MCP server 'bocha' not connected because "-" in the name of mcp_servers

[cheanus]

Description

Agent wants to use a MCP tool, but it returns an error: MCP server 'bocha' not connected. This is because the name of the mcp_servers in config.toml is "bocha-search", while the output of extract_mcp_server(tool_name) is "bocha", which is inconsistent and leads to the error. if removing "-" from the name of mcp_searvers in config.toml, it will return to normal.

Expected Behavior

When calling the MCP tool, extract_mcp_server(tool_name) can parse the tool_name normally, so that the agent can call the tool normally.

Steps to Reproduce

Take "bocha-search" as an example. The config.toml is:

[[mcp_servers]]
env = ["BOCHA_API_KEY"]
name = "bocha-search"

[mcp_servers.transport]
args = [
    "--directory",
    "/home/test/Codes/mcp/bocha-search-mcp/",
    "run",
    "bocha-search-mcp",
]
command = "uv"
type = "stdio"

The agent.toml:

# ……
[capabilities]
tools = ["mcp_bocha_search_bocha_web_search"]

Now start openfang and agent. Let the agent use the tool, and it will show the error "MCP server 'bocha' not connected".
