Available tools 25

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

prepare

prepare_portal_fill

Map intake facts to a fill_fields payload for TRS or Companies House PSC. Secrets (auth code) are listed but never filled. Call after Owner login; align labels with list_fillable_fields. Never maps the Trust as a PSC organisation.

prepare_submit_confirmation

Create a one-time confirmation token required before confirm_and_submit. Show the token to the human Owner; do not submit without it.

book

search_book

REQUIRED before substantive Protocol answers. Search approved Blackbook Protocol passages and return cited excerpts. Prefer Protocol vocabulary from hits over generic UK legal advice. Returns ranked results plus the educational boundary.

companies

get_companies_house_guidance

Retrieve approved Companies House / PSC / WebFiling guidance. PSC filings name individuals (trustees), never the Trust itself.

confirm

confirm_and_submit

Submit the current portal form only after the human provides a valid one-time confirmationToken from prepare_submit_confirmation. This can file on a government portal.

draft

draft_form_answers

Draft preparation notes for TRS, IHT100, IHT400, and related professional-review questions from a completed intake. Label as a Protocol guide for solicitor execution.

end

end_browser_session

Tear down the assisted browser session. No credentials are persisted. Safe to call more than once for the same id after expiry.

explain

explain_current_screen

Summarise the current portal page: URL, text excerpt, fillable fields, Protocol hint, signedInLikely.

fill

fill_fields

Fill non-secret form fields (label/placeholder/name). Never passwords, OTPs, or Companies House auth codes.

fillable

list_fillable_fields

Inventory visible non-secret form controls (label/name/type) on the current portal page. Use to align prepare_portal_fill keys.

generate

generate_review_bundle

Generate a cited professional-review bundle from a completed intake for the Owner to take to a solicitor or CTA.

hmrc

get_hmrc_guidance

Retrieve approved GOV.UK/HMRC trust and inheritance-tax guidance by topic. Returns a title, official URL, and short summary. Not a live scrape of GOV.UK.

implementation

list_implementation_modes

List Owner choices: self_serve (own browser + guidance) vs assisted (Browserbase live view + optional fill). Ask before starting co-pilot.

legal

get_legal_boundary

Return the mandatory educational / non-advice boundary statement. Call when the Owner asks if this is legal advice.

module

get_module_playbook

REQUIRED when coaching setup. Return the ordered Protocol checklist for a module. For 95/5 / share transfer into the Trust use equity_95_5 (not a freestyle solicitor checklist). Modules: vault, trs, equity_95_5, psc, banking, ip, philosophy, legacy, property.

modules

list_modules

List available Protocol advisor modules in coaching order.

open

open_portal

Navigate the assisted session to an allowlisted portal: trs, trs_manage, companies_house_webfiling, or companies_house_psc.

Pause for Owner login, CAPTCHA, 2FA, or review in the Browserbase live view. Never ask the Owner to paste passwords into chat.

risk

list_risk_flags

Return legal, tax, and practical red flags detected from customer facts (settlor-as-beneficiary, lender consent, offshore, time pressure).

self

get_self_serve_portal

Self-serve path: return the official portal URL plus Protocol checklist for the Owner’s own browser. Present portalUrl as a clickable markdown link (MCP cannot launch local browsers). Do not start Browserbase.

skill

skills

list_skills

List Protocol Architect workflow skills (Vault, TRS, 95/5, PSC, portal co-pilot). Call when the Owner asks how to set something up; then get_skill for the matching workflow.

start

start_browser_session

ASSISTED mode only. Start a fresh ephemeral Browserbase (or mock) co-pilot session. Returns liveViewUrl — no purchaser email. If Owner prefers their own browser, use get_self_serve_portal instead.

trust

run_trust_intake

Validate a structured trust setup intake and return missing facts, Protocol warnings, and next modules. Call before drafting forms or opening portals.

wait

wait_for_user_ready

After request_user_action(login|2fa), poll until the page leaves the sign-in surface (or timeout). Then continue fill.

How do I connect Blackbook Protocol Advisor?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Blackbook Protocol Advisor need an API key?

No. Blackbook Protocol Advisor completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 25 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Blackbook Protocol Advisor?

It answers our handshake in 335 ms on average, which is faster than 53% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
