# Well — AI Connector Well publishes 18 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/finance/well/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Finance](https://node8.ai/ai-connectors/finance/) # Well One graph over bank, invoicing, CRM and accounting tools Listed in Claude · 18 published tools · Community-listed [Claude connector docs](https://docs.wellapp.ai/mcp/introduction) [wellapp.ai](https://wellapp.ai/) Overview ## What Well does Well models the systems a small business already runs, banking, invoicing, CRM, email and accounting, as a single queryable graph and exposes that graph over MCP. Records carry provenance and can be traversed by relationship, so an invoice, the bank transaction that paid it and the vendor behind both can be joined even when they live in different products. Two bridge tools go further, letting Claude discover and invoke tools on other connected providers' own MCP servers without a second login, with Well holding and refreshing the credentials. Writes are idempotent, which matters when a retry would otherwise double-post an invoice. Installation runs over OAuth. ### Who it is for Founders and finance operators closing books across several disconnected tools. ### Tool surface The endpoint listed twenty five tools against a published count of eighteen, and the extra ones are the interesting part: alongside schema discovery and CRUD on companies, people and invoices sit reconciliation tools that diff bank activity against a QuickBooks register and post the gaps back. Availability ## Where Well is listed Well is listed in the Claude connectors directory only. Well has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Well publishes 18 tools to Claude, deeper than 65.6% of the 1,253 Claude-listed connectors. The median Claude-listed connector filed under Finance publishes 12, so this one runs 6 tools above its bucket's median and ranks 49th of 159 by tool count. It falls in the 11-20 tools band, which holds 22.5% of the Claude directory. ### Measured against the live endpoint A direct call to the endpoint returned 25 tools, 7 more than the 18 the listing publishes. Probed 2026-08-07. #### Tools the server actually returns - `well_get_schema` - `well_query_records` - `well_create_company` - `well_create_person` - `well_update_company` - `well_update_person` - `well_delete_company` - `well_delete_person` - `well_update_invoice` - `well_delete_invoice` - `well_add_contact_channel` - `well_remove_contact_channel` - `well_get_entity` - `well_list_connector_tools` - `well_invoke_connector_tool` - `well_create_invoice_from_data` - `well_list_workspaces` - `well_list_connectors` - `well_run_register_diff` - `well_resolve_reconciliation_task` - `well_resolve_register_diff_gap` - `well_get_investment_holdings` - `well_get_runway` - `well_get_cash_position` - `well_get_cost_structure` Well publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Well Verification Community-listed (61.5% of the Claude directory) Filed under Financial Services Endpoint `https://api.wellapp.ai/v1/mcp` Documentation [Publisher setup docs](https://docs.wellapp.ai/mcp/introduction) Published tools 18 · 11-20 tools band Depth rank in Finance 49 of 159 Snapshot August 2026 Well is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality. In the publisher's words ## How Well describes it > Well is a business context layer. It connects your bank, invoicing, CRM, email, and accounting tools, then models them as one living graph your agents can reach over MCP. Ask across every source at once. Read the schema and query invoices, companies, contacts, transactions, accounts, and journal entries, with relationship traversal and provenance on every record. Create and update companies, people, and invoices, all with idempotency so retries never double-apply. The part that stands out: one Well connection reaches every other tool. Two bridge tools let Claude discover and invoke the tools from any app connected to your workspace (Stripe, Qonto, Pennylane, Notion and 140+ more), with no second login. We hold and refresh the auth, so nothing breaks between sessions. Because the graph spans every tool, Claude answers questions no single app can. Match an invoice to a bank transaction to a vendor across different rails. Close your books from chat. Ask why the same vendor charged you twice, and get the answer. One click to install with OAuth. Nothing to paste. Quoted from the connector's own Claude directory listing as captured in August 2026. Node8 did not write it and does not vouch for it.
