Who it is for
A construction project manager or superintendent whose decisions get made on phone calls that nobody writes down.
Searchable records from jobsite calls and site notes
Overview
Hardline captures phone calls and site conversations from construction work and turns them into searchable records. The transcript is kept; the audio is not.
Search runs across those records by project, by person, by trade, or by date range, and answers cite the specific call the information came from. The record lists several jobsite uses. A daily log can be assembled from the day's calls rather than reconstructed from memory. Change orders and RFIs can be drafted with the field context attached, covering what the architect approved and what a subcontractor flagged. Disputes over who committed to what resolve against a contemporaneous record. Look-ahead scheduling and owner-architect-contractor meetings can draw on the week's calls alongside other project documents.

Answers point back at the specific call they came from, so a commitment can be traced rather than argued about.
Availability
Hardline AI Corp. ships this on both marketplaces: Hardline is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain.
Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process.
ChatGPT listing
Claude listing
Hardline publishes 22 tools to Claude, deeper than 72.2% of the 1,253 Claude-listed connectors.
The median Claude-listed connector filed under Productivity publishes 12, so this one runs 10 tools above its bucket's median and ranks 133rd of 462 by tool count.
It falls in the 21-50 tools band, which holds 20% of the Claude directory.
Hardline publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.
https://api.hardlineapp.com/mcp Hardline is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
In the publisher's words
Hardline MCP connects your notes from your phone calls and site meetings to Claude. Use this MCP when you are looking to connect real time data from the jobsite into your tools and workflows. - Writing a daily log: Pull the decisions, commitments, and delivery updates from today's calls straight into the log, instead of backfilling from memory hours later. - Drafting an RFI or change order: Pull the field context behind it. What the architect approved, what the sub flagged, what changed on the call, all in the draft. - Settling a "you told me to" dispute: Find who committed to what and when, with the exact call it came from. The contemporaneous record, on demand. Hardline helps you connect valuable information and photos to the rest of your system.

This is an independent catalogue entry compiled by Node8 from Hardline's public marketplace listings as they stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Hardline AI Corp., and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
