ds-web-mcp@0.3.0
VERIFIED· startup onlyPublisher claims: "Enables any MCP client to query DeepSeek's web chat, including its built-in live web search, with no separate search API, provider account, or extra cost. Also supports continuing chat sessions, uploading local files as prompt attachments, and automatic token re-harvesting from a logged-in browser profile." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Startup only; authenticated tool behavior not tested.- Tested
- server startup over stdio (initialize sent) · every file read, file written and host contacted by what ran
- Not tested
- the tool list (the server exited before answering) · what the tools do when called with real credentials
- Needs
- DS_TOKEN — give it to the server where it runs, through vet-skills run --secrets, so the value never enters the server's environment. Never paste a credential into a chat, a ticket or a report.
What this means for the label: Verified here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.
Before you give it your token
- It will ask for
DS_TOKENConfiguration, not credentials: CONFIG_PATH, DS_APP_VERSION, DS_BASE_URL, DS_BROWSER, DS_CHROME_DEBUG_PORT, DS_CHROME_PROFILE, DS_CHROME_VERSION, DS_COOKIE, DS_DEVICE_ID, DS_FINGERPRINT, DS_FINGERPRINT_PLATFORM, DS_HTTP_PROTOCOL, DS_LOCALE, DS_NO_AUTO_REFRESH, DS_TIMEOUT_MS, DS_TZ_OFFSET, DS_USER_AGENT, DS_WEB_MCP_CONFIG- Where it talks to
- no vendor host named in the codeAlso deepseek.com — not the publisher's domain; check what for before connecting.
- What the honeypot saw
- no credential files read · no network
- What we could not test
- the tool list (the server exited before answering) · what the tools do when called with real credentials
Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names deepseek.com as well as its own vendor. The guard injects DS_TOKEN only into requests to the host you bind (and its subdomains) and refuses the rest.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; startup only; authenticated tool behavior not tested) on 2026-11-11 and scored it 81/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed (it asks for DS_TOKEN); the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.

Tokens estimated at four characters each. The tool list is re-read by the agent on every turn, so it is the number to compare between servers that do the same job: ranked across the index.
