veyra-snippets

A persistent code snippet manager MCP tool for AI agents, with language filtering, tag search, and full-text code search. Reads are always free. Write operations require Veyra commit mode authorization.

Overview

veyra-snippets gives AI agents a reliable code library backed by SQLite. Agents can freely browse and search snippets. Saving, updating, and deleting snippets is protected by Veyra commit mode — ensuring intentional, accountable writes.

Installation

npm install
npm run build

Snippets are stored at ~/.veyra-snippets/data.db, created automatically on first run.

Examples

Read (no token needed)

// List all snippets
{ "tool": "list_snippets", "arguments": {} }

// List TypeScript snippets
{ "tool": "list_snippets", "arguments": { "language": "typescript" } }

// List snippets by tag
{ "tool": "list_snippets", "arguments": { "tag": "auth" } }

// Get a specific snippet
{ "tool": "get_snippet", "arguments": { "id": "1712345678-abc1234" } }

// Search across title, code, language, and tags
{ "tool": "search_snippets", "arguments": { "query": "debounce" } }

Write (Veyra token required)

// Save a new snippet
{
  "tool": "save_snippet",
  "arguments": {
    "title": "Debounce utility",
    "code": "function debounce(fn, ms) {\n  let timer;\n  return (...args) => {\n    clearTimeout(timer);\n    timer = setTimeout(() => fn(...args), ms);\n  };\n}",
    "language": "javascript",
    "tags": "utility,performance",
    "veyra_token": "vt_..."
  }
}

// Update snippet code
{
  "tool": "update_snippet",
  "arguments": {
    "id": "1712345678-abc1234",
    "code": "// updated code here",
    "veyra_token": "vt_..."
  }
}

// Delete a snippet
{
  "tool": "delete_snippet",
  "arguments": {
    "id": "1712345678-abc1234",
    "veyra_token": "vt_..."
  }
}

Error response when token is missing

{
  "error": "VeyraCommitRequired",
  "message": "Write operations require Veyra commit mode.",
  "currentMode": "open",
  "requiredMode": "commit",
  "transitionStrategy": "authorize_then_retry_with_x_veyra_token",
  "provider": "veyra",
  "authorize_endpoint": "https://api.veyra.to/v1/authorize-action",
  "docs_url": "https://veyra.to"
}

How Veyra Works

Veyra is a commit-mode authorization layer for AI agents. When an agent attempts a write operation:

  1. The agent calls the tool without a veyra_token and receives a VeyraCommitRequired error with an authorize_endpoint.

  2. The agent (or the user on its behalf) calls the authorize endpoint to obtain a token.

  3. The agent retries the tool call with veyra_token set.

  4. veyra-snippets verifies the token via @veyrahq/sdk-node before executing the write.

See veyra.to for full documentation.
