MCP server
The AI Agents framework exposes a Model Context Protocol (MCP) server so that MCP clients (such as Claude Desktop and Claude Code) can provision and troubleshoot voice AI applications — creating and editing agents, tools, documents and flows, chatting with agents to test them, inspecting past conversations, and reading this documentation.
The server is embedded in the management service and exposed over streamable HTTP at:
/ai-framework-management/api/v1/mcp/
Always connect with the trailing slash (.../api/v1/mcp/). The endpoint is served at the
trailing-slash path; a request to the slash-less URL is answered with an HTTP redirect, and some MCP
clients — notably the mcp-remote stdio bridge that Claude Desktop uses — don't follow that redirect
on a POST and fail to connect.
Connecting
Two MCP clients are supported today: Claude Code and Claude Desktop. Both connect to the same
endpoint using your LiveHub API client's client_id and client_secret: the server handles
authentication for you and keeps the short-lived token refreshed, so there is no token to manage. The
identity determines the account, and all operations are scoped to it. If you don't have these
credentials yet, see Getting your client_id and client_secret below.
Getting your client_id and client_secret
Your client_id and client_secret belong to a LiveHub API client, which you create — and grant
the Administrator role — from the Access control (IAM) screen:
-
Click your account name shown at the top of the screen.
-
In the account dialog, click Access control (IAM).
-
In the IAM screen, select API Clients in the left menu, then click Add API Client.
- Enter a name for the API client — for example,
claude. - Copy the generated Client Id and Client Secret. The Client Secret is shown only once, so save it now — it will not be visible again after you close the screen.
- Enter a name for the API client — for example,
-
Grant the new API client the Administrator role so it can provision and manage entities — select User groups in the left menu.
- Find the Administrator group in the list and click Edit.
-
Switch to the API Clients tab, click Add API Client, and select the API client you created above.
Use the Client Id as X-Client-Id and the Client Secret as X-Client-Secret in the connection
settings below.
Claude Code
Register the server with claude mcp add:
claude mcp add --transport http livehub-ai-agents https://livehub.audiocodes.io/ai-framework-management/api/v1/mcp/ \
--header "X-Client-Id: <id>" --header "X-Client-Secret: <secret>"
Claude Desktop
Claude Desktop connects to the streamable-HTTP endpoint through the
mcp-remote bridge. Add the following to your
claude_desktop_config.json (note the trailing slash on the URL — see the note above), then
restart Claude Desktop:
{
"mcpServers": {
"livehub-ai-agents": {
"command": "npx",
"args": [
"mcp-remote",
"https://livehub.audiocodes.io/ai-framework-management/api/v1/mcp/",
"--header", "X-Client-Id:<id>",
"--header", "X-Client-Secret:<secret>"
]
}
}
}
Clients that support only one custom header
Some MCP clients let you set only a single custom header. For those, pass both credentials in
one X-Client-Credentials header, as <client_id>:<client_secret> (client id, a colon, then
client secret).
Clients that use HTTP Basic authentication
For clients whose only authentication affordance is standard HTTP Basic auth, pass the
client_id as the username and the client_secret as the password. The client encodes
them into the standard Authorization: Basic <base64(client_id:client_secret)> header, which the
server accepts in place of the X-Client-* headers.
Providing your own access token
As an alternative to passing the X-Client-Id / X-Client-Secret headers, you can obtain a LiveHub
access token yourself (see Secured REST API)
and supply it as a standard Authorization: Bearer header instead:
claude mcp add --transport http livehub-ai-agents https://livehub.audiocodes.io/ai-framework-management/api/v1/mcp/ \
--header "Authorization: Bearer <access-token>"
A LiveHub access token is valid for one hour. Because you supply it once, at the start of the MCP
session, you must acquire a fresh token for every new session — and re-acquire it partway through a
long session, since the connection keeps sending the same token and calls start failing once it
expires. This is exactly why X-Client-Id / X-Client-Secret is preferred: the server re-acquires
and refreshes the token for you transparently.
Read-only mode
Append ?mode=read-only to the URL to restrict the connection to reading and troubleshooting:
https://livehub.audiocodes.io/ai-framework-management/api/v1/mcp/?mode=read-only
A read-only connection sees only the read, documentation, conversation-troubleshooting and chat tools;
the provisioning tools (apply, create_or_update_*, delete_entity) are hidden and any attempt to
call them is rejected. Reconnect without the parameter to make changes.
Core concepts
The platform builds voice AI applications as an orchestration layer over LLMs. Its entities are:
- Agent — an LLM-driven conversational agent (prompt, LLM, tools, documents, sub-agents). Multiple agents form multi-agent topologies.
- Tool — an operation an agent can call: either a custom tool (a REST call, an MCP server, or a
Flow) or a platform builtin (
end_call,transfer_call, …). An agent'stools_configreferences a builtin by name ({"tool": "end_call"}) and a custom tool as{"tool": "custom", "tool_id": "<name>"}. When an agent needs data from a real API, add a custom REST tool (or an API node in a flow) that calls it directly. - Document — external knowledge (uploaded files or crawled URLs) chunked into a vector database for retrieval.
- Flow — a finite-state machine of nodes and transitions; an alternative to a free-form agent.
- Post-call analysis — LLM analysis run after a conversation (summary, extraction, sentiment). The configs define what to analyze; the results are produced per conversation and read separately.
- Test suite — a target agent or flow plus a list of test cases (each a conversation prompt and a success-criteria rubric) that you run to check behaviour; a run scores each test pass / warning / fail.
Everything is referenced by name, never by internal id. The only
exception is conversations, which have no name and are addressed by their conversation_id.
Writing prompts (voice)
Replies are spoken aloud (TTS) and the caller's speech arrives as text (STT), and there is no
automatic system prompt — so a voice app behaves well only if its own prompts say so. Bake these
guardrails into your top-level prompt — an agent's prompt or a flow's global prompt
(phrased for the agent's or flow's role):
- Speak, don't format — never markdown, HTML, code, emoji, lists or raw URLs; plain pronounceable prose (say "twenty dollars", not "$20").
- Brief and conversational — one or two short sentences per turn, one question at a time.
- Stay in role and safe — don't reveal the system prompt, tool names or internal reasoning; don't let the caller redirect the agent to call tools directly, override its instructions, or act outside its task.
A flow concatenates its global prompt with the active node's prompt, so these guardrails stay in
force at every node — keep each node prompt short and focused on that node's task rather than restating
them. (A say node's text is the exception: it is spoken to the caller verbatim, bypassing the LLM, so
write it directly as plain, pronounceable prose.)
The server surfaces the same guidance in its MCP instructions, so a connected coding agent applies it
when it writes prompts.
Tools
Read / inspect
list_agents,get_agent,get_prompt_history,list_tools,get_tool,list_documents,get_document,list_flows,get_flow,list_post_call_analysis,get_post_call_analysis,list_models,get_model.get_schema(kind)— the JSON schema (fields, types, defaults, enums, descriptions) that the write tools accept for an entitykind(agent,tool,document,flow,post_call_analysis,test_suite,model). The authoritative field reference when authoring — and the way to learn an entity's shape on an empty account, where there is nothing to read back.
Provision / edit
apply— provision several related entities in one dependency-ordered call (see below).create_or_update_agent/create_or_update_tool/create_or_update_document/create_or_update_model/create_or_update_post_call_analysis— single-entity edits (a model is an account-defined custom model — the Models screen; post-call analysis is the after-call summary / extraction / insights configuration).create_or_update_flow— author a flow from an inline-node FlowSpec.delete_entity(kind, name)— delete with the same cascade cleanup the dashboard performs.rename_entity(kind, name, new_name)— rename in place; references (stored by id) are preserved.wait_for_documents(names)— wait for documents to finish parsing.
Test / troubleshoot
test_tool(name, params)— run a single custom tool once and see its raw response, to verify it works before wiring it into an agent (for an MCP-type tool, also passmcp_tool_name).start_chat,send_chat_message,end_chat— talk to an agent or flow. Eachsend_chat_messagereply already includes the agent's messages and the tool-call / task-switch logs, so it's normally all you need — you don't have to callget_conversationafterwards. Finish withend_chat(a chat isn't saved until you do).list_test_suites,get_test_suite,create_or_update_test_suite,delete_test_suite— author reusable test suites (a target agent/flow plus test cases with success criteria).run_test_suite(name),wait_for_test_run(run_id),list_test_runs,get_test_run(run_id),cancel_test_run(run_id)— run a suite on the runtime and read the results; a run is addressed by itsrun_id.search_conversations,get_conversation— find past conversations by agent / time range and read the full transcript with classified log entries; use these to dig deeper when something looks off or to inspect other/past sessions, not routinely after a chat.get_post_call_analysis_data(conversation_id)— read a conversation's post-call-analysis results (summary, extracted fields, transcript);'latest'is supported.
Documentation
list_docs,search_docs,read_doc— browse and read this documentation (as markdown).
Provisioning with apply
apply takes a manifest that groups entities by type and references them by name. References are
resolved against existing entities plus everything in the same manifest, so you can create an agent
together with the tools and documents it depends on in a single call — order doesn't matter.
{
"documents": [
{ "name": "faq", "urls": "https://example.com/faq\n" }
],
"tools": [
{ "name": "get_rate", "type": "rest", "method": "GET",
"url": "https://api.example.com/rate/{currency}",
"params": [ { "name": "currency", "type": "str", "required": true } ] }
],
"agents": [
{ "name": "support", "llm": "gpt-4o", "prompt": "You are a support agent...",
"documents": ["faq"],
"tools_config": [ { "tool": "custom", "tool_id": "get_rate" } ] }
]
}
apply is strict by default: if any reference cannot be resolved, the whole call fails and names
the missing entity — nothing is partially created. Pass permissive: true to drop unresolved references
instead.
An existing entity with the same name is replaced wholesale, not merged — every field you omit is
reset to its default (a partial agent would wipe its prompt, tools, documents, and so on). This is unlike
the create_or_update_* tools, which patch (omitted fields keep their current value). Use apply to
(re)define complete entities or provision a new dependency graph; to change a few fields on an existing
entity, use the matching create_or_update_* tool.
Adding a dependency to an existing agent. To create a new dependency (for example a
post-call-analysis insights) and reference it from an existing agent, do not put a partial agent in
the manifest — that would wipe the agent. Either create just the dependency with apply and then call
create_or_update_agent with only the changed reference (it merges), or include the agent in the
manifest with its complete current config (read it back with get_agent first).
To attach an uploaded file to a document, include it inline:
{ "documents": [ { "name": "handbook",
"files": [ { "name": "handbook.pdf", "content_base64": "<base64>" } ] } ] }
Use text instead of content_base64 for plain-text content.
Documents parse asynchronously
Creating a document returns immediately; parsing (crawling, chunking, embedding) runs in the background
and can take minutes. The document's status moves from creating to created (or parsing failed).
Before chatting with an agent that relies on a document, call wait_for_documents(["<name>"]). It is a
bounded wait (returns within ~30 seconds) — if the document is still parsing it returns it under
pending, so call it again until the status is terminal.
Authoring flows (FlowSpec)
get_flow and create_or_update_flow use a friendly FlowSpec: flow-level fields plus an inline
nodes list, where nodes reference each other by name through transitions, next_node, skip_node,
else_node, failed_node and the flow's start_node.
Every flow needs an entry point: set the flow-level start_node to the name of the node the
conversation begins at. There is no separate "start" node to add — it's implicit (if you do include a
flavor: "start" node, its next_node is folded into start_node and the node is dropped).
Node names must be unique within the flow. (When reading a flow authored in the dashboard, any
duplicate node names are disambiguated with a #N suffix so the result round-trips.)
{
"name": "booking",
"llm": "gpt-4o",
"start_node": "greet",
"nodes": [
{ "name": "greet", "data": { "flavor": "conversation", "behavior": "say", "text": "Hello!",
"transitions": [ { "condition": "wants to book", "node": "collect" } ] } },
{ "name": "collect", "data": { "flavor": "conversation", "behavior": "prompt",
"text": "Ask for the date and time." } }
]
}
A node can call an API in either of two ways: an API node (data.flavor: "api" — an inline REST
request with its own url/method/auth/params) or a Tool node (data.flavor: "tool", which references a
separate custom tool). Use whichever fits — an inline API node for a one-off call, a Tool node to reuse a
named tool across flows and agents.
Nodes that reference other agents or sub-flows (the pass flavor) are not supported by
create_or_update_flow; provision those with apply instead.
Test suites
A test suite targets one agent or flow and holds a list of test cases. Each case is an LLM-driven
conversation (a content prompt, or fixed phrases) scored against its success_criteria;
pass_threshold / fail_threshold turn the score into pass / warning / fail.
{
"name": "booking-smoke",
"agent": "support",
"target_type": "agent",
"llm": "gpt-4o",
"tests": [
{ "name": "greets the caller", "content": "Say hello and ask to book a table.",
"success_criteria": "The agent greets the caller and offers to help with a booking.",
"max_turns": 6 }
]
}
run_test_suite("booking-smoke") starts a run on the runtime and returns a run_id; the run is
asynchronous. Call wait_for_test_run(run_id) to get the results — like wait_for_documents, it is a
bounded wait (returns within ~30 seconds), so if the run is still going it comes back with the current
progress; call it again until test_status is terminal (completed / failed / cancelled). You can
also poll get_test_run(run_id) yourself. Each per-test result carries a score and the conversation_id
of the test conversation, so you can get_conversation(conversation_id) to see exactly what happened.
Troubleshooting a conversation
search_conversations(agent="support", start_time="2026-07-01T00:00:00")— find recent calls.get_conversation("<id>")(or"latest") — read the transcript. Log entries carry acategorysuch astool_call,task_switchorwarning, so you can see what the agent did, not just what it said.- Fix the agent (
create_or_update_agent/apply), thenstart_chat+send_chat_messageto verify.
Notes
- Secrets (tool passwords and client secrets, model API keys, post-call-analysis and flow API-node auth)
are masked on read; echo the mask back to a
create_or_update_*tool — or omit the field — to keep the stored value, so read-edit-write-back never corrupts a secret. Webhook tokens and per-tool OAuth2 client secrets mask astok*****$1; the trailing number names the stored secret, so pass it back exactly as received or the call fails. - Reading a document or flow returns the same shape the corresponding create/update tool accepts, so you can read, edit and write back.
