api record

Mutator automates short-form marketing: it generates posts into a library, and publishes the ones a person chooses, on a schedule.

Three rules govern everything here.

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.

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.

  • mutator_get_analytics auth-required 9h ago

    Read how published content performed over a window of days — the same report the dashboard shows. Use it to answer what worked and to suggest what to run next.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "days": {
      "type": "integer",
      "maximum": 365,
      "minimum": 1,
      "description": "Window in days. Defaults to 30."
    }
  },
  "additionalProperties": false
}
    arguments 12 lines
  • mutator_get_spend_limits auth-required 9h ago

    Report the workspace's daily and monthly spending ceilings and how much of each is already committed. Generation runs on Mutator's own accounts and is paid for in credits, and the ceilings still apply, so check this before starting anything that generates — a run that would pass a ceiling is refused before any provider is contacted.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • mutator_list_approvals auth-required 9h ago

    Always empty. Approvals were removed on 20 September 2026: a run publishes nothing, and a post is made by a person picking a file, an account and a time in Mutator. Tell the person that, rather than reporting an empty queue as if something were wrong. Use mutator_get_run to report what a run made.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • mutator_list_connections auth-required never probed

    List the accounts and providers this workspace has connected, with the id a publishing step needs. A publish step points at a connection, not at a platform name — there is no 'post to TikTok' field, only 'post to this account, which happens to be TikTok'. Read this before wiring one, because a publish step with no connection is refused at activation rather than saved and forgotten.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • mutator_whoami auth-required never probed

    Confirm the API key works and report which Mutator workspace it reaches and what it may do. Call this first when the connection is new or a later call fails with an authorization error.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • mutator_list_automations auth-required never probed

    List every automation in the workspace with its id, name and status (draft, active or paused). Start here when the user refers to an automation by name and you need its id.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • mutator_start_run auth-required never probed

    Start a run of an automation. Defaults to a DRY RUN, which skips publishing but not generation: it makes the same paid generation calls a real run makes, costs the same credits or provider charges, and counts against the same spend limits. So start one only when the user wants a run, and leave it dry unless they have asked for a real run in this conversation. A real run still publishes nothing on its own: anything it generates goes to the workspace's library, and is posted only when a person schedules it in Mutator. Requires an idempotencyKey; replaying the same value returns the original run instead of starting a second one, so retry with the same key rather than a new one.

    mcp-tool

    {
  "type": "object",
  "required": [
    "automationId",
    "idempotencyKey"
  ],
  "properties": {
    "dryRun": {
      "type": "boolean",
      "description": "Defaults to true. Pass false only when the user has explicitly asked for a real run."
    },
    "automationId": {
      "type": "string",
      "description": "Automation id from mutator_list_automations."
    },
    "idempotencyKey": {
      "type": "string",
      "maxLength": 80,
      "minLength": 8,
      "description": "Your own key for this attempt, 8-80 characters. Reuse it verbatim when retrying."
    }
  },
  "additionalProperties": false
}
    arguments 24 lines
  • mutator_get_automation auth-required never probed

    Read one automation in detail: status, its schedule if it has one, and its own spending limits. Use it before starting a run to check the automation is active and what a run may cost.

    mcp-tool

    {
  "type": "object",
  "required": [
    "automationId"
  ],
  "properties": {
    "automationId": {
      "type": "string",
      "description": "Automation id from mutator_list_automations."
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • mutator_list_runs auth-required never probed

    List recent runs of one automation, newest first, with status, whether each was a dry run, and what it cost. Use it to answer 'did it work' and 'what did it cost'.

    mcp-tool

    {
  "type": "object",
  "required": [
    "automationId"
  ],
  "properties": {
    "limit": {
      "type": "integer",
      "maximum": 50,
      "minimum": 1,
      "description": "How many runs to return. Defaults to 10."
    },
    "automationId": {
      "type": "string",
      "description": "Automation id from mutator_list_automations."
    }
  },
  "additionalProperties": false
}
    arguments 19 lines
  • mutator_get_run auth-required never probed

    Read one run with its per-step detail, so a failure can be traced to the step that caused it. Runs are asynchronous: a run still marked running has not finished, so poll rather than assume.

    mcp-tool

    {
  "type": "object",
  "required": [
    "runId"
  ],
  "properties": {
    "runId": {
      "type": "string",
      "description": "Run id, as returned by mutator_start_run."
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • mutator_list_brands auth-required never probed

    List the brands in the workspace. Every automation belongs to one, so this is the first call when creating anything: mutator_create_automation needs a brandId from here. The brand carries the voice an automation writes in — audience, tone, call to action.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • mutator_list_formats auth-required never probed

    The content formats this product actually knows, and the niches they suit. Use one of these when building — do not invent a format. There is no trend, virality or discovery data anywhere in Mutator: nothing here knows what is performing on any platform this week, and a niche only ORDERS this list, it never filters it. If a user asks for 'viral formats in my niche', these are the formats, ordered by fit, and the word viral is not something this tool can stand behind.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "niche": {
      "type": "string",
      "description": "Optional niche id to order the list by fit. Formats that suit no niche still appear."
    }
  },
  "additionalProperties": false
}
    arguments 10 lines
  • mutator_list_step_types auth-required never probed

    The complete vocabulary of steps, with the settings each one takes. An automation is a graph of these joined by edges. Read this before building one: the step list is closed, and a graph naming a type that is not here is refused. Most settings have defaults, so a step can usually be sent with an empty config and still run.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • mutator_create_automation auth-required never probed

    Create a new automation as a DRAFT, optionally with its steps already wired. It is never activated and never runs: a draft has no active version, the scheduler only fires active automations, and nothing here can activate one. The person opens it, reads it, and turns it on. An invalid graph is still saved — the problems come back as `issues` for you to fix and save again, rather than the whole call failing. Report what you built and what is left to decide; do not describe it as live.

    mcp-tool

    {
  "type": "object",
  "required": [
    "brandId",
    "name"
  ],
  "properties": {
    "name": {

      "maxLength": 120,
      "minLength": 1
    },

}
    arguments 46 lines
  • mutator_save_automation_graph auth-required never probed

    Replace an automation's steps with the ones given, saved as a DRAFT. An active automation keeps running its current version until a person activates the draft, so editing something live is safe. Problems come back as `issues` rather than failing the call — read them and save a corrected graph.

    mcp-tool

    {
  "type": "object",
  "required": [
    "automationId",
    "graph"
  ],
  "properties": {
    "graph": {

      "required": [
        "nodes",

          }
        },

    arguments 36 lines
  • mutator_set_schedule auth-required never probed

    Set when an automation would run, saved switched OFF. Turning a schedule on requires an already-active automation, so this can only ever prepare one — the settings survive until a person activates it. A schedule runs an automation AT MOST ONCE A DAY: it holds a single time, and frequency chooses which days rather than how many times within one. Two posts a day is not a schedule setting: it is one daily run producing two items, with maxPostsPerDay on the publishing step.

_ 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.
