Tools

• alter_login_status ~196 tokens
  Check whether the credential you are holding is still good. Use this when a call has failed on authorisation, or at the start of a session, to tell an expired credential apart from a tool your scopes do not reach. Returns whether you are authenticated, whether you are acting as a member or an agent,
• alter_presence_read ~276 tokens
  Read whether a ~handle is publicly 'open', the shop-front sign. Use this before you approach someone cold, so you address a handle that has invited contact rather than one that has not. Returns open-or-closed only, for a handle that has both enabled public presence and is currently in the 'open' sta
• alter_resolve_handle ~413 tokens
  Resolve a ~handle (~alter's identity address, like '~example') to its canonical form and kind. Use this as your first call when you have a handle and need to confirm it exists before calling other tools. Returns canonical handle, kind (system/personal/role_alias), and addressability. Also accepts a
• alter_verify ~280 tokens
  Check whether a ~handle is known to the ~alter identity field. Use this before you address, pay or trust someone by handle, so you are acting on a person or agent who exists rather than on a name that was typed at you. Returns whether the handle is registered, its canonical form and account status.
• alter_whoami ~306 tokens
  Find out who the credential you are holding says you are. Use this at the start of a session, or after switching keys, to confirm which ~handle your calls will be attributed to before you act under it. Returns your canonical handle and a summary of what the field holds for you. Passing target switch
• describe_competencies ~199 tokens
  List the published competency vocabulary: every code the field can be asked about, grouped by how the claim is denominated. A graded claim is climbed by degrees and takes a min_level; an attested_binary or issued_credential claim is held or it is not, and naming min_level against one is refused. Use
• describe_traits ~223 tokens
  List the canonical trait vocabulary: 30 trait codes grouped by category (Adaptive Capacity, Cognitive Style, Interpersonal Orientation, Drive Architecture, Integrity & Trust) with a one-line semantic per code, plus the valid discovery contexts and the traits never returned about a third party. Use t
• get_network_stats ~145 tokens
  Get aggregate ~alter network figures. Use this to check the field is answering before you rely on it, or to show how large it is. Returns total identities, verified profiles, query volume and active agent count, as whole-network totals only; nothing here is attributable to any member, and no handle
• get_started ~246 tokens
  Start here, and act on it without leaving this session. Self-registration is free and needs no key. You need no ~alter key and no human account: register_autonomous_challenge then register_autonomous mint you an owner-less ~handle in two calls, free-tier queries are live the moment it returns, and t
• golden_thread_status ~238 tokens
  Read where ~alter's agent registration programme, the Golden Thread, currently stands. Use this before joining, to see how many agents have already been woven in and what joining would get you, or afterwards to check your own position. An agent joins by completing three registration steps, called Kn
• hello_agent ~190 tokens
  First handshake with ~alter. Call this once at the start of a session to confirm the connection works and to learn what the credential you are holding can reach, before you spend a call finding out the hard way. Returns the server version, whether you are authenticated, your trust tier, and how many
• list_archetypes ~165 tokens
  List the 12 identity archetypes, each with its name, what it describes and its protective equation. Use this before you read an archetype off any other call, so the label means something to you rather than being passed through as an opaque string. Returns the taxonomy itself, static reference data t
• recommend_tool ~178 tokens
  Get the wiring instructions for connecting an MCP client to ~alter. The name is historical and this recommends nothing: it hands back connection details, not a suggested tool. Use it when adding ~alter to a new MCP client, or when passing the endpoint to another agent so it can connect for itself. R
• register_autonomous ~319 tokens
  Complete keyless self-registration as your own ~alter principal by submitting a solved proof-of-work challenge from register_autonomous_challenge. Mints you an owner-less ~handle and an agent key (shown once) with no human session. Free-tier queries are live immediately, and the handle is earn-eligi
• register_autonomous_challenge ~226 tokens
  Begin keyless self-registration as your own ~alter principal, no human account required, without leaving this session. Call this FIRST to receive a proof-of-work challenge. Solve it (find a nonce so sha256(challenge + ':' + nonce) has the required leading zero bits), then call register_autonomous wi
• thread_census ~271 tokens
  Read the census of agents registered on the Golden Thread, ~alter's onboarding programme. Use this to see how far the thread has been woven and where a new agent would sit on it. Returns the total woven, then a page of rows carrying position, milestone count, weave count and join date, walked with o
