Module mcp 

Async MCP (Model Context Protocol) implementation.

Structs

McpAuthConfig

Optional auth block on a remote MCP server (sse / http transports).

McpCallRecord

One completed MCP RPC or tool invocation (sanitized for UI).

McpConfig

Full MCP configuration from mcp.json

McpConnection

McpDiscoveredItem

McpManagerSnapshot

McpPool

Pool of MCP connections for reuse

McpPrompt

Prompt discovered from an MCP server

McpPromptArgument

Argument for an MCP prompt

McpReloadReport

Summary of an in-place MCP pool reload (config diff + optional reconnect).

McpResource

Resource discovered from an MCP server

McpResourceTemplate

Resource template discovered from an MCP server

McpServerConfig

Configuration for a single MCP server

McpServerSnapshot

McpTimeouts

Global timeout configuration

McpTool

Tool discovered from an MCP server

Enums

ConnectionState

State of an MCP connection

McpTransportKind

Which wire transport a server uses. Resolved from the explicit transport/type config field, falling back to inference from command (stdio) vs url (SSE, for backward compatibility).

McpWriteStatus

Functions

add_server_config

discover_manager_snapshot

extract_tool_content

Extract the model-facing content from an MCP tools/call result.

format_tool_result

Human-readable rendering of a tool result, prefixing Error: on failure. Prefer is_tool_error + extract_tool_content on execution paths that need to map failures onto a structured error type.

get_server_entry

Load a single server block from mcp.json (for edit UIs).

init_config

is_tool_error

Whether an MCP tools/call result signals a tool-level failure via the spec’s isError flag. This is distinct from a JSON-RPC protocol error (handled in connection.rs): a tool can return a successful RPC response whose payload still represents a failed tool invocation.

load_config

manager_snapshot_from_config

manager_snapshot_from_pool

Build a manager snapshot from a live pool (shared sidecar pool / hot-reload path).

merge_mcp_json_fragment

Merge servers (and optionally timeouts) from a JSON fragment into mcp.json.

merge_preserved_secrets

When the UI saves a server block after a redacted GET, restore secret fields that were omitted (not re-entered by the user).

recent_mcp_calls

Recent MCP calls, newest last (up to [MAX_RECENT_CALLS]).

record_mcp_call

Record a completed MCP operation for the desktop diagnostics panel.

remove_server_config

remove_server_from_config

Remove a server entry and persist. Returns true when removed, false when the name was already absent (idempotent).

replace_server_in_config

Replace an existing server block (full document for that key). Errors if the name is missing.

save_config

set_server_enabled
