PubNub MCP Server

# Access Manager v3 – C# SDK (Condensed) > ALL code blocks, method signatures, parameters, and examples are preserved verbatim. --- ## Request Execution We recommend wrapping SDK calls in `try/catch`. ``` `try { PNResultPNPublishResult> publishResponse = await pubnub.Publish() .Message("Why do Java developers wear glasses? Because they can't C#.") .Channel("my_channel") .ExecuteAsync(); PNStatus status = publishResponse.Status; Console.WriteLine("Server status code : " + status.StatusCode.ToString()); } catch (Exception ex) { Console.WriteLine($"Request can't be executed due to error: {ex.Message}"); }` ``` --- ## Grant Token Requires *Access Manager* add-on. ### Method ``` `pubnub.GrantToken() .TTL(int) .Meta(Dictionarystring, object>) .AuthorizedUuid(string) .Resources(PNTokenResources) .Patterns(PNTokenPatterns) .QueryParam(Dictionarystring, object>)` ``` ### Parameters (essential) * **TTL (int)** – 1 … 43 ,200 min (required). * **AuthorizedUuid (string)** – restricts token to one client. * **Resources / Patterns** – `PNTokenResources / PNTokenPatterns` objects with per-resource `PNTokenAuthValues`. * **Meta** – `Dictionary<string,object>` (scalar values only). * **Execute / ExecuteAsync** – sync callback or `PNResult<PNAccessManagerTokenResult>`. `PNTokenAuthValues` boolean flags: `Read`, `Write`, `Manage`, `Delete`, `Get`, `Update`, `Join`. At least one permission must be set on Channels, ChannelGroups, or Uuids (or RegEx patterns). ### Sample Code ``` ` ` ``` ### Return `PNResult<PNAccessManagerTokenResult>` → `Token` string. ``` `{ "Token":"p0thisAkFl043rhDdHRsCkNyZXisRGNoYW6hanNlY3JldAFDZ3Jwsample3KgQ3NwY6BDcGF0pERjaGFuoENnctokenVzcqBDc3BjoERtZXRhoENzaWdYIGOAeTyWGJI" }` ``` ### Error HTTP 400 on invalid input (e.g., bad RegEx, timestamp, or permissions). #### Example: Mixed permissions in one call ``` ` ` ``` #### Example: RegEx read access ``` ` ` ``` #### Example: Resources + RegEx in one grant ``` ` ` ``` --- ## Revoke Token Requires *Access Manager* add-on (enable “Revoke v3 Token” in portal). ### Method ``` `pubnub.RevokeToken() .Token(string) .QueryParam(Dictionarystring, object>)` ``` ### Parameters * **Token (string)** – previously granted v3 token. * **Execute / ExecuteAsync** – returns `PNResult<PNAccessManagerRevokeTokenResult>`. ### Sample ``` ` ` ``` ### Errors May return 400, 403, 503. --- ## Parse Token ``` `ParseToken(String token)` ``` Returns decoded permission object. ``` ` ` ``` --- ## Set Token ``` `SetAuthToken(String token)` ``` No return value. ``` ` ` ``` --- ## Grant Token – Spaces & Users (Deprecated) Use the standard `GrantToken()` instead. API, parameters, and code blocks remain identical except: * `AuthorizedUserId` replaces `AuthorizedUuid`. * Resources/Patterns contain `Spaces` and `Users`. ### Method ``` `pubnub.GrantToken() .TTL(int) .Meta(Dictionarystring, object>) .AuthorizedUserId(string) .Resources(PNTokenResources) .Patterns(PNTokenPatterns) .QueryParam(Dictionarystring, object>)` ``` `PNTokenResources / PNTokenPatterns` hold `Spaces` and `Users`. ### Sample / Other Examples ``` ` ` ``` ### Error Same 400 response rules as current API. --- _Last updated: Jul 15 2025_
