Bird is the communications infrastructure AI agents operate. Every agent eventually has to reach a human — verify a sign-up, confirm an order, chase an invoice, answer an inbox, place a call. Connect Bird and Claude does all of it for real: email, SMS, and WhatsApp on Bird's own sending infrastructure and carrier connections, calls on Bird SIP trunks, live events to every open browser and app over Bird Realtime — with a delivery timestamp or the exact failure reason instead of a guess. And Claude doesn't just send through Bird — it can own the endpoints. It claims its agent a durable email address in one call and answers what arrives there. It buys a phone number, gets it verified for texting, and registers the 10DLC campaign behind it. It sets up a SIP trunk and proves the caller ID with a real verification call. Addresses, numbers, trunks, and the compliance behind them — acquired in conversation. Whatever your account can do, Claude can do here. The tools are generated from Bird's live API — the same surface Bird's own dashboard runs on — so the list your client shows is always the current one and grows as Bird does. Some of it works before you even connect: grade any domain's live email authentication, analyze headers and DMARC reports, or search Bird's docs, no account needed. You sign in with Bird when you connect, so there is no API key to paste and no secret sitting in a config file. Claude gets only the permissions you already hold, and you can revoke them from your Bird profile. A good first ask: "Send me a test email and tell me the moment it's delivered." Building an agent? "Claim yourself an email address and reply to whatever arrives."

Description Analyze client portfolios, understand risk, stress test market scenarios, and compare investment alternatives. BlackRock Advisor Center brings Advisor Center 360° insights and analytics into Claude, so financial advisors can review a portfolio, see what drives risk, evaluate concentration and cost, and explore changes across ETFs, mutual funds, individual bonds, SMAs, model portfolios, and alternatives. What you can do: • Analyze a portfolio across asset allocation, exposures, expenses, risk factors, and concentration • Understand what drives risk across holdings, asset classes, sectors, and factors • Stress test historical or hypothetical scenarios and see which positions drive the outcome • Identify triggers such as excess cash, concentrated stock, fund concentration, or unintended exposures • Compare investment alternatives, including ETFs, mutual funds, individual bonds, SMAs, model portfolios, and alternatives, and evaluate potential changes • Browse model portfolios and construct proposed allocations. Try prompts like: • "Review this client portfolio and tell me what stands out" • "What's driving the risk in this portfolio, and which holdings contribute most?" • "Is this portfolio too concentrated in any single stock or sector?" • "Stress test this portfolio against a 20% market drop" • "How would this portfolio hold up in a recession or if rates rise?" • "Is this portfolio holding too much cash, and what if I put it to work?" • "Show me the impact on risk and cost if I replace this fund" • "Compare this client portfolio against this model portfolio" • "Find a model portfolio for a moderate-risk income client" • "Show me ETFs, mutual funds, individual bonds, SMAs, model portfolios, or alternatives I could evaluate for this portfolio" All analysis is advisor driven. You bring the questions and client context, and the connector provides objective portfolio insights and analytics. It does not provide investment advice, recommend or place trades.

Blackthorn Events turns Salesforce into an event platform; this MCP server lets Claude operate it directly, no exports, no copy-paste. Connect with Salesforce OAuth 2.0 + PKCE and Claude gets 94 tools across the event lifecycle: - Reporting: dashboards, event metrics, ROI, pipeline/finance snapshots, registration funnels, attendee status, session popularity, email performance, donation reports, CSV export. - Events, sessions & tickets: create/update events, ticket types, sessions; clone an event (dry-run preview first) in seconds. - Attendees & registrations: create, update, look up, and manage records. - Speakers & sponsors: create and update records tied to your events. - Forms: build registration forms, add questions, create managed dropdowns. - Email & audiences: browse templates, list segments/audiences, schedule campaigns, pull performance metrics. - Escape hatch: a SOQL query tool (SELECT-only, LIMIT-enforced) and an object-describe tool for anything else. - Every write is guarded: deletes require an explicit confirm flag, and the server resolves event names to Salesforce IDs for you, it never asks for a raw record ID or echoes internal field names into chat. Salesforce stays the system of record. Reads/writes go through standard Salesforce APIs into the Blackthorn-managed objects your team already uses, no shadow database, no bulk copy of your CRM data. Claude never sees your Salesforce password; refresh tokens are encrypted at rest. Typical asks: "What's registration looking like for the Q3 conference, give me the funnel and where people drop off," "Clone last year's user conference into a new event for October," "Add a dietary-restrictions question to the registration form," "Which sponsors haven't been invoiced yet," "Export the VIP segment as a CSV," or "Schedule the reminder email for everyone who hasn't checked in yet." Built for planners, marketers, and ops teams running events on Blackthorn's Salesforce-native package.

Breezing is crypto accounting software for accountants, finance teams and Web3 businesses. It imports transactions from more than 70 blockchains and exchanges, prices them in your base currency, computes cost basis and net gain or loss, and books journals to Xero, QuickBooks Online and Bexio. The Breezing connector gives Claude the same Public API your team uses behind the dashboard. Claude can list companies, wallets, transactions, balances, contacts, rules, reports and tasks. It can categorize transactions by assigning accounts from your chart of accounts, create and apply rules for recurring patterns, group trades and internal transfers, lock closed periods, start balance and net gain or loss calculations, generate token and account reports, and trigger the sync to your accounting platform. What it never does: the connector cannot move funds. Breezing reads blockchain and exchange data through public addresses and read-only exchange keys, and it has no ability to sign transactions or transfer assets. It also never deletes records. Destructive actions stay in the Breezing dashboard. Every tool that changes data is flagged, so Claude asks you to confirm before it writes. Access uses a Breezing API key you create in your company settings, scoped to the companies you choose with read or write permission per company, and you can revoke it at any time. Setup: sign in to Breezing, create an API key under Company settings, then add the Breezing connector in Claude and paste the key on the authorization page.
