# Tool Discovery System
This MCP server uses a **discovery-based tool loading pattern** to reduce context overhead. Instead of loading all 35+ tools upfront, only the `discover_tools` meta-tool is exposed. Use it to find and load the specific tools needed for your task.
## Quick Reference
```
# List all categories
discover_tools({ mode: "list_categories" })
# Browse tools in a category
discover_tools({ mode: "browse", category: "messaging" })
# Search by natural language
discover_tools({ mode: "search", query: "send slack message" })
# Search by intent
discover_tools({ mode: "search", intent: "check team blockers" })
```
## Tool Categories
| Category | Tools | Use For |
| ----------- | ----- | ---------------------------------------- |
| `messaging` | 4 | Slack DMs, channel messages, user lookup |
| `whatsapp` | 8 | Message history, contacts, groups, media |
| `docs` | 11 | Google Slides, Sheets, presentations |
| `google` | 8 | Calendar, Gmail, Tasks (OAuth) |
| `apps` | 5 | Mini-app creation and management |
| `agents` | 3 | Agent context and handoff |
| `context` | 2 | Context management |
| `media` | 1 | Image/video generation |
| `system` | 2 | Health check, configuration |
## Workflow: Starting a Task
**Always discover tools before attempting to use them.**
1. Identify what you need to accomplish
2. Call `discover_tools` with appropriate mode
3. Review returned tool schemas
4. Execute the discovered tools
## Examples
### Example 1: Notify Team on Slack
**Task:** "Send a message to the team channel"
```
# Step 1: Find messaging tools
discover_tools({ mode: "search", query: "send slack channel message" })
# Returns: ai_first_slack_send_channel_message
# Step 2: Send the message
ai_first_slack_send_channel_message({ channel: "#orienter", message: "Quick update..." })
```
### Example 2: Find Upcoming Meetings
**Task:** "What meetings do I have this week?"
```
# Step 1: Find calendar tools
discover_tools({ mode: "browse", category: "google" })
# Returns: google_calendar_list_events
# Step 2: List events
google_calendar_list_events({ days: 7 })
```
### Example 3: Search WhatsApp History
**Task:** "Find messages about the project deadline"
```
# Step 1: Find WhatsApp tools
discover_tools({ mode: "browse", category: "whatsapp" })
# Returns: whatsapp_search_messages, whatsapp_get_conversation, etc.
# Step 2: Search messages
whatsapp_search_messages({ text: "project deadline" })
```
### Example 4: Update Presentation Text
**Task:** "Replace placeholders in the weekly slides"
```
# Step 1: Find Slides tools

ai_first_slides_update_text({ presentationUrl: "...", replacements: [{ placeholder: "{{WEEK_ENDING}}", replacement: "Jan 26" }] })
```
## Search Tips
- **Exact tool names** get highest scores: `discover_tools({ query: "ai_first_slack_send_channel_message" })`
- **Keywords** work well: `"blocker"`, `"sprint"`, `"slack"`, `"whatsapp"`
- **Intent phrases** find related tools: `"notify team about progress"`
- **Use limit** to reduce results: `discover_tools({ mode: "search", query: "message", limit: 5 })`
