## Advanced Configuration Tables

Advanced operational tables in `niki.toml`.

---

## `[goal]` Table

Autonomous multi-step goal execution:

```toml
[goal]
max_iterations = 25
branch_prefix  = "niki-goal/"
state_dir      = ".niki/goals"
fail_fast      = false
retry_attempts = 3
retry_delay_ms = 1000
```

---

## `[mcp]` Table

Integrate external Model Context Protocol tool servers into NIKI agents:

```toml
[mcp]
enabled    = true
timeout_ms = 30000

[[mcp.servers]]
name    = "github"
command = "npx"
args    = ["-y", "@modelcontextprotocol/server-github"]
env     = { GITHUB_PERSONAL_ACCESS_TOKEN = "ghp_..." }
```

## `[ui]`, `[session]`, and `[compaction]`

```toml
[ui]
theme      = "auto" # "auto" | "dark" | "light"
tips       = true
transcript = true

[session]
enabled      = true
max_sessions = 50
auto_save    = true

[compaction]
enabled         = true
threshold_pct   = 85 # Trigger compaction when 85% of model context is filled
reserved_tokens = 4096
```
