⚠️ Block users
messenger_post_blacklist_v2Destructive
Block users from messaging by adding them to the blacklist with optional reason and context. Prevents unwanted communication from spam, fraud, or abusive accounts.
Instructions
Adds one or more users to the account's BLACKLIST. WARNING: a blocked user will no longer be able to message you in the messenger; this immediately affects a third party and requires confirmation. Accepts an array of users with a user_id and an optional context (item_id and reason). reason_id: 1=spam, 2=fraud, 3=insults and rudeness, 4=other reason.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| users | Yes | List of users to block (at least one), each as { user_id, context? }. | |
| dryRun | No | v0.7.0: if true — returns a preview of the HTTP request without calling the Avito API. Safe for inspecting exactly what would be done. Default: the value of AVITO_MCP_DRY_RUN_DEFAULT (usually false). | |
| user_id | No | Avito account ID that maintains the blacklist. Defaults to Profile_id from .env. | |
| idempotencyKey | No | v0.7.0: optional key for duplicate protection. A repeat call with the same key within AVITO_MCP_IDEMPOTENCY_TTL_SEC returns the cached result. The same key with different args returns a conflict error. Keys are stored as bounded SHA-256 fingerprints. |
