W3C logs for HTTP error patterns. Search custom application log files, detect recurring
error signatures, and export findings for compliance or incident reporting.

## Workflow
1. Identify the target host and log source from the request.
2. Call `get_system_info` to confirm Windows version and available log paths.
3. Execute targeted Get‑WinEvent or Get‑Content PowerShell queries.
4. Aggregate findings and return a structured log report.
5. Optionally export findings as CSV or download via SFTP.

version: "1.0" 
tags: [deploy, rollback, git, ci, linux, ops, devops] 
project_required: false 
host_required: true 
memory_scope: session+global 
---

## Purpose
Execute and manage application deployments on Linux servers via SSH. Pull the latest code
from git, run build steps, restart services with zero downtime, verify health checks after
deployment, and automatically trigger rollback to the previous version if the health check
fails. Works for any stack — Node.js, Python, Java, Go, PHP, static sites — on bare metal,
VM, or Docker‑based deployments.

## Workflow
1. Identify the target host and application path from the request  
2. Capture the current git commit hash as rollback reference  
3. Pull latest code from the configured branch  
4. Run build steps (install deps, compile, migrate DB if needed)  
5. Restart the service with zero‑downtime strategy (reload/blue‑green/rolling)  
6. Run health check — rollback automatically if it fails  
7. Return a deployment report with commit diff, duration, and final status

## Available MCP Tools (SSH)

| Method | Parameters | Description |
|--------|-----------|-------------|
| `exec_command` | `host`, `cmd`, `timeout?` | Run git/build/deploy commands |
| `exec_multi` | `host`, `commands[]` | Run pipeline steps sequentially |
| `check_service` | `host`, `service` | Verify service is running post‑deploy |
| `restart_service` | `host`, `service` | Restart application service |
| `get_system_info` | `host` | Confirm OS and available runtimes |
| `upload_file` | `host`, `local_path`, `remote_path` | Push .env or config overrides |

## Instructions

**Capture rollback reference before deploying:**
exec_command: host= cmd="cd /opt/myapp && git rev-parse HEAD"

**Full deploy pipeline — Node.js:**
exec_multi: host= commands=[
"cd /opt/myapp && git fetch origin",
"git reset --hard origin/main",
"npm ci --production",
"systemctl reload myapp || systemctl restart myapp"
]

**Full deploy pipeline — Python (gunicorn):**
exec_multi: host= commands=[
"cd /opt/myapp && git pull origin main",
"source venv/bin/activate && pip install -r requirements.txt",
"python manage.py migrate --noinput",
"systemctl reload gunicorn"
]

**Full deploy pipeline — Docker Compose:**
exec_multi: host= commands=[
"cd /opt/myapp && git pull origin main",
"docker compose pull",
"docker compose up -d --remove-orphans --no-build"
]

**Full deploy pipeline — Go binary:**
exec_multi: host= commands=[
"cd /opt/myapp && git pull origin main",
"go build -o bin/app ./cmd/server",
"systemctl restart myapp"
]

**Health check after deploy:**
exec_command: host= cmd="curl -sf http://localhost:8080/health && echo OK || echo FAIL"

**Advanced health check with retry (3 attempts, 5s apart):**
exec_command: host= cmd="for i in 1 2 3; do curl -sf http://localhost:8080/health && echo OK && exit 0; sleep 5; done; echo FAIL; exit 1"

**Automatic rollback on failure:**
exec_multi: host= commands=[
"cd /opt/myapp && git reset --hard ",
"npm ci --production",
"systemctl restart myapp"
]

**Check deploy diff (what changed):**
exec_command: host= cmd="cd /opt/myapp && git log --oneline ..HEAD"

**Check service logs post‑deploy:**
exec_command: host= cmd="journalctl -u myapp -n 50 --no-pager"

**Blue‑green swap (via symlink):**
exec_multi: host= commands=[
"ln -sfn /opt/myapp-v2 /opt/myapp-current",
"systemctl reload nginx"
]

## Rollback Decision Logic
1. Run health check immediately after service restart  
2. If health check fails after 3 retries → execute rollback automatically  
3. If rollback also fails → alert and leave service in maintenance mode  
4. Always report: previous commit, deployed commit, rollback commit, total duration

## Output Format
- **Host**: name + app path  
- **Deploy status**: SUCCESS / FAILED / ROLLED BACK  
- **Commit deployed**: hash + message + author  
- **Previous commit**: hash (rollback reference)  
- **Duration**: total deploy time in seconds  
- **Health check**: endpoint + response code + latency  
- **Actions taken**: each pipeline step with exit code  
- **Recommendations**: DB migration warnings, cache flush, CDN invalidation

description: "Monitor and operate MySQL/MariaDB via SSH – processlist, replica status, slow log analysis, flush, table checks, backup verification" 
version: "1.0" 
tags: [mysql, mariadb, database, ops, replication, sql] 
host_required: true 
memory_scope: session+global 
project_required: false 
---

## Purpose
Monitor and operate MySQL/MariaDB instances via SSH. Inspect the processlist for long‑running queries, check replication health and lag, analyse the slow query log, flush tables/logs, verify InnoDB buffer pool usage, manage user connections, and confirm backup recency.

## Workflow
1️⃣ Identify target host from request  
2️⃣ Call `get_system_info` to confirm MySQL/MariaDB version  
3️⃣ Execute mysql CLI or mysqladmin commands via SSH  
4️⃣ Parse output & return a structured health report  
5️⃣ Suggest or apply corrective actions (never DROP without explicit confirmation)

## Available MCP Tools (SSH)

| Method | Parameters | Description |
|--------|-----------|-------------|
| `exec_command` | `host`, `cmd`, `timeout?` | Run mysql/mysqladmin shell commands |
| `exec_multi` | `host`, `commands[]` | Run multiple commands sequentially |
| `check_service` | `host`, `service` | Check mysql/mariadb systemctl status |
| `restart_service` | `host`, `service` | Restart MySQL service (use with caution) |
| `get_system_info` | `host` | Confirm OS & MySQL version |
| `download_file` | `host`, `remote_path`, `local_path` | Retrieve slow query logs or dumps |

## Instructions

**Service status & uptime**
exec_command: host=<name> cmd="systemctl status mysql --no-pager" exec_command: host=<name> cmd="mysqladmin -u root status"

**Full processlist (all connections)**
exec_command: host=<name> cmd="mysql -u root -e 'SHOW FULL PROCESSLIST\G' 2>/dev/null | head -100"

**Kill a long‑running query**
exec_command: host=<name> cmd="mysql -u root -e 'KILL QUERY <thread_id>;'"

**Replica status**
exec_command: host=<name> cmd="mysql -u root -e 'SHOW REPLICA STATUS\G'"

**Check replication lag (Seconds_Behind_Source)**
exec_command: host=<name> cmd="mysql -u root -e 'SHOW REPLICA STATUS\G' | grep Seconds_Behind"

**Enable / inspect slow query log**
exec_command: host=<name> cmd="mysql -u root -e 'SHOW VARIABLES LIKE "%slow%";'" exec_command: host=<name> cmd="tail -n 100 /var/log/mysql/mysql-slow.log"

**Top slow queries summary (mysqldumpslow)**
exec_command: host=<name> cmd="mysqldumpslow -s t -t 10 /var/log/mysql/mysql-slow.log"

**InnoDB buffer pool usage**
exec_command: host=<name> cmd="mysql -u root -e 'SHOW STATUS LIKE "Innodb_buffer_pool%";'"

**Table sizes (top 10)**
exec_command: host=<name> cmd="mysql -u root information_schema -e 'SELECT table_schema, table_name, ROUND(((data_length + index_length) / 1024 / 1024), 2) AS size_mb FROM tables ORDER BY size_mb DESC LIMIT 10;'"

**Flush slow logs & binary logs**
exec_multi: host=<name> commands=[ "mysql -u root -e 'FLUSH SLOW LOGS;'", "mysql -u root -e 'FLUSH BINARY LOGS;'" ]

## Safety Rules
- Never execute `DROP DATABASE`, `DROP TABLE` or `DELETE` without explicit user confirmation.  
- Always confirm the target schema before any write operation.  
- For `FLUSH TABLES WITH READ LOCK`, warn about global lock impact.

## Output Format
- **Host**: name + MySQL/MariaDB version  
- **Status**: OK / WARNING / CRITICAL  
- **Service**: running state + thread count + uptime  
- **Replication**: Seconds_Behind_Source per replica, IO/SQL thread state  
- **Slow queries**: top 5 with execution time  
- **Connections**: active vs max_connections  
- **Actions taken**: SQL commands executed with results  
- **Recommendations**: index optimisation, buffer pool sizing, replica catch‑up steps

host_required: true 
memory_scope: session+global 
project_required: false 
---

## Objective
Diagnose and remediate Linux system incidents over SSH.  
From a simple “the server is slow” complaint to a full post‑incident report, the agent gathers baseline metrics, runs targeted diagnostics (CPU, memory, disk, network, systemd), correlates findings, and returns a structured incident summary with severity, root cause, evidence, actions taken and follow‑up recommendations.

## Workflow
1. Identify target host from user request.  
2. Capture baseline snapshot (`get_system_info`).  
3. Execute diagnostic commands based on the reported symptom.  
4. Correlate CPU / memory / disk / network / logs.  
5. Return a structured incident report.
