X

Quick start

Always invoke through the local HTTP wrapper. The wrapper starts this skill's local XMCP server on loopback when needed, waits for readiness, and then calls mcporter. OAuth vault seeding happens separately through scripts/setup.sh before agent use.

uv run --script {baseDir}/scripts/local_http_invoke.py list maverick-x --schema

For structured output:

uv run --script {baseDir}/scripts/local_http_invoke.py call --output json maverick-x.<tool> key=value

Safety

Write operations that post, delete posts, reply, repost, like, follow, edit, or otherwise publish externally visible X content require explicit user confirmation with the exact final text or action. Search and read tools are safe to call freely while exploring. Resolve user handles and post IDs before acting on them.

Authentication

Credentials are provisioned at setup time by scripts/setup.sh (a thin delegator to scripts/init-mcporter-oauth.sh) and stored in mcporter's local vault. The setup hook requires these credential env vars:

• MAVERICK_X_MCP_REFRESH_TOKEN
• MAVERICK_X_MCP_CLIENT_ID
• MAVERICK_X_MCP_CLIENT_SECRET
• MAVERICK_X_MCP_ACCESS_TOKEN

For refresh-aware seeding, setup also reads optional expiry metadata env vars when the provisioner supplies them:

• MAVERICK_X_MCP_EXPIRES_AT
• MAVERICK_X_MCP_EXPIRES_IN
• MAVERICK_X_MCP_REFRESH_TOKEN_EXPIRES_AT

mcporter refreshes expired X access tokens through X's OAuth2 token endpoint before calling the local XMCP server. If calls keep returning HTTP 401 after retry, the OAuth grant has likely been revoked or expired; reconnect the integration.

Data flow

Tool calls travel from the agent to mcporter, then to this skill's local XMCP server at http://127.0.0.1:8765/mcp. The local server forwards X API requests with the bearer token supplied on each MCP request. X sees the post, user, timeline, and search data referenced by each call. Use this skill for X-related work only; do not pass unrelated sensitive content through these tools.

Dependencies

• mcporter (github.com/steipete/mcporter) — MCP CLI used to invoke the local MCP server. Auto-installed via npm install -g --ignore-scripts mcporter if missing on PATH (see install spec in frontmatter). The install spec uses unpinned mcporter (npm latest); operators with strict supply-chain controls should override the install to pin a specific version.
• uv (docs.astral.sh/uv) — runs the Python wrapper and local XMCP launcher from inline script metadata.
