propose_comment

What it does

A thoughtful public comment on a prospect's post is the best-received first touch on LinkedIn — and the most damaging when it reads like a bot. A person checks every one.

Arguments

This table is generated from the literal inputSchema that tools/list returns, so what your client sees and what this page says are the same object:

{
  "type": "object",
  "properties": {
    "post": {
      "type": "string",
      "description": "Post URL, activity id, or URN (urn:li:activity:…, urn:li:ugcPost:…, urn:li:share:…)"
    },
    "text": {
      "type": "string",
      "description": "The comment, up to 1,250 characters"
    },
    "reply_to": {
      "type": "string",
      "description": "A comment id from list_post_comments, to reply to it"
    },
    "reason": {
      "type": "string",
      "description": "Why, in one or two sentences — shown to the person who approves it"
    },
    "account": {
      "type": "string",
      "description": "Sender account id or name to act as. Defaults to the healthiest connected account."
    },
    "dry_run": {
      "type": "boolean",
      "description": "Check everything (target, do-not-contact, duplicates, text, limits) and return the verdict without proposing anything"
    }
  },
  "required": [
    "post",
    "text"
  ]
}

Request

Paste this, swap the key, and you have called the tool.

curl -s https://topclozer.com/api/mcp \
  -H "Authorization: Bearer tcz_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "propose_comment",
      "arguments": { "post": "urn:li:activity:7332661864792854528", "text": "The part about …", "reason": "On-topic, she is in our ICP" }
    }
  }'

Returns

{ approval_id, status, duplicate, kind, target, warnings, account, next }. With dry_run: { dry_run: true, would_propose: true|false, refusal?, target, checks: { do_not_contact, duplicate, text, limit } } and nothing is queued.

The payload arrives inside an MCP content block — one text block whose body is this JSON, pretty-printed. Parse the string; there is no structured-content field.

{
  "approval_id": "apr_lx3k2a9fq",
  "status": "pending",
  "duplicate": false,
  "kind": "comment",
  "target": { "label": "Post by Dana Whitfield", "id": "urn:li:activity:7332661864792854528" },
  "warnings": [],
  "account": "Marcus Feld",
  "next": "Waiting for a person in the TopClozer console → Approvals. Poll get_approval."
}

Worth knowing

Nothing reaches LinkedIn from this call. A person approves (and may edit) it on the console's Approvals page; it then goes out under the account's Smart Limits, one action per account per pass, inside working hours. The do-not-contact list is checked here and again at send time. LinkedIn caps comments at 1,250 characters.

Rate limit

30 LinkedIn tool calls per 5 minutes, per workspace. Exceeding it returns HTTP 429 with JSON-RPC error -32002 and a Retry-After header. The budget is shared by every LinkedIn tool and counted per workspace, so minting a second key does not buy a second allowance.

The limit exists because an agent retrying in a loop is the request pattern that gets a LinkedIn account restricted, and a restricted account is a much worse outcome for you than a 429. Workspace tools do not spend this budget.
