### Source README

#### paseo-mcp-tools plugin

Provides an inline UI for checking MCP servers available to an agent session with additional functionality per MCP, such as listing and directly executing MCP tools with auto-generated input forms. Uses the most authoritative list per provider CLI and verifies actual session inclusion with live probes.

(**Paseo** is an agent orchestrator: AI coding agents run on paseo daemons, each managing workspaces, tools, and permissions.)

Built on [paseo-plugin-helper](https://github.com/xpufx/paseo/tree/main/packages/paseo-plugin-helper), the shared Paseo plugin runtime.

##### What it does

- **Pill** above the composer shows `MCP n` (live servers for that agent). Badge updates via `mcp.list`, shared between pill and modal.
- **Live discovery** per-CLI via isolated `providers/<id>.ts` (`opencode` → `opencode mcp list`, `claude` → `~/.claude.json` live, `antigravity` → `~/.gemini/config/mcp_config.json`, etc.) + Paseo-injected `StoredAgentRecord.mcpServers`. Groups by `source.label`, dedupes by name.
- **Paseo Built-in Host MCP**: Automatically discovers Paseo's host daemon control plane (`/mcp/agents?callerAgentId=...`) as a first-class MCP server (`Paseo (Builtin)`), exposing all 60+ live tools (workspaces, browser automation, schedules, terminals, agent orchestration).
- **Detail & Live Health**: Server tap reveals real-time status dots, latency, server instructions, and full tool declarations.
- **Interactive Tool Runner (User Execution)**: Users can execute any discovered MCP tool directly from the UI without prompting the agent. Features a dynamic schema-driven form with `*REQUIRED` validation, type coercion (boolean, number, object, array, union/nullable types), live tool execution via host RPC (`mcp.call_tool`), and output inspection with 1-tap clipboard copying.
- **Real-Time Tool Search**: Server Detail view features a real-time search input filtering across tool names and descriptions, making servers with large command sets (like Paseo, Forgejo, Chrome DevTools) fast and easy to navigate.
- **Diagnostics**: Full polymorphic probe checklist verifying paths, permissions, and agent records across hosts.

##### Supported Providers

| Provider | Probe Mechanism | Status |
|---|---|---|
| **Paseo** (`paseo`) | Built-in host daemon MCP control plane (`~/.paseo/config.json` + live daemon HTTP session) | **Fully tested & verified (60+ tools)** |
| **Antigravity** (`antigravity`, `antigravity-acp`) | Global `~/.gemini/config/mcp_config.json` + `~/.antigravity/mcp_config.json` | **Fully tested & verified** |
| **OpenCode** (`opencode`) | Live `opencode mcp list` daemon CLI command + config | **Fully tested & verified** |
| **Pi** (`pi`) | User canonical `~/.pi/.mcp.json` / project overrides + heuristics | **Fully tested & verified** |
| **Claude** (`claude`) | User `~/.claude.json` / project `.claude.json` heuristics | **Tested against real active configs** *(without live subscription session)* |
| **CodeX** (`codex`) | Global `~/.codex/config.toml` / project `.codex/config.toml` | **Provided as-is** *(without guarantees)* |

##### Dropping in New Providers

Adding a new tool/CLI probe (e.g. Cursor, Windsurf, Zed, Roo, Cline) is black-box and takes 2 simple steps:
1. Create `providers/<id>.ts` declaring candidate config paths using `discoverFromCandidates()` (or live CLI RPC) with `export default <id>Probe`.
2. Add a 1-line re-export to `providers/catalog.ts`: `export { default as <id> } from "./<id>";`.

See the complete step-by-step guide in the [write-mcp-provider skill](.agents/skills/write-mcp-provider/SKILL.md) (`.agents/skills/write-mcp-provider/SKILL.md`). Run `npm test` to automatically verify the probe satisfies the contract.

##### Layout

| File | Owns |
|---|---|
| [`index.ts`](index.ts) | Wiring only: `handle(mcp.list)`, `handle(mcp.read)`, `handle(mcp.health)`, `handle(mcp.call_tool)`, `handle(mcp.diagnose)`, `addClientSide` |
| [`mcp.shared.ts`](mcp.shared.ts) | zod RPC contracts & shared types (`ToolInfoSchema`, `callMcpTool`, etc.) |
| [`mcp.server.ts`](mcp.server.ts) | `discoverLiveServers()`, tool runner execution bridge, and polymorphic diagnostic handlers |
| [`discovery/extract.ts`](discovery/extract.ts) | Universal heuristic MCP parser (JSON/JSONC, comments, trailing commas, URL safe) & candidate discovery |
| [`discovery/types.ts`](discovery/types.ts) | Core contracts (`McpProbe`, `ProbeContext`, `ProbeResult`) |
| [`providers/<id>.ts`](providers/) | Per-CLI live probe (isolated, contract `McpProbe`: `antigravity.ts`, `claude.ts`, etc.) |
| [`providers/paseo.ts`](providers/paseo.ts) | Dedicated host daemon probe discovering Paseo control plane & tools |
| [`providers/catalog.ts`](providers/catalog.ts) | 1-line re-export catalog for zero-boilerplate probe registration |
| [`health/health.server.ts`](health/health.server.ts) | Generic MCP SDK client (`instructions`, schema-aware `tools`, and `callMcpServerTool`) |
| [`mcp-query.client.tsx`](mcp-query.client.tsx) | `useMcpQuery` shared pill/modal, 30m timer + manual Refresh |
| [`pill.client.tsx`](pill.client.tsx) | Pill, modal, server details, diagnostics, real-time search, and interactive Tool Runner UI |
| [`scripts/version.mjs`](scripts/version.mjs) | Offline build-time version stamper (tag / beta-[hash]) |
| [`docs/TEST_METHODOLOGY.md`](docs/TEST_METHODOLOGY.md) | Test procedures, adapter verification, and QA methodology |

##### Install & Updates

```bash
# from git (recommended)
paseo plugin add xpufx/paseo-mcp-tools

# update to latest release
paseo plugin update mcp-tools

# or from a local checkout (path-linked for development)
paseo plugin install "$PWD"

# reload daemon process after local edits
paseo plugin reload mcp-tools
```

`pluginsEnabled: true` required. Use `paseo plugin logs mcp-tools` for diagnostics and runtime logs. Failed reload stays failed (Paseo doesn't restore).
