Personalbrain is a remote MCP server that gives an AI agent 83 tools, among them brain_account_statement, brain_account_statement_infographic, brain_add_file_attachment. It answers at https://personal-brain.fastmcp.app/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
FastMCP server for TheBrain API — AI access to a personal knowledge graph, Tollbooth-monetized
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
brain_account_statement | Generate a patron's account statement at this operator. Returns the patron's purchase history, active credit tranches, per-tool usage breakdown, and recent daily usage logs. This is the patron's spending account — not the operator's Authori Inputs: npub, dpop_token, days |
brain_account_statement_infographic | Generate a visual SVG infographic of your account statement. Returns the same data as account_statement, rendered as a dark-themed SVG graphic with balance hero, metrics cards, health gauge, tranche table, and tool usage breakdown. Costs 1 Inputs: npub, dpop_token, days |
brain_add_file_attachment | Add a file attachment to a thought. Requires npub for credit billing. Inputs: thought_id, file_path, brain_id, file_name, npub, dpop_token |
brain_add_url_attachment | Add a URL attachment to a thought. Requires npub for credit billing. Inputs: thought_id, url, brain_id, name, npub, dpop_token |
brain_adoption_status | Check this operator's adoption-request status at a chosen Authority. Free. Polls the Authority MCP-to-MCP for the status of this operator's request (pending / approved / rejected / provisioned). Inputs: authority_npub, dpop_token |
brain_append_to_note | Append content to an existing note. Requires npub for credit billing. Note style. Prefer plain prose. Reserve bold for rare critical flags only — a ⚠️ caution, an unconfirmed-status note — never for ordinary emphasis, labels, or whole claus Inputs: thought_id, markdown, brain_id, npub, dpop_token |
brain_brain_query | Primary tool for pattern-based operations on TheBrain. Requires npub for credit billing. Accepts BrainQuery (BQL) -- a Cypher subset supporting MATCH, WHERE, CREATE, SET, MERGE, DELETE, and RETURN. ⚠️ Name-based matching (MATCH by name, WHE Inputs: query, brain_id, confirm, npub, dpop_token |
brain_check_authority_balance | Check this operator's tax balance at the Authority. Returns the sats available for certifying patron credit purchases. When this balance reaches zero, patron top-ups cannot be certified and the operator must call purchase_credits on the Aut |
brain_check_balance | Check a patron's credit balance at this operator. This is the patron's spending balance — credits purchased via Lightning for tool calls at this operator. For the operator's own balance at the Authority (needed to certify patron purchases), Inputs: npub, dpop_token |
brain_check_payment | Check the payment status of a Lightning invoice. Call after paying the invoice from purchase_credits. Free — no credits required. Proof of npub ownership is required to prevent credit-grant front-running by an observer of the invoice ID. Inputs: invoice_id, npub, dpop_token |
brain_check_price | Preview the effective cost of a tool call. Shows the base cost and any constraint effects (discounts, free trials, surge pricing). Free — no credits required. Inputs: tool_id, npub, dpop_token, tool_kwargs |
brain_check_proof_status | Check whether a previously-cached dpop_token is still valid. Mirrors ``check_oauth_status`` for the npub-proof flow: a calling agent can ask "will my next paid call accept this dpop_token?" before burning credits on a guaranteed failure. Fr Inputs: patron_npub, dpop_token |
brain_create_link | Create a relationship between two thoughts by ID. Requires npub for credit billing. Inputs: thought_id_a, thought_id_b, relation, brain_id, name, color |
brain_create_or_update_note | Create or update a note with markdown content. Requires npub for credit billing. Note style. Prefer plain prose. Reserve bold for rare critical flags only — a ⚠️ caution, an unconfirmed-status note — never for ordinary emphasis, labels, or Inputs: thought_id, markdown, brain_id, npub, dpop_token |
brain_create_thought | Create a new thought with optional type, color, label, and parent link. Requires npub for credit billing. Inputs: name, brain_id, kind, label, foreground_color, background_color |
brain_delete_attachment | Delete an attachment. Requires npub for credit billing. Inputs: attachment_id, brain_id, npub, dpop_token |
brain_delete_coupon | Delete a coupon. Cascades to all patron redemptions. Any chain step referencing the deleted coupon_id becomes a no-op (the constraint returns neutral on unknown ids) — the Studio surfaces orphan references as warnings. RESTRICTED to operato Inputs: coupon_id, dpop_token |
brain_delete_link | Permanently delete a link by ID. Cannot be undone. Requires npub for credit billing. Inputs: link_id, brain_id, npub, dpop_token |
brain_delete_operator_credential | Remove a single operator secret field. Deletes one key from the operator's encrypted credential blob without touching the others — the field-level counterpart to ``forget_credentials``, which wipes the whole row. Use it to retire a leftover Inputs: field, dpop_token |
brain_delete_patron_credential | Remove a single patron credential field. Deletes one field from stored credentials without affecting other fields. Free. Proof of npub ownership is required — this is a write to the patron's sensitive credential vault. Inputs: npub, dpop_token, field |
brain_delete_thought | Permanently delete a thought by ID. Cannot be undone. Requires npub for credit billing. Inputs: thought_id, brain_id, confirm, npub, dpop_token |
brain_event_for_person | Create an Event+Person+Day in one action. Requires npub for credit billing. Inputs: date, person, event_name, notes, brain_id, npub |
brain_forget_coupon | Remove a coupon from this patron's redemption list. Cosmetic only — the coupon itself still exists at the operator, and the patron can re-redeem the same code later while the window allows. Free — requires proof of ``npub``. Inputs: npub, coupon_id, dpop_token |
brain_forget_credentials | Delete vaulted credentials for a specific service and npub. For operator credentials, pass the operator's own npub. For patron credentials, pass the patron's npub. Always requires proof of npub ownership — a deletion is as destructive as a Inputs: service, npub, dpop_token |
brain_get_attachment | Get metadata about an attachment. Requires npub for credit billing. Inputs: attachment_id, brain_id, npub, dpop_token |
brain_get_attachment_content | Get the binary content of an attachment. Requires npub for credit billing. Inputs: attachment_id, brain_id, save_to_path, npub, dpop_token |

brain_get_nostr_profile | Read an npub's public Nostr profile (NIP-01 kind-0 metadata). Free, no proof — the data is already public on relays. Returns the latest metadata fields (name, display_name, about, picture, banner, nip05, website, lud16) or an empty profile Inputs: npub |
brain_get_notarization_proof | Generate a Merkle inclusion proof that a patron's balance was included in a Bitcoin-notarized snapshot. Inputs: notarization_id, npub |
brain_get_note | Get the note content for a thought. Requires npub for credit billing. Inputs: thought_id, brain_id, format, npub, dpop_token |
brain_get_operator_onboarding_status | Report this operator's configuration readiness. Shows which operator settings are configured, which are missing, and how to deliver each missing value. For patron-level credential status, use get_patron_onboarding_status instead. Free. |
brain_get_patron_credential_fields | List stored patron credential field names (not values). Returns the names of fields stored for a patron, plus each field's ``delivered_at`` ISO-8601 timestamp when known (null for secrets vaulted before timestamps were recorded). Values are Inputs: npub, dpop_token |
brain_get_patron_onboarding_status | Report a patron's credential readiness for this operator. For set-once services (eXcalibur, TheBrain), shows which patron secrets are configured and which are missing. For dynamic/OAuth2 services (Schwab), reports that no patron credentials Inputs: patron_npub, dpop_token |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://personal-brain.fastmcp.app/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
