A side-by-side look at the AllMCPs Server and Slack MCP Server MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose AllMCPs Server for aggregators work over a hosted endpoint; choose Slack MCP Server for communication as a local process. You can also run both side by side in one mcpServers block.

search_mcp_serversSearch the AllMCPs directory for Model Context Protocol (MCP) servers by keyword or category.get_mcp_install_configGet the exact claude_desktop_config.json setup snippet and documentation for a specific MCP server by ID.recommend_mcp_stackRecommend a curated multi-tool MCP server stack for a specific developer role or workflow (e.g. "fullstack", "data science", "devops").list_mcp_categoriesList all categories available in the AllMCPs directory along with server counts.get_boost_pricingGet pricing and features for boosting / featuring an MCP server on AllMCPs.com.boost_mcp_serverInitiate a sponsorship / boost order for an MCP server by ID, returning a Stripe checkout session URL and x402 invoice.get_boost_statusCheck current boost status, verified badge level, and sponsorship expiration for an MCP server by ID.submit_mcp_serverProgrammatically submit a new MCP server repository to AllMCPs.com for indexing and review. Supports the same optional enrichment fields as the human submission form — fill in whichever you can confidently determine from the repository (README, package.json, code) to produce a fully flushed-out listing. Omit anything you are not confident about rather than guessing; all enrichment fields are optional and unrecognized enum values are simply dropped, not rejected.verify_mcp_claimVerify ownership and claim an MCP server listing by checking GitHub README badge, website badge, or DNS TXT record. Works two ways: (1) fully unattended — pass `agentToken` from confirm_mcp_agent (or set an `Authorization: Bearer <token>` header if your client supports it), no human sign-in needed; or (2) if called with neither, requires the caller to already have an active AllMCPs browser session. Unattended agents should use register_mcp_agent + confirm_mcp_agent first.register_mcp_agentStart unattended-agent registration: emails a 6-digit confirmation code to the given address. Follow up with confirm_mcp_agent to exchange the code for a bearer token, which unlocks verify_mcp_claim (and future privileged tools) without ever needing a human to sign in via browser.confirm_mcp_agentExchange the 6-digit code emailed by register_mcp_agent for a durable bearer token (90-day TTL). Pass the returned token as `agentToken` on verify_mcp_claim, or set it as an `Authorization: Bearer <token>` header on subsequent MCP requests if your client supports that.slack_token_statusCheck token health, age, auto-refresh status, and cache statsslack_health_checkCheck if Slack tokens are valid and show authentication statusslack_refresh_tokensForce refresh tokens by extracting from Chrome (requires Slack tab open in Chrome)slack_list_conversationsList all DMs and channels with user names resolved. Uses cached DMs by default for speed.slack_conversations_historyGet messages from a channel or DM with user names resolvedslack_get_full_conversationExport FULL conversation history with all messages, threads, and user names.
