mcp-servers

Pilot MCP Servers

MCP tools are lazy-loaded via ToolSearch. Discover tools by keyword, then call them directly.

ToolSearch(query="keyword")        # Discover and load tools by keyword
ToolSearch(query="+server keyword") # Require a specific server prefix
ToolSearch(query="select:full_tool_name") # Load a specific tool by exact name

All Pilot MCP servers use the mcp__plugin_pilot_ prefix. Tools are available immediately after ToolSearch returns them.

mem-search — Persistent Memory

Purpose: Search past work, decisions, and context across sessions.

3-step workflow (token-efficient — never skip to step 3):

Types: bugfix, feature, refactor, discovery, decision, change

# Discover tools
ToolSearch(query="+mem-search search")

# Then call directly
mcp__plugin_pilot_mem-search__search(query="authentication flow", limit=5)
mcp__plugin_pilot_mem-search__timeline(anchor=22865, depth_before=3, depth_after=3)
mcp__plugin_pilot_mem-search__get_observations(ids=[22865, 22866])
mcp__plugin_pilot_mem-search__save_memory(text="Important finding", title="Short title")

context7 — Library Documentation

Purpose: Fetch up-to-date docs and code examples for any library/framework.

2-step workflow:

ToolSearch(query="+context7 resolve")

mcp__plugin_pilot_context7__resolve-library-id(query="how to use fixtures", libraryName="pytest")
# → returns libraryId like "/pypi/pytest"
mcp__plugin_pilot_context7__query-docs(libraryId="/pypi/pytest", query="how to create and use fixtures")

Use descriptive queries. Max 3 calls per question per tool.

web-search — Web Search

Purpose: Search the web via DuckDuckGo, Bing, or Exa (no API keys needed).

ToolSearch(query="+web-search search")

mcp__plugin_pilot_web-search__search(query="Python asyncio best practices 2026", limit=5)
mcp__plugin_pilot_web-search__fetchGithubReadme(url="https://github.com/astral-sh/ruff")

grep-mcp — GitHub Code Search

Purpose: Find real-world code examples from 1M+ public repositories.

Single tool: searchGitHub

ToolSearch(query="+grep-mcp searchGitHub")

mcp__plugin_pilot_grep-mcp__searchGitHub(query="FastMCP", language=["Python"])
mcp__plugin_pilot_grep-mcp__searchGitHub(query="(?s)useEffect\\(.*cleanup", useRegexp=True, language=["TypeScript"])

web-fetch — Web Page Fetching

Purpose: Fetch full web pages via Playwright (no truncation, handles JS-rendered pages).

ToolSearch(query="+web-fetch fetch")

mcp__plugin_pilot_web-fetch__fetch_url(url="https://docs.example.com/api")
mcp__plugin_pilot_web-fetch__fetch_urls(urls=["https://a.com", "https://b.com"])

Options: waitUntil (load/domcontentloaded/networkidle), returnHtml, waitForNavigation (for anti-bot pages).

codebase-memory-mcp — Code Knowledge Graph

Purpose: Structural code analysis, call tracing, dead code detection, and impact analysis via a persistent code graph.

Complements Probe CLI: Probe finds code by intent ("how does auth work?"). codebase-memory finds by structure ("who calls this?", "what's dead?", "what's the blast radius?").

Key tools:

Workflow: Check index_status → index_repository if needed → search_graph / trace_call_path / query_graph

ToolSearch(query="+codebase-memory-mcp search")

mcp__plugin_pilot_codebase-memory-mcp__search_graph(label="Function", name_pattern=".*Handler.*")
mcp__plugin_pilot_codebase-memory-mcp__trace_call_path(function_name="ProcessOrder", direction="both", depth=2)
mcp__plugin_pilot_codebase-memory-mcp__detect_changes(scope="all")
mcp__plugin_pilot_codebase-memory-mcp__get_code_snippet(qualified_name="MyClass", auto_resolve=true, include_neighbors=true)

When to use over Probe:

• Call tracing / impact analysis (Probe can't do this)
• Dead code detection (max_degree=0, exclude_entry_points=true)
• Structural queries via Cypher (class methods, interface implementations)
• Change blast radius analysis
• Code snippets with caller/callee context

When Probe is better:

• Intent-based search ("how does authentication work?")
• Natural language queries
• AST-aware code extraction by line/symbol
