deep-email 0.2.0

MCP server that gives AI agents deep understanding of your email

Deepmail

Your agent can search your email. It can't understand it.

Gmail MCP servers let agents read individual messages. But understanding email — knowing who matters, what relationships exist, what's happening in your life and business — requires investigation, cross-referencing, and memory. Agents can't do that in a single search.

Deepmail gives your AI agent 10 tools to investigate, analyze, and remember your email. It builds persistent knowledge that survives across sessions — so your agent actually knows you.

What your agent can do with Deepmail

You: "Who are my investors?"

Agent searches your Gmail for term sheets, fund communications, board emails.
Agent reads specific emails to understand deal details.
Agent cross-references names across rounds.
Agent builds a complete investor table — firms, key contacts, amounts, dates.

Next session, your agent already knows. No re-searching.

Install

pip install deep-email

Or run directly:

uvx deep-email setup

Configure your agent

Add to your project's .mcp.json:

{
  "mcpServers": {
    "deepmail": {
      "type": "stdio",
      "command": "uvx",
      "args": ["deep-email"]
    }
  }
}

Or use the CLI:

deep-email init   # writes .mcp.json for you

Install the skill (teaches your agent how to use the tools)

npx skills add dennisonbertram/deepmail

Works with Claude Code, Cursor, Codex, GitHub Copilot, Windsurf, Gemini CLI, and 40+ other agents.

Google Cloud Setup

Deepmail needs read-only access to your Gmail. You'll need a Google Cloud project with OAuth credentials (~10 min, one-time).

Step-by-step setup

1. Create a Google Cloud Project

• Go to Google Cloud Console
• Select a project → New Project → name it anything → Create

2. Enable the Gmail API

• Go to Gmail API
• Click Enable

3. Configure OAuth Consent Screen

• Go to OAuth consent screen
• Choose External → Create
• App name: anything. Support email: yours. Developer contact: yours.
• Scopes → Add or Remove Scopes → find gmail.readonly → check it → Update → Save
• Test users → Add Users → add your email → Save

Note: Your app starts in "Testing" mode. Tokens expire every 7 days — re-run deep-email auth when they do. For non-expiring tokens, submit your app for verification on the consent screen (optional for personal use).

4. Create Credentials

• Go to Credentials
• Create Credentials → OAuth client ID → Desktop app → Create
• Copy the Client ID

5. Set the credential

export GOOGLE_CLIENT_ID="your-id.apps.googleusercontent.com"

Or add to ~/.zshrc / ~/.bashrc for persistence.

Authenticate

deep-email auth

Opens your browser for Google consent. One-time setup. Read-only access — Deepmail never sends, modifies, or deletes email.

Tools

Tool	What it does
search_emails(query)	Search Gmail — returns sender, date, subject, snippet
read_email(message_id)	Read the full body of a specific email
build_profile(query)	Deep investigation — extracts people, builds profiles
build_status()	Check progress of a running investigation
get_candidates()	Review extracted candidates from latest investigation
who_is(person)	Look up a person from cached knowledge
about_me(topic)	What the agent knows about you, by topic
profile_health()	Check how fresh the cached knowledge is
reset_profile(confirm)	Wipe cached knowledge and start fresh
check_auth()	Verify Gmail connection

How it works

1. Your agent reads the skill and learns how to investigate email topics
2. It searches your Gmail using search_emails — following leads, reading full emails when needed
3. It builds profiles using build_profile — extracting people, relationships, and context
4. Knowledge persists — who_is and about_me return cached results instantly in future sessions
5. It gets smarter — each investigation adds to the persistent knowledge base

All data stays on your machine. The MCP server runs locally. No cloud storage, no telemetry.

Examples

"Figure out my investors" — Agent searches for term sheets, fund emails, board communications. Builds a table of investors across rounds with key contacts and amounts.

"Who's on my team?" — Agent searches internal comms, standup emails, shared docs. Maps your org with roles and last-contact dates.

"Tell me about my relationship with [person]" — Agent searches all correspondence, synthesizes a relationship summary with timeline.

"What should I know before my meeting with [person]?" — Agent pulls recent threads, open items, relationship context.
