- load package.json from the parent folder or parent's parent depending on file existence in parent.
- move the load of package.json into callMethod function, which is the only place it is used, and is closer to where it is referenced.
- New feature: Connection Type
- Reverts "fix: filter out client_secret when storing OAuth client information"
- Fixes STDIO "Headers is undefined" message when connecting to an SSE server.
- set TS SDK to 1.17.5, which has the automatic log level handling
* In useConnection.ts
- push the logging/setLevel message onto the message history stack so it is clear in the Inspector that it has been sent.
- Introduced integration tests for header functionality in a new script `cli-header-tests.js`.
- Updated the `package.json` to include the new test script and modified the existing test command to run all tests.
- Adjusted the main CLI exit behavior to ensure proper termination in CI environments.
- Added `.claude/settings.local.json` to `.gitignore` to prevent local settings from being tracked.
Make both clients use name from package.json for consistency and protocol clarity
- web client changes `mcp-inspector` -> `inspector-client` (package.json)
- cli client remains `inspector-cli` (package.json)
Adds stdio inheritance to prevent Node.js from dropping console output after 8192 characters due to premature stdout pipe closure before output finishes flushing. Without this, calls like this would truncate after 8192 characters, leading to broken json output:
```
npx --node-options=--inspect -y @modelcontextprotocol/inspector --cli --config .mcp.json --server notion --method tools/list
```
```
# notion mcp server
"notion": {
"//": "doppler needs to expose OPENAPI_MCP_HEADERS (and NOTION_TOKEN within it)",
"command": "bash",
"args": [
"-c",
"doppler run -p 'mcp' -c \"user_${MCP_USER:-$USER}\" -- npx -y @notionhq/notion-mcp-server"
]
},
```
You can see this in their [openapi spec](https://github.com/makenotion/notion-mcp-server/blob/main/scripts/notion-openapi.json), which powers their MCP server.
- Add --header option to both wrapper CLI (cli.ts) and main CLI (index.ts)
- Support multiple headers with "HeaderName: Value" format validation
- Pass headers to HTTP and SSE transports via requestInit.headers
- Add parseHeaderPair function for proper header parsing
- Fix output truncation issue by removing forced process.exit(0)
- Update types to include headers in Args and TransportOptions
Usage: --header "Authorization: Bearer token" --header "X-Custom: value"
Test 30 now expects an error when multiple servers exist, even with
"default-server" present, aligning with the simplified logic that only
auto-selects when there's exactly one server.
Only auto-select when there's exactly one server in the config file.
Removes special handling for "default-server" naming convention.
Addresses review feedback from @ochafik on PR #661
- Add --transport option to command line parser
- Support --transport stdio/sse/http flags
- Convert 'http' to 'streamable-http' internally
- Fix transport type conversion for CLI mode
- Pass URL as command for SSE/HTTP configs instead of empty string
- Update runCli to pass transport type flag when needed
- Update tests to expect connection errors for non-existent SSE/HTTP servers
