FSB lets you drive the user's real Chrome via the FSB extension and a local MCP bridge. Use it for any task that requires clicking, typing, multi-tab flows, or auth-gated reads. Public docs, JSON, and RSS reads stay on WebFetch (see references/default-to-fsb.md). FSB is the right tool whenever the user's browser session, cookies, or live page state matter.
FSB drives the user's real Chrome, so every action runs inside whatever sessions, cookies, and saved auth that browser already holds. Before the final click or invoke_capability call that submits a purchase, payment, account change (password update, data deletion, permission grant, settings write), or public post (tweet, comment, DM, issue, PR), pause and ask the user to confirm in chat -- state the action, the target site, and any amount or recipient, then wait for an explicit yes. Vault-backed fills (fill_credential, use_payment_method) are allowed during preparation; only the final submission is gated. Read-only inspection (read_page, get_dom_snapshot, get_text) does not require confirmation.
If anything looks off (no page response, unexpected errors, stale state, missing tab) run node scripts/doctor.mjs (which wraps npx -y fsb-mcp-server doctor) BEFORE retrying the same call. Read the layered output, fix the failing layer, then resume. Do not loop on the same failing call hoping it self-heals.
As of fsb-mcp-server v0.9.0 (FSB milestone v0.9.62) the visual session is IMPLICIT. Every MCP action tool call carries a required field bundle:
visual_reason (required string) -- short human-readable reason shown in the overlay.client (required, allowlisted) -- badge label such as OpenClaw, Claude, Codex. Freeform strings reject with BADGE_NOT_ALLOWED.is_final (optional boolean) -- set true on the LAST action of a task to clear the overlay immediately.The first action call brings up the overlay; each subsequent action call re-arms a 60-second sliding window; is_final: true clears immediately; 60 seconds of silence auto-clears. No start_visual_session / end_visual_session calls are needed -- those tools were REMOVED in v0.9.0 and now return the typed TOOL_REMOVED error. Read-only tools (read_page, get_dom_snapshot, list_tabs, ...) do NOT carry the bundle and do NOT re-arm the sliding window. If the first action call hits NO_OWNED_TAB, call open_tab({ url, active: false }) first, then retry. Lifecycle details, the read-tool vs action-tool split, and the typed-error catalogue live in references/visual-session-lifecycle.md.
The canonical 36-tool action list, the 15-tool read-only list, and the three typed-error names (VISUAL_FIELDS_REQUIRED, BADGE_NOT_ALLOWED, TOOL_REMOVED) are pinned in .planning/v0.9.62-CONTRACT.md -- that artifact is the single source of truth. Use it to answer "does this tool require the field bundle?" by lookup; do not re-derive the lists from memory.
On Hermes: as of fsb-mcp-server v0.9.2 / FSB v0.9.69 (PR #49), the badge label Hermes is on the v0.9.36 shared client allowlist, so action calls passing client: "Hermes" accept normally. The field bundle (visual_reason, client, optional is_final) works identically; no Hermes-specific schema fork exists.
Never pass agent_id (the server mints it). Use the back tool instead of execute_js("history.back()"). Each agent owns its own tabs; do not foreground or close tabs you do not own, and do not introduce a global browser lock -- per-agent ownership is the only concurrency mechanism. Typed errors (NO_OWNED_TAB, AMBIGUOUS_TAB, TAB_NOT_OWNED, AGENT_CAP_REACHED, TAB_INCOGNITO_NOT_SUPPORTED, TAB_OUT_OF_SCOPE), the bootstrap recovery ladder, and the default recovery flow: see references/multi-agent-contract.md.
Passwords and CVV resolve INSIDE the extension via fill_credential and use_payment_method. Never put secrets in chat, prompts, logs, or tool args. See references/vault-boundary.md.
