AtlaSent MCP Server tools 20
evaluateCall this BEFORE performing any sensitive action. Returns a Decision: `allow` (verify the returned permit_token at the execution boundary before proceeding), `deny` (you MUST NOT proceed), or `hold` (do not proceed; route for review).verify_permitCall this AFTER `evaluate` returns allow and BEFORE the protected native side effect. It verifies the permit for the presented execution context. Proceed only when `valid` is true; expired, invalid, replayed, mismatched, or error outcomes must block the action.deploy_serviceExample protected tool. Every call is authorized AND its Permit is verified by AtlaSent before the deploy runs. Denied, held, expired, replayed, mismatched, or unverifiable calls are blocked and never touch the target system.atlasent_evaluateEvaluate an action against your published AtlaSent policies. Returns allow/deny/hold/escalate with a permitToken on allow. Use this when ATLASENT_MODE=remote and you need to gate an action against your hosted policy engine. For agent.* actions the result may carry bound_payload_hash and bound_actor_id: pass them to verify_permit as payload_hash and actor_id, since the permit is bound to them.atlasent_list_policiesList all constraint bundles / policies for this organization.atlasent_list_audit_eventsRetrieve recent evaluation events from the audit log.atlasent_explain_authorityExplain why a principal currently has (or lacks) authority for a scope. Answers 'why may principal P exercise scope/action A in organization O right now?' — strictly read-only, does not change /v1-evaluate, /v1-verify-permit, or any deny/hold/allow semantics; it explains the same facts those paths already read. Every matched authority mechanism (direct_grant, delegation, role_capability) is reported as its own path entry; every excluded or ambiguous relationship is reported as its own unresolved finding.atlasent_integrity_auditAudit the organization's authority graph for internal inconsistency and return the report verbatim. Strictly read-only; changes no policy, permit, or decision. THIS IS NOT A PASS/FAIL HEALTH CHECK and the tool synthesizes no verdict of its own. Each finding carries a three-way `classification`: `defect` is a genuine inconsistency; `non_exercisable` is frequently the CORRECT, healthy state (e.g. an expired grant that is supposed to be expired) and must not be read as a failure; `unresolved` means the proposition COULD NOT BE VERIFIED and must never be treated as clean. Read `summary.audited_scope` before drawing any conclusion from an empty findings list — a short decision window is not an absence of findings. If the audit cannot complete, the server refuses rather than returning a partial report, and this tool surfaces that as an error — never an empty report.atlasent_list_permitsList issued permit tokens for audit and monitoring.atlasent_await_approvalWait for a person to approve or reject a held action in the AtlaSent console. Use the approval_request_id from a 'hold' result. This tool cannot approve anything; it only waits. If approved, it returns a permit_token that you MUST verify with verify_permit before running the action. Any other outcome (rejected, expired, timed out) means the action must not run.atlasent_lookup_actionLook up canonical action specifications from the Authorization Intelligence Library. Returns the permanent canon_id, gate flags (requires_human_approval, requires_mfa, requires_verified_actor, requires_state_snapshot), authorization pattern, risk posture, AI risk classification, regulatory mappings, evidence requirements, and the action's knowledge-graph relationships (what it requires and produces, and which frameworks / control objectives it satisfies) for every governed action type in the Canon. Use `slug` for an exact match (e.g. 'production.deploy') or `query` to describe what you want to do in plain language (e.g. 'deploy the api service to prod', 'grant admin access', 'close the books'). `query` is ranked offline against the vendored Canon and returns a `retrieval` block with `confidence` = confident | ambiguous | none — act only on `confident`; the tool never invents an action type, and a `none` result means the Canon has no such action (see the hint). Omit both to list the full Canon.atlasent_atlas_lookupLook up a canonical AtlaSent concept from the Knowledge Atlas — the compiled graph of the system's own vocabulary (Caller, Authority, Policy, Decision, Permit, Verification, Evidence, Audit Chain, Gate, Trust Root, ...). Returns the concept's canonical definition (its source-of-truth doc), its relationships (what it depends on and what depends on it), the surfaces that realize it, and its ADR / API / SDK / implementation anchors — so every AI host reasons from the same canonical knowledge instead of guessing. Use `id` for an exact concept id (e.g. 'permit', 'audit-chain', 'gate') or `query` for a case-insensitive substring search across id, term, and definition. Omit both to list every concept.- +8 more on the listing page
VPNDetection tools 7
lookup_ipClassify a single IPv4 or IPv6 address: whether it belongs to a VPN, a residential, datacenter, mobile or public proxy, a Tor node, a privacy relay or web gateway, a hosting provider or a CDN, with the provider name where we have one. Private and reserved addresses are answered locally and cost nothing. Always read `coverage.note` before concluding anything from a field that is not in the result.lookup_ipsClassify a list of addresses in one call, returning a map keyed by address so duplicates collapse and the order you passed them stops mattering. Pass the whole list rather than splitting it yourself: a long one is batched for you. Prefer this over repeated `lookup_ip` calls when you already have the list, for example when triaging a log file. An address that fails carries its error in place of a result rather than failing the batch. Always read `coverage.note` before concluding anything from a field that is not in the result.my_entitlementWhat this API key is entitled to and how much of it has been used: the plan, the field tier that decides how much of a lookup answer comes back, the requests counted so far, the allowance, and when it resets. Use it to explain why a field is missing from a lookup, or before a large batch. Usage counts against the anniversary of the subscription rather than the calendar month, and can lag a few seconds behind. A null `hard_limit` means we never stop serving - it is NOT a limit of zero.list_databasesThe database catalog as this API key's organization may see it, one entry per database FAMILY, with `standing` saying where their license stands: `licensed` if the family is theirs today, `expired` if the term has ended, `unlicensed` if it is published but has never been bought. Each entry has a `base` id, which is what the license names, and a `versions` array whose `id` is what the other database tools take - pass `versions[].id` (`cdn_ip_v1`), never the `base` (`cdn_ip`). Ask again rather than holding on to this: it is answered per key and is not the same for everyone.database_metadataWhat is inside one database before you fetch it: the columns in each published format with their types, a few sample rows, the row count, the build date and the file sizes. Use this to answer questions about what a database contains without downloading it - the files reach several GB - and to budget a transfer before starting one.database_checksumThe published digests for one database file, for verifying a copy you already hold or deciding whether a build has changed since you last fetched it. It is licensed like the download itself, so a database this key cannot download is refused here too. Looking up a checksum is not a download and does not appear in `list_downloads`.list_downloadsThis organization's own recent download attempts, newest first, REFUSALS INCLUDED - a denial carries the `outcome` and `http_status` that answer "it stopped working", which nothing else here can. Use it to explain a failing fetch, to confirm a transfer ran, or to check whether a request was theirs. This is a bounded WINDOW of at most 200 rows, so a database missing from the answer means it is not in this window - never that it was never downloaded.
