api record

opchain is a concept→spec→design→build→ship pipeline of skills. On any /oc-* command, or any request to build, spec, design, audit, deploy, or ship software, FIRST call route (or get_skill) to pick the skill, read get_orchestrator once per session, then load the skill's SKILL.md with get_skill and follow it verbatim. If you do not already retain a private checkpoint sessionId, call create_checkpoint_session once, then use its returned token with read_checkpoint/write_checkpoint to resume and persist progress across sessions. Never invent or share it. Note: /oc-* commands are also exposed as…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 7 tools
2 open 5 never probed 2 of 7 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_skills open 2h ago

    List every opchain skill (id, displayName, description, phases, commands). Call this first to see the concept→ship pipeline.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • get_orchestrator open 2h ago

    Return the shared orchestrator protocol (welcome flow, pipeline map, active-chaining rules). Read once at the start of a session.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • route unknown never probed

    Map a request or an /oc-* command to the skill that should handle it, with the entry phase. Use when you're unsure which skill fits.

    mcp-tool

    {
  "type": "object",
  "required": [
    "query"
  ],
  "properties": {
    "query": {
      "type": "string",
      "description": "An /oc-* command (e.g. /oc-discover) or a natural-language request (e.g. 'build me an app')."
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • get_skill unknown never probed

    Return the full SKILL.md (the instructions) for one skill id. Load it, then follow it. Read get_orchestrator once before your first get_skill in a session.

    mcp-tool

    {
  "type": "object",
  "required": [
    "id"
  ],
  "properties": {
    "id": {
      "type": "string",
      "description": "Skill id, e.g. oc-app-architect."
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • create_checkpoint_session unknown never probed

    Create a private server-issued session for checkpoint storage. Retain the returned sessionId and use it with read_checkpoint/write_checkpoint; never invent or share one.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • read_checkpoint unknown never probed

    Read a skill's saved session checkpoint (where you left off). sessionId must be a private token returned by create_checkpoint_session.

    mcp-tool

    {
  "type": "object",
  "required": [
    "skill",
    "sessionId"
  ],
  "properties": {
    "skill": {
      "type": "string"
    },
    "sessionId": {
      "type": "string",
      "maxLength": 128,
      "minLength": 36,
      "description": "Private token returned by create_checkpoint_session."
    }
  },
  "additionalProperties": false
}
    arguments 19 lines
  • write_checkpoint unknown never probed

    Persist a skill's session checkpoint so progress survives across sessions. Stores the object as given (any JSON object up to 64 KiB); it does not validate it against the opchain checkpoint protocol, so write the shape the protocol documents.

    mcp-tool

    {
  "type": "object",
  "required": [
    "skill",
    "sessionId",
    "checkpoint"
  ],
  "properties": {
    "skill": {
      "type": "string"
    },
    "sessionId": {
      "type": "string",
      "maxLength": 128,
      "minLength": 36,
      "description": "Private token returned by create_checkpoint_session."
    },
    "checkpoint": {
      "type": "object",
      "description": "The checkpoint JSON to store (skill_state, next_actions, etc.)."
    },
    "expectedRevision": {
      "oneOf": [
        {
          "type": "string",
          "minLength": 1
        },
        {
          "type": "null"
        }
      ],
      "description": "Local durable transport only: null creates only if absent; a revision updates only that revision. Omit for atomic unguarded replacement."
    }
  },
  "additionalProperties": false
}
    arguments 36 lines
_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
