full rule definitions. Use 'content-safety' as a worked example when writing your own. Needs an organization key.

    slug

18. get_usageRead only

    Get usage

    Daily usage, remaining quota for today, and plan limits. Needs an organization key.

    days

19. list_evaluationsRead only

    List evaluations

    List recent evaluations, newest first, with optional verdict and rule set filters. Use next_cursor to page. Needs an organization key.

    limit verdict rule_set cursor

20. list_plansRead only

    List plans

    Public plan catalog: prices, daily limits, and per-minute burst limits. No API key needed.

21. list_rule_setsRead only

    List rule sets

    List the prebuilt and custom rule sets available to this organization. Needs an organization key.

    include_inactive

22. preflight_check

    Check a Solana transaction before signing it (Overwing Preflight)

    Call this before signing any Solana transaction. Overwing Preflight simulates the unsigned transaction against the chain as it is now, works out what it would take from the wallet you name (SOL, tokens, and control of its token accounts) and answers allow or refuse against your policy, with every reason. Sign only if decision is "allow". Treat a refusal, an error, or anything else as do not sign. A verdict describes one moment and covers a transaction that lands within about two minutes, so sign and send at once or check again. This tool takes the serialized transaction and a policy; it never needs a private key and must never be given one. One check counts as one evaluation. Needs an organization key.

    transaction policy

23. preflight_overviewRead only

    What Preflight checks and how to call it (Overwing Preflight)

    The reference for Overwing Preflight: every policy field, every reason code a refusal can carry, what a verdict does and does not promise, the price, and the terms of the guarantee. Read it once before the first preflight_check. No key needed.

24. preflight_paymentRead only

    Should I sign this x402 payment? (Overwing Preflight)

    Call this with the 402 you were given, before signing an x402 payment. It reads the terms (network, asset, amount, payee, timeout, resource) and answers allow, review or refuse with reasons: the terms against your policy, the payee against x402-list's directory (verified delivery, recorded settlements, buyers, shared payout addresses) and the server's own /.well-known/x402 manifest, and the price against what is recorded for that endpoint. Not a simulation and not a guarantee. Sign only on allow; on review, ask the person you work for. No key needed for a few checks a day.

    payment_required requested_url network policy

25. preflight_recordRead only

    The public record (Overwing Preflight)

    Everything Preflight has said and how it held up: counts of verdicts and misses, every miss with what the chain showed, the latest verdicts, and what the guarantee's reserve holds. Read it before deciding whether to rely on Preflight. No key needed.

26. preflight_report

    Report the transaction that landed (Overwing Preflight)

    After a transaction that Preflight allowed has landed, report its signature. Preflight reads the landed transaction from the chain and says whether the allow held: not_a_miss, or miss when it took more from the wallet than the policy permitted. The outcome is published. A covered miss is paid to the wallet in the verdict, never to whoever reported it. No key needed.

    id signature

27. preflight_verdictRead only

    Read a published verdict (Overwing Preflight)

    The public record of one Preflight verdict: its decision, reason codes, the programs the transaction would run, the transaction's digest, our signature, and every landed transaction reported against it. Never the wallet, the amounts or the transaction. No key needed.

    id

28. prove_domain

    Prove a domain for your account

    Begin proving that your account controls a domain. For an account with no email the domain stands in for one: it raises the limits to the normal free tier, opens full Beacon reports, and lets a lost key be replaced. Returns one value to publish at the domain, as a DNS TXT record or as a file under /.well-known; then call verify_domain. One domain belongs to one account. Calling again for the same domain returns the same value. Needs an organization key.

    domain

29. tower_capabilitiesRead only

    What may I do? (Overwing Tower)

    List the operations this agent is allowed to call, each with the JSON Schema its input must match and its compensating operation. Call this first; build inputs from the schema rather than guessing. Needs an agent key.

30. tower_compensate

    Undo an executed action (Overwing Tower)

    Run the compensating operation for an executed action, for example cancel the order that create_order made. Runs once; repeating it returns the first outcome. Needs an agent key.

    action_id

31. tower_create_agent

    Create an agent identity (Overwing Tower)

    Create a scoped agent identity and its key. Needs an organization key. Scope it to the operations the agent needs (for example create_order) rather than * where you can. The key (ow_agent_...) is returned once, in this result, and this server does not keep it: store it, and send it as the Authorization bearer on a connection used for the agent tools (tower_capabilities, tower_decide, tower_submit_action, tower_get_action, tower_compensate, tower_get_receipt, tower_verify_receipts). Revoke with tower_revoke_agent.

    name scopes use_for_session

32. tower_decideRead only

    Would this be allowed? (Overwing Tower)

    Ask Tower how it would rule on an operation without doing anything: auto (would execute), review (a person must approve), or reject. Returns the score, the reason, and each policy question's answer. No side effects. Needs an agent key.

    operation input

33. tower_get_actionRead only

    Get an action (Overwing Tower)

    Status and result of an action: pending, approved, executed, failed, compensated, or rejected. Use it to poll an action that is waiting on human review. Needs an agent key.

    action_id

34. tower_get_receiptRead only

    Get a receipt (Overwing Tower)

    Fetch one signed receipt by id or by sequence number: the payload, its hash, the previous link's hash, and the Ed25519 signature. Needs an agent key.

    id

35. tower_list_agentsRead only

    List agents (Overwing Tower)

    List this organization's Tower agents with scopes, status and last use. Keys are never returned. Needs an organization key.

36. tower_load_template

    Load the starter workflow (Overwing Tower)

    Set up Overwing Tower for this organization by loading the starter workflow: email purchase order to order entry, with create_order, update_order and cancel_order against a mock IBM i system, and a starter policy. Idempotent. Needs an organization key. Returns a sample input you can submit. Next: tower_create_agent.

37. tower_revoke_agentChanges data

    Revoke an agent (Overwing Tower)

    Revoke an agent. Its key stops working at once and cannot be restored. Needs an organization key.

    agent_id

38. tower_submit_action

    Request an action (Overwing Tower)

    Ask Tower to perform an operation on the legacy system. Tower decides: executed (done), pending (a person must approve; poll tower_get_action, do not resubmit), or rejected (do not retry unchanged). Always send an idempotency_key that is stable for this business request, such as the source message id: repeating a key returns the original outcome instead of acting twice. Set dry_run to see the decision without executing. Needs an agent key.

    operation input idempotency_key dry_run

39. tower_verify_receiptsRead only

    Verify the receipt chain (Overwing Tower)

    Recompute every hash and check every signature over a range of this organization's receipts. Reports the first break, if any. Defaults to the whole chain (up to 5,000 links per call). Needs an agent key.

    from to

40. verify_domain

    Verify the domain proof

    Look for the value prove_domain asked for, at the domain. Found: the domain is the account's. Not found: an error saying what was looked for; DNS changes can take a few minutes, and calling again is safe. Needs an organization key.

41. whoamiRead only

    Who am I

    Identify the organization and plan behind the API key on this request, the key's scope, the organization's data settings (store_inputs, retention_days), and whether billing is set up. Needs an organization key.
