Which MCP Server Should You Choose?
P
Choose PeppolStatus when:
You need dedicated capabilities in the Monitoring domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Peppol market intelligence and network monitoring: migrations, provider churn, leads, and uptime.
Transparent proxy for any MCP server that intercepts all JSON-RPC messages, measures latency, and stores traces in SQLite, PostgreSQL, or MySQL. Exports OpenTelemetry (OTLP) spans to Jaeger, Tempo, or Grafana. Supports stdio, HTTP, and SSE transports. npx @cardor/heimdall-mcp
List monitored hosts
Every monitored host with its current verdict, latest hourly all-locations latency and 24h uptime, worst-first, plus a network-wide rollup.
get_host
Get a host's current state
Current role, verdict, network attribution (IPs/PTR), TLS certificate and operating provider for a host. `?at=` returns point-in-time state.
list_host_incidents
List a host's incidents
Incidents for one host, newest-first, cursor-paginated.
get_host_uptime
Get a host's uptime aggregates
The aggregate ladder for a host at a chosen resolution, per-location plus the `__all__` rollup, optionally windowed by `[from, to)`, cursor-paginated.
list_host_software
List all hosts' software (Market)
Every host with open software fingerprint rows, one row per (hostname, role) with the vendor / version / hosting axes folded in (value, tier, first-seen; plus vendor `variant` and version `kind`). The evidence blob is omitted to keep the list lean — it stays on the per-host resource. Cursor-paginated on the stable (hostname, role) order; optional `vendor=` filter. Market tier.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
PeppolStatus is categorized under Monitoring and uses a remote streaming HTTP/SSE transport. In contrast, Heimdall MCP belongs to Monitoring using local stdio subprocess. Select PeppolStatus when you need capabilities focused on monitoring and Heimdall MCP when you require tools for monitoring.
Get a host's software fingerprint
The detected software of a host across ALL its roles: vendor, version and hosting per role, each with its confidence tier, first-seen timestamp and the structured evidence that fired. `?at=` returns point-in-time state. Market tier.
list_host_software_history
List a host's software-fingerprint history
The closed (superseded) software rows for one host, newest-first, cursor-paginated. Each row is one axis transition with its evidence. Market tier.
list_incidents
List incidents
The global incident feed, newest-first, cursor-paginated.
get_participant
Get a participant's current state
Directory presence, SML registration + current SMP, business card, the company-register enrichment block, endpoints and serving seats for a Peppol participant. Discovered participants carry no card; unmatched participants carry company: null.
list_participant_events
List a participant's change events
The participant's typed change events, newest-first, cursor-paginated.
get_participant_history
List a participant's temporal history
The participant's temporal rows across the directory/card/registration/SMP fact families, newest-first, cursor-paginated.
get_participant_availability
Get a participant's measured availability
The real, probe-measured reachability of one Peppol ID over time. Two lanes — the participant's SMP host (discovery) and its Access Point host(s) (delivery) — are read from the uptime ladder and merged per bucket into one verdict (available | degraded | unreachable | no_data): an AP with any down check is unreachable; an AP up/degraded with the SMP down is degraded (discovery impaired, still deliverable); both lanes up is available. Returns per-lane `UptimeBucket` ladders, the worst-of combined lane, 30/90-day + full headline uptime (degraded counts as available), a monthly 99.5% Peppol AP service-level TARGET (never a contractual claim), host-change markers and window-overlapping incidents. `daily` spans the full history; `hourly` covers the last 90 days. Buckets before the 2026-08-02 AP epoch carry partial AP attribution (`pre_epoch`).

Heimdall MCP Tools (14)
read_file
Read the complete contents of a file as text. DEPRECATED: Use read_text_file instead.
read_text_file
Read the complete contents of a file from the file system as text. Handles various text encodings and provides detailed error messages if the file cannot be read. Use this tool when you need to examine the contents of a single file. Use the 'head' parameter to read only the first N lines of a file, or the 'tail' parameter to read only the last N lines of a file. Operates on the file as text regardless of extension. Only works within allowed directories.
read_media_file
Read a file and return it as a base64-encoded content block with its MIME type. Image and audio files are returned as image/audio content; any other file type is returned as an embedded resource. Only works within allowed directories.
read_multiple_files
Read the contents of multiple files simultaneously. This is more efficient than reading files one by one when you need to analyze or compare multiple files. Each file's content is returned with its path as a reference. Failed reads for individual files won't stop the entire operation. Only works within allowed directories.
write_file
Create a new file or completely overwrite an existing file with new content. Use with caution as it will overwrite existing files without warning. Handles text content with proper encoding. Only works within allowed directories.
edit_file
Make line-based edits to a text file. Each edit replaces exact line sequences with new content. Returns a git-style diff showing the changes made. Only works within allowed directories.
create_directory
Create a new directory or ensure a directory exists. Can create multiple nested directories in one operation. If the directory already exists, this operation will succeed silently. Perfect for setting up directory structures for projects or ensuring required paths exist. Only works within allowed directories.
list_directory
Get a detailed listing of all files and directories in a specified path. Results clearly distinguish between files and directories with [FILE] and [DIR] prefixes. This tool is essential for understanding directory structure and finding specific files within a directory. Only works within allowed directories.
list_directory_with_sizes
Get a detailed listing of all files and directories in a specified path, including sizes. Results clearly distinguish between files and directories with [FILE] and [DIR] prefixes. This tool is useful for understanding directory structure and finding specific files within a directory. Only works within allowed directories.
directory_tree
Get a recursive tree view of files and directories as a JSON structure. Each entry includes 'name', 'type' (file/directory), and 'children' for directories. Files have no children array, while directories always have a children array (which may be empty). The output is formatted with 2-space indentation for readability. Only works within allowed directories.
move_file
Move or rename files and directories. Can move files between directories and rename them in a single operation. If the destination exists, the operation will fail. Works across different directories and can be used for simple renaming within the same directory. Both source and destination must be within allowed directories.
search_files
Recursively search for files and directories matching a pattern. The patterns should be glob-style patterns that match paths relative to the working directory. Use pattern like '*.ext' to match files in current directory, and '**/*.ext' to match files in all subdirectories. Returns full paths to all matching items. Great for finding files when you don't know their exact location. Only searches within allowed directories.
