Claude Chat MCP

Connect Claude Desktop to the self-hosted / enterprise tools your office actually uses.

Anthropic's official connectors mostly cover the public cloud editions of tools (Confluence Cloud, etc.). But corporate users live in the self-hosted / Data Center / on-prem editions their company runs behind a firewall — and in tools Claude doesn't support at all. This project is a growing collection of local MCP connectors that fill exactly that gap.

Each connector is a small, self-contained MCP server that Claude Desktop launches over stdio. No cloud, no hosting, works behind corporate proxies.

Open-source (MIT). Cross-platform target: Windows, macOS, Linux. Windows ships as a proper installer (planned — see Roadmap).

Connectors

Each tool/service is its own standalone connector (its own binary and process):

¹ Oracle is gated behind the oracle build feature and requires Oracle Instant Client (it has no pure-Rust driver). The others are fully self-contained.

Run any connector with --manifest to see its config fields; registry.json aggregates all of them, and scripts/serve-site.ps1 serves a bilingual (EN/VI) catalog site at http://localhost:4321.

Build (local, for review)

Requires the Rust toolchain (stable) and, on Windows, Visual Studio Build Tools with the C++ workload + Windows SDK (the MSVC linker). The repo's wrapper loads the MSVC dev environment for you:

./scripts/cargo.ps1 build            # debug build of all connectors
./scripts/cargo.ps1 test             # run the test suite

On macOS/Linux you can use cargo directly (no wrapper needed).

Binaries land in target/debug/{atlassian,airtable,database}.exe.

Try it in Claude Desktop

Until the GUI configurator ships, register a built connector with your local Claude Desktop:

# Confluence (self-hosted)
./scripts/install-local.ps1 confluence @{ CONFLUENCE_URL="https://wiki.corp.com"; CONFLUENCE_TOKEN="<your PAT>" }

# MySQL (read-only)
./scripts/install-local.ps1 mysql @{ DB_HOST="127.0.0.1"; DB_USER="root"; DB_PASSWORD="secret"; DB_NAME="app" }

# Airtable
./scripts/install-local.ps1 airtable @{ AIRTABLE_TOKEN="<your PAT>" }

For non-technical users, the GUI installer (roadmap) replaces these commands with a click-through wizard. The scripts/ path is the developer/reviewer route.

Then fully quit Claude Desktop (tray → Exit) and reopen it. Ask Claude things like "Search our Confluence for the deployment runbook" or "List the tables in the app database."

To do it by hand instead, add an entry to claude_desktop_config.json → mcpServers with command = the binary path and env = the connector's variables.

Architecture

See ARCHITECTURE.md. In short: a shared connector-core (HTTP client, auth, proxy/PAC, retry) and server-runtime (stdio MCP host), with one small server binary per connector. Adding a connector means adding one crate — see CONTRIBUTING.md.

Roadmap

• GUI configurator (Tauri) — manifest-driven, multi-connector, writes the Claude Desktop config; Windows installer (MSI/NSIS), macOS .pkg/.dmg, Linux .deb/.AppImage.

• More connectors (GitLab self-hosted, ServiceNow, internal APIs, …).

• Companion website / SEO content hub generated from registry.json.
