mcporter v0.8.0 Release Notes

Source: https://github.com/steipete/mcporter/releases/tag/v0.8.0

[0.8.0] - 2026-03-29

CLI

• Preserve OAuth flow vs post-auth transport failures so invalid OAuth/provider errors surface directly, while real legacy 404/405 transport mismatches still fall back to SSE correctly. (PR #97, thanks @mavam)

• Ignore static Authorization headers once OAuth is active so imported editor configs cannot override fresh OAuth tokens. (PR #123, thanks @ahonn)

• Keep mcporter call --output json parseable by emitting valid JSON even when the command falls back to raw output. (PR #128, thanks @armanddp)

• Render resource content blocks in call output helpers instead of dropping them, including markdown resources and JSON text payloads. (PR #124, thanks @mvanhorn)

• Preserve full JSON/error payloads when data is just one field instead of collapsing the response to data alone. (PR #106, thanks @AielloChan)

• Generated CLIs now parse object-valued flags as JSON and render object placeholders/examples with JSON-shaped help text, so tools like Jira fields no longer receive raw strings. (PR #114, thanks @v2nic)

• Deduplicate concurrent keep-alive daemon restarts per server so repeated fatal errors only force-close the cached daemon transport once before retrying. (PR #125, thanks @zm2231)

• mcporter config add now accepts plural --args as an alias for repeated stdio arguments, matching common CLI muscle memory. (PR #93, thanks @Jah-yee)

• Preserve default imports when mcporter config add writes a config file, instead of forcing "imports": [].

• OAuth: avoid crashing on headless Linux when xdg-open is unavailable; clear stale dynamic-port client registrations; close callback server if stale-client persistence reads fail. (PR #72, thanks @mgonto)

• Added optional oauthScope/oauth_scope config override as an escape hatch for providers that require explicit scopes.

• OAuth wait/redirect now share one deferred to eliminate authorization race windows and preserve stable close-path errors, including wait-before-redirect and repeated-redirect flows. (PR #70, thanks @monotykamary)

• createCallResult().json() now collects all parseable JSON entries from MCP content arrays (single item stays backward-compatible), and raw inspect depth now stays readable without unbounded traversal. (PR #91, thanks @Blankdlh)

• Added --raw-strings (numeric coercion off) and --no-coerce (all coercion off) for mcporter call argument parsing so IDs/codes can stay literal strings. (PR #59, thanks @nobrainer-tech)

• Added CallResult.images() plus opt-in mcporter call --save-images so image content blocks can be persisted without changing existing stdout output contracts. (PR #61, thanks @daniella-11ways)

• OAuth transport retries now classify HTTP 405 as HTTP (not auth) and OAuth promotion applies to configured HTTP servers too, so post-auth fallback flows no longer drop credentials on 405-only endpoints. (PR #48, thanks @caseyg)

• Config loading now parses project and explicit config files as JSONC, so mcporter.json / mcporter.jsonc can include comments and trailing commas. (PR #42, thanks @aryasaatvik)

• Added generated mcporter.schema.json plus pnpm generate:schema for IDE autocomplete/validation, including $schema and oauthScope/oauth_scope coverage. (PR #43, thanks @ahonn)
