Quality: 55/100 (Good) | Auth: No auth required
Tencent Lexiang MCP Server
Developer Tools · Local stdio
Quality: 49/100 (Fair) | Auth: No auth required
Verdict Summary: Choose SingChat if you need specialized Developer Tools tools running via a hosted cloud SSE transport. Choose Tencent Lexiang MCP Server if your workspace requires Developer Tools integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
S
Choose SingChat when:
You need dedicated capabilities in the Developer Tools domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Health check for the SingChat MCP server. Returns 'pong' and whether this request is authenticated to a workspace.
singchat_setup
Get the user up and running with SingChat live-chat. Call this FIRST. If no authenticated workspace is configured, this creates a brand-new free workspace and returns a short-lived, single-use browser claim link plus the website embed snippet. The user chooses their own sign-in details in the browser; no reusable credentials are returned to the model. If a workspace is already authenticated, it returns THIS workspace's embed snippet and dashboard link (it never creates a duplicate workspace).
get_embed_snippet
Return the SingChat chat-widget embed code for this workspace's web inbox, in three flavors: plain HTML, React (useEffect), and Next.js (next/script). Requires a workspace API key. Optionally pass `platform` to get just one flavor.
claim_account
Return the link to claim (permanently secure) this SingChat workspace by setting an email and password. Use this for workspaces that were auto-created via MCP so the user does not lose access. The link is single-use and expires after 15 minutes. Requires an authenticated legacy workspace.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
SingChat is categorized under Developer Tools and uses a remote streaming HTTP/SSE transport. In contrast, Tencent Lexiang MCP Server belongs to Developer Tools using local stdio subprocess. Select SingChat when you need capabilities focused on developer tools and Tencent Lexiang MCP Server when you require tools for developer tools.
List the workspace's support conversations (agent/inbox view), newest activity first. Optionally filter by status or a free-text search over the contact name/email and last message. Returns a compact list: id, contact name, status, unreadCount, last message preview, updatedAt.
get_conversation
Fetch a single conversation with its contact details and the most recent messages (oldest→newest).
reply_to_conversation
Send an agent reply through a supported SingChat real-time inbox. This takes the conversation over from the AI and broadcasts the message to the visitor and agent inbox. Email, Telegram, and WhatsApp conversations are rejected before any change.
resolve_conversation
Mark a conversation as RESOLVED (closes it). The visitor's widget will no longer show it as active.
add_knowledge
Train the AI agent by adding a knowledge source. type='url' crawls a website (up to 50 pages); type='qa' stores a single question/answer pair. Ingestion is asynchronous, the source starts as PENDING; poll `list_knowledge` for READY status.
list_knowledge
List all knowledge documents for this workspace with their processing status (PENDING | PROCESSING | READY | FAILED) and chunk counts. Use this to check whether items added via add_knowledge have finished training.
search_knowledge
Semantic search over the workspace knowledge base. Returns the most relevant chunks (with source document title and similarity score) for a query. Only searches documents that have finished training (status READY).
configure_agent
Configure this workspace's AI support agent. All fields are optional, only the fields you pass are updated; the rest keep their current values. Call with no fields to just read back the current configuration. Does not touch or return any API keys.
