Category & Scope
Tools & Capabilities Breakdown
Founders Os Tools (102)
ping
Test tool — returns pong.
get_version
Returns the running version of @ourthinktank/founders-os, the rendering contract version (used to detect plugin/server drift), how the connector was launched (launchMethod: npx | global | local | unknown) with a tailored howToUpdate string, the release channel (channel: stable | prerelease), the published head of that channel, and the database schema status (dbSchemaStatus: current | behind | ahead | untracked | unknown) with a howToUpdateDb step when action is needed. Version comparison is semver-aware and channel-aware: stable builds compare against the `latest` tag, prerelease builds against the `next` tag, so a prerelease that is ahead of stable is NOT reported as an update. versionStatus is one of current | update-available | ahead | unknown; updateAvailable is true only when a genuinely newer version exists on your channel (with updateTo naming it). Call at session start; if updateAvailable is true relay current vs updateTo and the howToUpdate step, and if dbSchemaStatus is behind or untracked relay the howToUpdateDb step.
get_usage_guide
Returns a detailed guide on how to use Founders OS - covering all six domains (CRM, Tasks, Tags, Finance, Feeds, Memory), surface tools, search protocols, common workflows, and tips. Call this when uncertain about how to approach a task.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Founders Os is categorized under Workplace & Productivity and uses a local stdio subprocess. In contrast, Google Workspace MCP belongs to Workplace & Productivity using local stdio subprocess. Select Founders Os when you need capabilities focused on workplace & productivity and Google Workspace MCP when you require tools for workplace & productivity.
Returns example prompts and workflows organized by domain (CRM, Tasks, Finance, Feeds, Memory, Surfaces). Call this when a user asks 'what can you do?', 'show me what I can do', 'help me get started', or wants to explore what Founders OS offers. Lighter than the full usage guide - focused on natural-language examples rather than technical reference.
list_demos
Returns available interactive demo walkthroughs bundled with Founders OS. When called without a name, returns a summary list of available demos. When called with a demo name, returns the full script (with shared presentation rules prepended) so the AI agent can run it directly. Call this when a user asks about demos, wants to explore features, or is onboarding.
add_customer
Create a new customer record. Customers are organizations or individuals that your business works with or is pursuing. If similar customers already exist, a `conflict` response is returned with options to use an existing record or create a new one. Pass skip_duplicate_check=true to bypass this on retry.
get_customer
Get a single customer with their contacts, recent interactions, and open tasks.
update_customer
Update fields on an existing customer record.
search_customers
Search customers by name, notes, city, state, or tags. Returns matching customers with summary info.
list_customers
List customers with optional filters. Returns paginated results with summary info. Response includes a render field with tiered rendering guidance - check it before composing your reply.
remove_customer
Remove a customer by archiving (sets phase to inactive, recoverable) or permanently deleting. On first call, returns a `conflict` with ARCHIVE / DELETE / CANCEL options. Pass mode after the user decides. Contacts cascade on delete; history is preserved on archive.
add_contact
Add a contact person to a customer organization. Contacts are individuals you interact with at that company.

Google Workspace MCP Tools (123)
start_google_auth
Manually initiate Google OAuth authentication flow.
NOTE: This is a legacy OAuth 2.0 tool and is disabled when OAuth 2.1 is enabled.
The authentication system automatically handles credential checks and prompts for
authentication when needed. Only use this tool if:
1. You need to re-authenticate with different credentials
2. You want to proactively authenticate before using other tools
3. The automatic authentication flow failed and you need to retry
In most cases, simply try calling the Google Workspace tool you need - it will
automatically handle authentication if required.
search_gmail_messages
Searches messages in a user's Gmail account based on a query.
Returns both Message IDs and Thread IDs for each found message, along with Gmail web interface links for manual verification.
Supports pagination via page_token parameter.
get_gmail_message_content
Retrieves the full content (subject, sender, recipients, body) of a specific Gmail message.
Bodies are returned inline and truncated at 20,000 characters. Set full=True to
get the complete, untruncated message instead: it is exported to disk and the
response carries a short-lived download URL (HTTP transport) or file path (stdio
transport) rather than the body, so large messages never stream through the model
context. Stateless deployments have no file storage, so there full=True returns the
untruncated body inline.
get_gmail_messages_content_batch
Retrieves the content of multiple Gmail messages in a single batch request.
Supports up to 25 messages per batch to prevent SSL connection exhaustion.
get_gmail_attachment_content
Downloads an email attachment and saves it to local disk.
In stdio mode, returns the local file path for direct access.
In HTTP mode, returns a temporary download URL (valid for 1 hour).
May re-fetch message metadata to resolve filename and MIME type.
send_gmail_message
Sends an email using the user's Gmail account. Supports new emails, replies, and
forwards, with optional attachments. Supports Gmail's "Send As" feature to send
from configured alias addresses.
To forward an existing message, pass forward_message_id. The original subject,
body (quoted with a "Forwarded message" header), and attachments are carried over.
In forward mode, body (if any) is prepended as a note and subject is optional.
Threading, reply, and signature options do not apply when forwarding.
THIS TOOL SENDS IMMEDIATELY AND CANNOT SCHEDULE. Gmail's REST API exposes no
send-time parameter; Schedule send is a web-UI feature with no API equivalent,
so no argument to this tool can defer delivery. Never tell a user a message
was scheduled. For "prepare now, deliver later", create a draft with
draft_gmail_message. An external scheduler must retain the message data to
create and send a new message via send_gmail_message at the chosen time, or
call users.drafts.send with the draft ID returned by draft_gmail_message.
Alternatively, let the user schedule that draft in the Gmail UI.
draft_gmail_message
Creates a draft email in the user's Gmail account. Supports both new drafts and reply drafts with optional attachments.
Supports Gmail's "Send As" feature to draft from configured alias addresses.
SCHEDULED SEND IS NOT AVAILABLE. Gmail's REST API exposes no send-time
parameter; the Schedule send feature is web-UI only, and a message cannot be
placed in the Scheduled folder through the API. Do not claim a message was
scheduled. To deliver at a chosen time, create a draft with
draft_gmail_message. An external scheduler must retain the message data to
create and send a new message via send_gmail_message then, or call
users.drafts.send with the draft ID returned by draft_gmail_message.
Alternatively, let the user schedule the draft in the Gmail UI.
get_gmail_thread_content
Retrieves the complete content of a Gmail conversation thread, including all messages.
Optionally also returns structured ownership analysis so a caller can
determine who sent the last message and who owes whom a response without
re-parsing the formatted string or making a second tool call.
get_gmail_threads_content_batch
Retrieves the content of multiple Gmail threads in a single batch request.
Supports up to 25 threads per batch to prevent SSL connection exhaustion.
list_gmail_labels
Lists labels in the user's Gmail account.
manage_gmail_label
Manages Gmail labels: create, update, or delete labels.
list_gmail_filters
Lists all Gmail filters configured in the user's mailbox.
