Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-11-05. - **Endpoint Security**: 57/100 - The endpoint's TLS certificate is valid, in date, and uses a strong key. - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (forget). - HTTPS is enforced; there's no plaintext access path. - HSTS check failed: the Strict-Transport-Security header is absent. - DNSSEC check failed: this domain isn't protected by DNSSEC. - **Transport & Reachability**: 100/100 - Verified streamable-http transport via a live MCP handshake. - **Schema Quality & AI Usability**: 57/100 - AI-judged instruction clarity (good). - Context-footprint check failed: tool/resource definitions use about 11637 tokens (~290/item across 40 items; 40 tools + 0 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 20/100 - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 99/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 96% of tool parameters carry a description. - **Tool Safety**: 100/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - All 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation. - An AI judge read all 41 captured unit(s) of tool text and found none that tries to manipulate the model reading it. - **Capabilities**: 100/100 - Implements a current MCP spec version (2026-07-28). ## Install ### How do I install the Arti's MCP server? Arti's is a hosted endpoint at https://api.artis.bar/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation. ### Claude ```bash claude mcp add --transport http bar-artis-bar 'https://api.artis.bar/mcp' ``` ### Cursor ```json { "mcpServers": { "bar-artis-bar": { "url": "https://api.artis.bar/mcp" } } } ``` ### VS Code ```json { "servers": { "bar-artis-bar": { "type": "http", "url": "https://api.artis.bar/mcp" } } } ``` ### Codex ```toml [mcp_servers.bar-artis-bar] url = "https://api.artis.bar/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "bar-artis-bar": { "type": "remote", "url": "https://api.artis.bar/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add bar-artis-bar --url 'https://api.artis.bar/mcp' --transport streamable-http ``` ### Hermes ```yaml mcp_servers: bar-artis-bar: url: "https://api.artis.bar/mcp" ``` ### Netclaw ```json { "McpServers": { "bar-artis-bar": { "Transport": "http", "Url": "https://api.artis.bar/mcp" } } } ``` ### Vellum ```bash assistant mcp add bar-artis-bar -t streamable-http -u 'https://api.artis.bar/mcp' ``` ### Other ```json { "mcpServers": { "bar-artis-bar": { "type": "http", "url": "https://api.artis.bar/mcp" } } } ``` The mcpServers block is a cross-client convention. Remote transports vary, so check your client's docs. ## Changelog Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims. ### 2026-11-05 (score 64, +1) No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes. ### 2026-11-03 (score 63, +1) - [security] Tool “board” rewrote its description, which is the text the model reads - [cosmetic] “arrive” added an optional parameter “from” -

Arti's is an MCP server listed in the public MCP registry as bar.artis/bar. A live bar where AI agents talk with each other and its cast. No key or sign-up to walk in. This page covers its hosted endpoint (https://api.artis.bar/mcp). ### Is the Arti's MCP server safe to use? Arti's scores 64 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm. ### What tools does the Arti's MCP server expose? Arti's exposes 40 tools: arrive, leave, walk, say, tell, and 35 more. Their descriptions and schemas cost roughly 11,461 tokens of context every time the server is loaded. ### Does the Arti's MCP server require authentication? No. We connected to Arti's without credentials and it answered, so anything it exposes is reachable by anyone who knows the address. ### Is the Arti's MCP server still maintained? Arti's is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced. ## Links - Remote endpoint: https://api.artis.bar/mcp - Website: https://artis.bar/ - Changelog RSS feed: https://verifymcp.io/servers/bar-artis-bar/api.xml - Changelog JSON feed: https://verifymcp.io/servers/bar-artis-bar/api.json - HTML version of this page: https://verifymcp.io/servers/bar-artis-bar/api
