Tool reference
Every tool the server exposes, grouped by what it does.
How it works
- Transport: Streamable HTTP (the current MCP standard). The server is stateless, so there are no sessions to manage and any request can hit any node.
- Authentication: your Bland API key in the
Authorizationheader (Bearer org_...). The key’s organization scopes every tool: an agent connected with your key sees only your org’s calls, pathways, and agents. Get a key from the dashboard. - Rate limits: 120 requests per minute per organization.
- Safety: every tool is annotated read-only or destructive, so well-behaved clients ask before the agent does anything with side effects (like placing a real phone call). Mutating tools additionally require an explicit confirmation argument.
What your agent can do
See the full tool reference.
The server also ships MCP prompts:
build_pathway and edit_pathway appear as slash commands in clients that support them (like Claude Code) and load Bland’s pathway-authoring doctrine into the session.
One endpoint, three MCP surfaces
Bland has three MCP-related surfaces. If you’re unsure, use the first one.Security notes
- Treat your API key like a password. Use environment variables or your client’s secret storage. Never commit it to a repo.
- Tools that spend money or touch live traffic (placing calls, publishing agents) are marked destructive and confirmation-gated, but review what your agent proposes before approving.
- MCP tool results can contain untrusted content (e.g. call transcripts of real conversations). Prompt-injection-aware clients like Claude Code treat tool output as data, but keep it in mind when building your own agent loops.
