Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.05658 | $0.05658 |
| Opus 5.5 | $0.02263 | $0.02263 |
| Sonnet 5.5 | $0.01132 | $0.01132 |
| Haiku 4.5 | $0.00566 | $0.00566 |
Grade A, and why
homes-mcp CLAUDE.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Don't add IP-rotation or TLS-impersonation libraries. The whole design is "every request rides the user's own browser session via fetchproxy." Adding cycletls / curl-impersonate / Playwright would replace that with a s How it starts

CLAUDE.md — homes-mcp
Guidance for Claude working in this repo.
TL;DR
homes.com MCP server. Default and only transport: localhost WebSocket via @fetchproxy/server — the companion browser extension is installed separately rather than embedded. Every HTTP call to homes.com is dispatched through the user's signed-in Chrome tab — each request rides their existing session (cookies, TLS, JS context) exactly as if they'd clicked it themselves.
This is a "Pattern A" fetchproxy MCP (every call rides through fetchproxy), not "Pattern B" (one bootstrap call then direct fetch). homes.com gates traffic through AWS WAF at the session level, so the in-session routing has to be per-call.

homes_healthcheck |
tools/healthcheck.ts |
/robots.txt round-trip + bridge diagnostics via the shared registerBridgeHealthcheckTool (@chrischall/mcp-utils/fetchproxy); reports the 2.5.0 extension-link state (bridge.session_state / pending_pair_code / extension_connected) and error.kind incl. session_not_ready — a probe timeout while session_state is pair_pending, extension_disconnected, or no_session is re-kinded to session_not_ready, because the 18s probe deadline fires before fetchproxy's 30s session-ready wait and would otherwise report a pending pair code as a tab timeout; linked stays a timeout (the tab really is the problem) and not_listening stays a timeout so the no_role hint still wins |

homes_get_by_address |
tools/by-address.ts |
Structured smartsearch typeahead (POST /routes/res/consumer/smartsearch/autocomplete/) → slug GET /<address-slug>/ (collection or single RealEstateListing detail) → city/zip search fallback. Every candidate verified via realty-core addressMatch (whole-token street + numeric anchor) plus a unit guard. Surfaces matched_via: "typeahead" | "slug" | "search_fallback" on hits; { resolved: false, error } on miss; retryable status: "timeout" on a bridge timeout; retryable status: "blocked" when homes.com refused rather than missed (sign-in redirect / AWS WAF challenge / HTTP 403 / 429) — not a confirmed miss. |
read |
homes_resolve_addresses |
tools/resolve-addresses.ts |
Bulk homes_get_by_address — up to 100 { address, city, state, zip? }, same rungs/verification, input order preserved, per-row outcomes (property_hash→property_id) with row status: "resolved" | "unresolved" | "pending" | "blocked" — pending = cut off by the overall deadline, blocked = sign-in / WAF challenge / 403 / 429 (retry, not a miss). |

Bulk homes_get_property — up to 200 URLs, per-row errors captured, input order preserved (structured records only). |

homes_get_session_context |
tools/sessions.ts |
(local; shared session registry) — list all registered logical sessions + active_session_id |
read |
homes_register_session |
tools/sessions.ts |
(local; shared session registry) — register/refresh a session keyed by account_identity (required); optional auth_expires_at; mark_active (default false) registers-and-activates |
write (registry) |
homes_set_active_session |
tools/sessions.ts |
(local; shared session registry) — mark a session_id as the current account label (label only; does not change which account requests use) |

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
