* fix: n8n_test_workflow webhookId resolution and form handling (v2.28.2)
## Bug Fixes
- **webhookId Resolution**: Fixed trigger handlers using `node.id` instead of
`node.webhookId` for building webhook URLs. This caused 404 errors when
nodes had custom IDs.
- **Chat Trigger URL**: Fixed chat triggers using wrong URL pattern. Now
correctly uses `/webhook/<webhookId>/chat` endpoint.
- **Form Content-Type**: Fixed form triggers failing with "Expected
multipart/form-data" error by switching to proper multipart encoding.
## Enhancements
- **Form Field Types**: Added support for all n8n form field types (text,
textarea, email, number, password, date, dropdown, checkbox, file, hidden)
- **Checkbox Arrays**: Automatically converts arrays to `field[]` format
- **Helpful Warnings**: Reports missing required fields with names and labels
- **Error Hints**: Provides complete field structure on failure

* fix: prevent workflow validator from mutating node types
The validator was incorrectly mutating node types from full form
(n8n-nodes-base.*) to short form (nodes-base.*) during validation.
This caused deployed workflows to show "?" icons in n8n UI because
the API requires full form node types.
Also updated SplitInBatches detection to check both node type forms
since workflows may contain either format.

* fix: pin MCP SDK and Zod versions to prevent Zod v4 resolution
Fixes#440, #444, #446, #447, #450
Root cause: package.json declared `"@modelcontextprotocol/sdk": "^1.20.1"`
which allowed npm to resolve to SDK 1.23.0. That version accepts
`"zod": "^3.25 || ^4.0"`, causing npm to deduplicate to Zod v4.
SDK 1.23.0's `isZ4Schema()` function crashes when called with undefined,
which happens for plain JSON Schema objects.
Changes:
- Pin SDK to exact version 1.20.1 (removes ^ prefix)
- Pin Zod to exact version 3.24.1 (removes ^ prefix)
- Add CI workflow to verify fresh installs get compatible versions
The new CI workflow:
- Packs and installs package fresh (without lockfile)
- Verifies SDK is exactly 1.20.1
- Verifies Zod is NOT v4 (blocks 4.x.x)
- Runs weekly to catch upstream dependency changes

* fix: align FTS5 tests with production boosting logic
Tests were failing because they used raw FTS5 ranking instead of the
exact-match boosting logic that production uses. Updated both test files
to replicate production search behavior from src/mcp/server.ts.
- Updated node-fts5-search.test.ts to use production boosting
- Updated database-population.test.ts to use production boosting
- Both tests now use JOIN + CASE statement for exact-match prioritization
This makes tests more accurate and less brittle to FTS5 ranking changes.

* fix: prioritize exact matches in FTS5 search with case-insensitive comparison
Root cause: SQL ORDER BY was sorting by FTS5 rank first, then CASE statement.
Since ranks are unique, the CASE boosting never applied. Additionally, the
CASE statement used case-sensitive comparison which failed to match nodes
like "Webhook" when searching for "webhook".
Changes:
- Changed ORDER BY from "rank, CASE" to "CASE, rank" in production code
- Added LOWER() for case-insensitive exact match detection
- Updated both test files to match the corrected SQL logic
- Exact matches now consistently rank first regardless of FTS5 score
Impact:
- Improves search quality by ensuring exact matches appear first
- More efficient SQL (less JavaScript sorting needed)
- Tests now accurately validate production search behavior
- Fixes 2/705 failing integration tests
Verified:
- Both tests pass locally after fix
- SQL query tested with SQLite CLI showing webhook ranks 1st

Implements custom server icons for MCP clients according to the MCP

the n8n-mcp server in MCP client interfaces.
Features:
- Added 3 icon sizes: 192x192, 128x128, 48x48 (PNG format)
- Icons served from https://www.n8n-mcp.com/logo*.png
- Added websiteUrl field pointing to https://n8n-mcp.com
- Server version now uses package.json (PROJECT_VERSION) instead of hardcoded '1.0.0'
Changes:
- Upgraded @modelcontextprotocol/sdk from ^1.13.2 to ^1.20.1
- Updated src/mcp/server.ts with icon configuration
- Bumped version to 2.20.0
- Updated CHANGELOG.md with release notes
Testing:
- All icon URLs verified accessible (HTTP 200, CORS enabled)
- Build passes, type checking passes
- No breaking changes, fully backward compatible
Icons won't display in Claude Desktop yet (pending upstream UI support),

## Problem
PR #309 added `main`, `types`, and `exports` fields to package.json for library usage,
but v2.18.9 was published without these fields. The publish scripts (both local and CI/CD)
use package.runtime.json as the base and didn't copy these critical fields.
Result: npm package broke library usage for multi-tenant backends.
## Root Cause
Both scripts/publish-npm.sh and .github/workflows/release.yml:
- Copy package.runtime.json as base package.json
- Add metadata fields (name, bin, repository, etc.)
- Missing: main, types, exports fields
## Changes
### 1. scripts/publish-npm.sh
- Added main, types, exports fields to package.json generation
- Removed test suite execution (already runs in CI)
### 2. .github/workflows/release.yml
- Added main, types, exports fields to CI publish step
### 3. Version bump
- Bumped to v2.18.10 to republish with correct fields
## Verification
✅ Local publish preparation tested
✅ Generated package.json has all required fields:
- main: "dist/index.js"
- types: "dist/index.d.ts"
- exports: { "." : { types, require, import } }
✅ TypeScript compilation passes
✅ All library export paths validated
## Impact
- Fixes library usage for multi-tenant deployments
- Enables downstream n8n-mcp-backend project
- Maintains backward compatibility (CLI/Docker unchanged)

- Remove examples from get_node_essentials responses
- Remove examples from validate_node_operation when errors occur
- Update documentation to reflect removal of examples
- Keep helpful format hints in get_node_for_task (different purpose)
The auto-generated examples were misleading AI agents with incorrect
configurations (e.g., Slack "channel" vs "select" property). Tools
now focus on validation and error messages instead of examples.
