Recheck needed

The source snapshot needs another refresh before maintenance can be interpreted.

No independently comparable adoption metric is currently stored.

Best for

Telnyx users who want an MCP client to call supported Telnyx API actions and can scope a dedicated API key.

Not ideal for

Users who need a broadly proven, low-risk, fully mature Selected-grade integration today.

Avoid if

Avoid high-impact or sensitive production use unless the documented authentication, permissions, rollback, and data handling match your environment.

Trade-offs

Communications/account actions require stronger least-privilege and operational-safety evidence before Selected.

Evidence-backed setup

Install & Agents

Choose your MCP client. A client connects to the MCP server; the language model is selected inside that client. Only stored, source-backed configurations are shown.

Claude Code

Transport not recorded

Publisher documented

Hosted: register `https://api.telnyx.com/v2/mcp` with `Authorization: Bearer <TELNYX_API_KEY>`; local alternative: `npx -y @telnyx/mcp --api-key=YOUR_TELNYX_API_KEY`.

The publisher provides client-specific setup instructions.

Verify safely: Claude Code: `claude mcp list` and/or `/mcp` to confirm Connected; use any stronger vendor-documented smoke test where listed.

Uninstall and revoke

Claude Code: `claude mcp remove <name>`; also revoke OAuth/device/API credentials in the vendor account when the vendor provides such a control.

Evidence & methodology

Publisher-documented setup is not the same as MCP100 execution testing. “MCP100 logic checked” means the stored configuration shape was reviewed, not that third-party MCP software was run.

Reviewed access

Access & risk

Review the exact access boundary before connecting this MCP to accounts, credentials, or sensitive data.

Authentication: Bearer Telnyx API key.
Permissions: Authority follows the exact Telnyx API key/account permissions; supported MCP actions may have real communications or account side effects.
Data handling: Requests and Telnyx account/API data transit the hosted Telnyx MCP and connected AI client.
Cost: Underlying Telnyx API/communications usage is billable according to the Telnyx account.
Risk and cautions: Communications/account actions require stronger least-privilege and operational-safety evidence before Selected.

Telnyx Remote Model Context Protocol (MCP)

Remote endpoint

The canonical Telnyx API MCP endpoint is https://api.telnyx.com/v2/mcp. Use this endpoint for MCP clients or scanners that need Telnyx API actions. It uses streamable HTTP and Bearer authentication with Authorization: Bearer <TELNYX_API_KEY>.The API action server card describes this API endpoint. Inspect the selected endpoint schema and obtain authorization before invoking billable or state-changing actions.For documentation search and retrieval, use https://developers.telnyx.com/mcp. Its documentation server card describes a separate, documentation-focused service. It is not a mirror of the API action server card. Documentation search and retrieval are read-only, but the submit_feedback tool writes documentation feedback. Documentation retrieval does not execute Telnyx API actions; connect to https://api.telnyx.com/v2/mcp for those actions.
