MCP Context Provider

Persistent context and learned instincts for Claude Desktop and Claude Code — surviving across sessions.

A TypeScript MCP server that gives Claude persistent Contexts (static tool rules) and Instincts (learned, confidence-scored rules distilled from sessions). No more re-establishing context in every new chat.

Architecture

Two core concepts:

Concept	Description	Size	Lifetime
Context	Static tool rules, syntax preferences, auto-corrections	200–1000 tokens	Permanent, manually authored
Instinct	Learned rule extracted from sessions, confidence-scored	20–80 tokens	Human-approved, evolves over time

Four subsystems:

• Engine — loads, matches, and merges contexts + instincts into injection payloads
• MCP Server (src/server/index.ts) — stdio + HTTP transport, 6 MCP tools
• CLI (mcp-cp) — approval registry for instinct lifecycle management
• Memory Bridge — optional sync of instincts to mcp-memory-service

Quick Start

git clone https://github.com/doobidoo/MCP-Context-Provider.git
cd MCP-Context-Provider
npm install
npm run build

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "context-provider": {
      "command": "node",
      "args": ["/path/to/mcp-context-provider/dist/server/index.js"],
      "env": {
        "CONTEXTS_PATH": "/path/to/mcp-context-provider/contexts",
        "INSTINCTS_PATH": "/path/to/mcp-context-provider/instincts"
      }
    }
  }
}

Claude Code (global)

Add to ~/.mcp.json:

{
  "mcpServers": {
    "context-provider": {
      "command": "node",
      "args": ["/path/to/mcp-context-provider/dist/server/index.js"],
      "env": {
        "CONTEXTS_PATH": "/path/to/mcp-context-provider/contexts",
        "INSTINCTS_PATH": "/path/to/mcp-context-provider/instincts"
      }
    }
  }
}

Important: Use absolute paths for both args and env values. Claude Code does not support the cwd field in MCP server configs — relative paths will resolve from the wrong directory and the server will fail to connect.

Claude Code Plugin (Marketplace)

Install directly from the marketplace:

/plugin marketplace add doobidoo/MCP-Context-Provider
/plugin install context-provider

This auto-configures the MCP server with correct paths — no manual .mcp.json editing needed.

/instill Skill (Claude Code)

Install the skill globally (stays current with git pull):

mkdir -p ~/.claude/skills/instill
ln -s /path/to/mcp-context-provider/.claude/skills/instill.md ~/.claude/skills/instill/SKILL.md

Then use /instill at the end of productive sessions to distill learned patterns into instinct candidates.

Auto-Trigger Hook (Optional)

The instill-trigger hook automatically detects mistakes during a session and nudges Claude to suggest /instill when a threshold is reached. It monitors:

• User corrections (UserPromptSubmit) — "no not that", "that's wrong", "still broken", etc.
• Tool failures (PostToolUse) — non-zero exit codes, tracebacks, permission errors

Install the hook:

cp hooks/instill-trigger.js ~/.claude/hooks/core/instill-trigger.js

Register in ~/.claude/settings.json under both UserPromptSubmit and PostToolUse:

{
  "type": "command",
  "command": "node --no-warnings \"~/.claude/hooks/core/instill-trigger.js\"",
  "timeout": 3
}

Scoring: Corrections weighted 1.5x, tool failures 0.5x. Combined threshold: 3.0. Max 1 nudge per session. All tunable via CONFIG object in the hook file.

MCP Tools

Tool	Description
get_tool_context	Get complete context for a tool category
get_syntax_rules	Get syntax-specific rules for a tool
list_available_contexts	List all loaded contexts
apply_auto_corrections	Apply correction patterns to text
build_injection	Combined context + instinct injection payload
list_instincts	List all instincts with confidence scores

Environment Variables

Variable	Default	Description
CONTEXTS_PATH	./contexts	Path to *_context.json files
INSTINCTS_PATH	./instincts	Path to *.instincts.yaml files
MEMORY_BRIDGE_URL	—	Memory service base URL (enables bridge)
MEMORY_BRIDGE_API_KEY	—	API key for memory service
MCP_SERVER_PORT	3100	HTTP server port (only with --http)

Context Files

Contexts are JSON files in contexts/*_context.json. Each file matches one or more tools via glob patterns and injects static rules.
